Last Updated September 20, 2019


  • Best Craze replacement
  • Enhances euphoria and motivation
  • Strong energy and focus


  • DMAA powered pre workout
  • Full disclosed dosages
  • 4 sources of stimulants for long lasting energy

From the hardest hitting to the aggressive, this strongest pre workout guide has it all.

If you're looking for complete pre workouts for bulking with ergogenic ingredients, then check out our regular pre workout guide here.

Whether you’re looking for legal amphetamine or the next “craze”, there’s sort of a trend that goes towards the “stim filled” pre workouts.

And I get trust me.

You might want to get up at 5 am, and hit the iron super hard or you might come back sick and tired from work…

So you'd want a pre workout that hits you harder than anything else in the world but at the same time, you don’t want to take crack.

If you're not already taking your basic supplements like ZMA and creatine, then you might not be making the most out of these pre workouts.

The 3 main stimulants we split pre workouts by are standard, exotic and DMAA.

Exotic stimulants can include DMHA and Eria Jarensis.

While our DMAA list can include DMAA, but some pre workouts are coming out with both DMAA and DMHA in one, so they are included in this list.

Here are the main stimulants to look for…

The Stimulants To Look For



One of the most studied chemicals substances. Increases alertness, energy and has potential as a nootropic. Doses of 300mg is proven most effective at burning fat and increasing performance.


Chemical structure closely resembles an amphetamine. DMAA enhances focus, uplifts mood and burns fat while increasing performance. Works best when combined with caffeine. Doses of up to 90mg is proven to be completely safe.


Has 80% of DMAA effects and works similarly in boosting dopamine and noradrenaline levels. <br>Doses of 100mg to 150mg is comparable to 35-50mg DMAA. If it's 2-amino-5-methylheptane then 75mg is good.

Skip down to our final top 10 list or scroll down to choose according to your preferences.

You can stack these pre workouts with ANY nitric oxide supplement, that does NOT have caffeine or any other stimulants. (See our nitric oxide buying guide).

If you're on a budget and want to save money, keep up with our Best Deals / coupon discounts page.

Stim bombs, aggression inducing, motivation enhancing, we've got it all (or try to).

These pre workouts are absolutely not for beginners or weak hearted.

There's 3 main lists you can look at:

  • Standard stimulants (no DMAA or DMHA. Just caffeine)
  • DMAA.
  • Exotic stimulants (DMHA and Eria Jarensis)

Some pre workouts have both (DMHA and DMAA). In that case, look at our DMAA list.

Which list do you want to see?

Advanced bodybuilders may even avoid these and opt for non-stimulant pre workouts as they are generally beneficial for performance and gains.

The final and last top 10 list will show you our hand picked pre workouts (strongest of them all), while the other sections will show you anything from the most aggressive to the most focus-enhancing pwo's.


Unless you want to lay in bed for many days in a row feeling drained as a peach that is out of its season, don’t abuse these pre workouts.

The withdrawals are the worst.

(Click here to skip down to the cycling stimulants guide below)

You don't want to be a slave to caffeine and other stimulants.

In other words don’t use them more than 3 times (4 max) a week.

Get another pre workout with less stimulants because once you go off these hard hitters, you’ll feel soo drained and tired that you’ll feel completely useless.

Do check out our DMAA or Ephedra top 10 list for those specific stimulants.

Warning: Limit your caffeine sources.

While you’re using a stimulant filled pre workout, or any pre workout for that matter, don’t drink coffee or consume anything with caffeine (including pepsi and other soda drinks)

You’re going to workout for the muscle gains, not for the “chasing the dragon high”.

Use these with a proper bodybuilding routine, good nutrition and possibly a mass gainer or a protein powder, and you've got yourself on the road to more gains…

Do your research.

There are many compounds out there that can enhance size and strength, even natural solutions like Laxogenin which is seen as the “plant steroid”.

Best Pre Workouts For Women...?

If you're wondering where our “best pre workouts for women” are, well you're at the right place.

Let me break the news to you… there's no such thing as a pre workout for women.

Would Starbucks label a cup of coffee for women / men?

Sure they could brand and cater it towards a gender but the ingredients wouldn't be all that different.

If you can handle 300mg caffeine along with DMAA (check out our DMAA top 10 list here) and other stimulants, then you're fine with any of these pre workouts.

However if you're a beginner, or even advanced, you should always take a quarter of a scoop of any pre workout to assess your tolerance and work your way from there.

You may even benefit from just taking half servings throughout the entire bottle.

So ladies, don't spend the extra buck to get the specially marketed products that are geared towards you.

Just get anything that you can handle, and test it out with half a serving or even less.

Craze Replacement

We've found a pre workout that just may replace Craze, at least in the focus department.

You've been searching for that very pre, and we have too but none of them ever came close, not even their latest “Frenzy” (forget about Craze V2 it won't replace the first version).

Craze was the only pre workout that could produce that awesome tunnel focus along with strong euphoria, although there was more than likely to be banned substances in it.

So you'd like to have some of that tunnel focus again, which is possible, though the euphoria aka “feel good energy” may not be there.

Check out the list below for the best alternative for Craze.

Aggressive Pre Workouts

Here you've got pre workouts that'll boost your aggression and get you amped up in a very angry-like fashion.

Obviously that doesn't mean these pre workouts will make you beat up your loved ones (get out of here if it does), but it will make you lock onto your angry emotions and channel it towards every set, rep and exercise.

Motivation, aggression and hunger for more….

That's what we look for when it comes to aggression inducing pre workouts.

Most of these pre workouts have a mix of stims and nootropics that'll make your hands shake and fiend for the cold iron.

There used to be a lot more pre workouts on the market that specialized in this category.

A notable one was Anadraulic State GT by LG Science (ASGT) but it is discontinued for whatever reason.

We have a lot of trouble finding comparable pre workouts if there are any at all.

It's most likely better just to go for a pure testosterone booster like these, some of them will increase aggression.

But here's a few, after endless days and months of researching and looking for something that increases motivation and some good old inner rage like no other. 

Check out these powerful pre workouts….

Top Strongest Pre Workouts With DMAA

Hellnox is another DMAA pre workout to come from Aggressive Labz.

With no signs of slowing down, this formula is as hardcore as you can imagine.

Nootropics, stimulants, strength boosters and nitric oxide are all packed in this underground-looking pre workout.

Hellnox discloses a lot of ingredients but the downside is that they have a few in a prop blend.

You don't know how much of the nootropics you're getting, but at the very least, DMAA and caffeine are both disclosed.

And they are at the perfect dosage of 75mg DMAA and 350mg caffeine.

Try Hellnox before it's another DMAA pre workout that's hard to find.


  • Disclosed stimulants
  • ​Effectively dosed
  • ​Strong pumps


  • Prop blends

Leatherfaze is a strange name for a pre workout, but seems suitable for something that is underground.

An advertisement for this pre workout might say something like “DMAA is hard to find and if you need some, then Leatherfaze is the one for you.” and it would sound like the perfect name for such a controversial stimulant.

It has 45mg DMAA, which is the perfect amount as anything over 70mg puts you at risk for higher blood pressure and unwanted side effects.

It packs a lot of ingredients, each scoop packs 20 grams!

Try this out before it's another discontinued DMAA pre workout.


  • Increases energy and focus
  • ​Unique branding
  • ​Fully disclosed


  • Unheard of company

​If you've never heard of Anti-Hero Labs, you're not the only one.

This relatively new company has brought a new DMAA pre workout to the block and it isn't shy to overly do it.

With 100mg of DMAA, you'll never find anything that has close to this dose.

In fact, we recommend never going over 70mg DMAA as it can cause high blood pressure.

Taking a little less than a full scoop will probably be a wise choice with Venom.

It goes without saying…

Use this pre workout with caution!


  • ​Big DMAA dose
  • ​Lots of stimulants
  • High energy and focus


  • ​Prop blend

​You probably know the struggle.

Finding reasonably priced DMAA pre workouts is a mission.

But we're on top of it and here we have another fantastic pre workout that almost looks like it's coming from a pharmaceutical company (and no it's not).

Phenta Inferno is the second DMAA based supplement to come from Atlas Labs.

The fat burner they have is Phenta 1,3.

The DMAA dosage is disclosed, which is great, but the performance boosters are in prop blends (agmatine, hordenine, beta-alanine, and taurine).

Companies will be happy to hide stimulants in prop blends but this one is only disclosing stimulants.

Strange but we'll take it if it has DMAA!


  • Half disclosed label
  • Big stimulant dosages
  • Great for fat burning


  • ​Prop blend

​We ​If there's one thing you'll agree with, we can never get enough of DMAA pre workouts.

There seems to be an endless supply of it, even though it is not as widely available as it once was, it's still easy to find.

Chaotic is a pre workout that contains 80mg DMAA, yes just a little over the safe limit of 70mg.

Anything over 70mg is a bit risky for side effects like increased blood pressure.

Aside from that, there's 350mg caffeine and 3mg yohimbine HCL.

The rest of it is purely for performance and pumps, from beta alanine to citrulline malate and taurine.

The creatine is a bit underdosed but you should be supplementing that anyway.


  • High doses of stimulants
  • ​Great for pumps and energy
  • ​Increases performance


  • 80mg DMAA may increase blood pressure

Surprisingly, Phenta 1,3 has only recently caught our eyes.

This wasn't even available when DMAA supplements were being widely sold.

Phenta 1,3 is one of the strongest we've seen, maxing out each serving at 80mg DMAA, 350mg caffeine, 100mg synephrine and 45mg hordenine HCL.

Hordenine will make the rest of the formula hit harder and longer, so the infamous crash that's assosciated with DMAA will be a little smoother, thanks to it.

Get this before it disappears as it's fairly priced.

  • Maxes out on stimulants
  • Fairly priced
  • Hard hitting and lasts longer


  • Beginners will not be able to lower the dosage (unless the pill is broken)

​We thought pre workouts couldn't get any more intense but Kracked has proven us wrong.

This nasty pre workout has all the hardcore stimulants you've seen in pre workouts and more.

We consider this to be ultra-strong in its finest form.

It combines DMAA, with DMHA , ephedra, eria jarensis and you'd wish it would stop there by the time it kicks in.

Kracked is the stim-junkies dream come true but it can also be a nightmare if too much is taken.

Personally, I would advise using a quarter of a scoop.

This is one of the first to combine DMHA with DMAA and both ingredients are highly dosed.

In fact, to avoid elevated blood pressure and heart rate, DMAA should be dosed way less than 100mg!

Take this at your own risk. Do not take a full serving no matter how experienced you are with stimulants.


  • ​Contains performance enhancers
  • ​Full doses of nitric oxide boosters
  • ​Fully disclosed label


  • ​Super strong
  • Not for beginners

Supplement companies seem to have no limit when it comes to formulating and putting together ingredients.

It's a bad and a good thing.

There are safe limits for stimulants and we're responsible for taking in the safe limits or we'd basically be begging the FDA to ban the good stuff like DMAA and DMHA.

This is one of the few that have both, and thankfully the label is fully disclosed.

The downside is that it was a mission to find the ingredient label since the company's site, Magnitude Life Sciences doesn't even display them.

“Not for human consumption” is what they put on their product page for Dark Energy.

And funny enough they didn't put that for their other pre workouts.

No one can actually promise you the ingredients we've listed here are actually in the pre workout.

What we would recommend is taking a quarter of a serving and working your way up according to your tolerance and “feeling”.

The company's site is only 2 years old and the only reviews we can find is from comments on their Facebook posts.

The good news is that people are raving about this Dark Energy for energy.

But careful with this one!

  • Powerful formula for energy and focus
  • Fully disclosed formula
  • Energy comes on slow and elevates


  • Magnitude Life Sciences doesn't display ingredients

If you're looking for a Mesomorph replacement at a fair price, then look no further.

Juggernaut maxes out DMAA at 70mg, packs beta alanine and enough performance boosters to help power you through your workouts.

At one scoop, all doses (except creatine) at maxed out.

There's only a one or two pre workouts that seem to outdo Irate in their ingredients but Irate has been out a little longer and the price is lower. 

For something that has DMAA, this pre workout has long lasting energy that will keep going and reduce that infamous crash that strong stimulants like DMAA has. 

Get ready for tingles, energy, and lots of focus, because Irate Extreme delivers everything on point.

DMAA is no longer being produced, so considering how cheap this is, this is a great deal.

Use this for 5% off: FITFREK5


  • Fully disclosed label
  • Maxes out on stimulants
  • Multiple sources of caffeine
  • Mesomorph replacement
  • Great price


  • Not for beginners at full scoop

​Top 10 Strongest Pre Workouts With Exotic Stims

Improved and reformulated, DVST8 is back.

But with the removal of DMHA, you'd wonder if this still a hard hitter.

DVST8 packs quite a punch still as it contains 350mg caffeine, 100mg theobromine, 30mg synephrine and 4mg alpha yohimbe.

And to top that off, it uses the amazing mood enhancing compound, 200mg Eria Jarensis and a massive 120mg of the new stimulant, Dynamine.

That's the most Dynamine we've ever seen in a pre workout!

Everything else is either at the bottom of prop blends, or just very minimally dosed.

DVST8 is here to help you destroy your workouts.

The pumps are insane with the combination of 6g citrulline and 2.5g GylcerPump, along with the performance and strength boosting beta alanine (3.2g).

With everything on the label is fully disclosed, so you're no longer guessing what the stimulant dosages are.

Try out DVST8 and use our coupon code: FITFREK5


  • Fully transparent label
  • ​Can be taken at half the serving
  • ​Mix of stimulants for energy and long lasting focus
  • ​Will increase pumps and performance
  • ​Huge dose of Dynamine (120mg)


  • ​Expensive
  • Alpha Yohimbe dosage might be too high for some people (4mg)

An ideal pre workout shouldn't only contain strong stimulants but it should also have strong performance booster.

And that's what BZRK has done for us.

This formula is packed with stimulants and performance boosters.

But the downside to this formula is that it doesn't tell you how much caffeine you're getting or any stimulant for that matter.

The addition of GlycerPump, betaine anhydrous and citrulline malate will get you looking full and pumped for days at a time!

Get BZRK and try it out.


  • ​Increases nitric oxide and performance
  • Nice mix of stimulants
  • Fully dosed strength and intensity boosters


  • ​Big prop blend of stimulants

​If you’re looking for one of the strongest pre-workouts with exotic stims, look no further than Arez Titanium God of the Gym by NTel Pharma.

Arez is a pre-workout that has been around in various forms and has always been loaded with stims and focus enhancers – we’ve seen Arez White, Arez Black, Arez God of the Gym and now the new Arez Titanium God of the Gym.

This version charges out of the gate with full disclosure labeling.

However, with an underdosed pump complex that consists of a 3 gram dose of pure citrulline, and 500 mg of agmatine, it stumbles just a bit, even with a clinically dosed 3.2 grams of  beta-alanine.

Wait a minute though – it comes through bigtime with the GODlike Energy Surge complex – and it is exactly what the name says!

First up is PEA (or B-PEA), eria jarensis a little under-dosed and a second form of PEA, so you’re getting two forms of this potent mood/cognitive enhancer.

Next, there’s a huge 175 mg dose of juglans regia – the natural form of DMHA, which is a little stronger than the artificial version because it absorbs much better, it also gives a cleaner energy.

These ingredients alone are a great start to this exotic complex but we still have a potent 350 mg dose of everyone’s favorite stimulant, caffeine, followed by synephrine, yohimbine bark, a solid 250 mg dose of the powerful cognitive enhancer choline, and finally a low dosed 10 mg of the stimulant hordenine.

Overall, that’s quite a stim complex – so, while there is a somewhat weak pump complex, this is a pre that’s more about energy, focus and mood elevation and its not afraid of using exotic ingredients.

The value is OK with 25 servings and 1 scoop per serving, but with a higher than average price.

However – if you want to feel like a God of the Gym and don’t exotic stims, Arez Titanium God of the Gym is one of the strongest pre-workouts on the market!

  • ​Full disclosure labeling
  • ​Intense energy
  • Excellent focus & alertness
  • ​Excellent mood elevation
  • Good stim/focus complex


  • ​Several under-dosed ingredients

  • ​Not a great value - priced high with 25 1-scoop servings

You'd think by now companies would be able to not use Labz in their names.

But we needed to rank this one as it is a definitely a Stim Reaper.

And maybe a heart reaper?

Killer Labz is a semi-hardcore company when it comes to pre workout formulas.

Stim Reaper is packed with the good stuff, Eria Jarensis to DMHA and a whole bunch more.

This completely disclosed label uses 250mg of Eria Jarensis, 100mg DMHA, 750mg choline bitrate and 10mg huperzine for super long lasting focus.

The huperzine will ensure all-day focus with little to no crash from DMHA.

The 400mg of caffeine is more than enough for stim junkies, but maybe a bit overboard for those who are used to pre workouts like Pre Jym and Kaged.

Overall Stim Reaper is a simple but strong formula.


  • Formula is completely disclosed
  • Uplifts mood and has a bit of euphoria
  • Big doses of stimulants
  • All day focus with nootropics


  • None

Defiant Unleashed is one of the best formula's we've seen so far.

It pairs high doses of DMHA, eria jarensis and caffeine with 2 long lasting focus enhancing nootropics, huperzine and choline.

Smooth focus is already going to be there thanks to the combination of DMHA and caffeine, but huperzine makes it last all day without causing any sort of crash.

It even has the basics, citrulline and beta alanine, although that's not needed in a pre workout, it's nice to have.

Check out Defiant Unleashed and use 5% off coupon code FITFREK5 for further savings.


  • High doses of stimulants
  • ​Increases mood and energy
  • ​Smooth, long lasting focus
  • ​Perfect mix of nootropics
  • ​Fully disclosed
  • 30 full servings


  • ​Almost none other than its expensive but worth it

Alpha Lion is a super fast growing company that has seemingly come out of nowhere with high quality supplements and cool branding.

Super Human Supreme is a prime example of what they are capable of creating.

This pre workout isn't only powered by 200mg DMHA and 200mg Eria Jarensis, but it also has the new nitric oxide ingredient, S7, which is a blend of green coffee bean extract, green tea extract, and a few others.

S7 has promising effects, even more than 2018's breakthrough ingredient, Nitrosigine.

Luckily this has both in the same formula.

You're going to get long lasting energy with super strong pumps that'll last you for days…

This isn't Super Human, it's Super Human Supreme!

4.HyperMax Extreme by Performax Labs

Performax Labs HyperMax Extreme is updated with big changes to the already popular pre-workout.

The ingredients are packed for pumps and energy.

Originally known as “HyperMax XT”, this pre workout has been heavily upgraded, starting with full disclosure labeling and effective dosing.

HyperMax Extreme is a combination of pump enhancers, energizers, cognitive enhancers and ergogenic aids, providing a complete pre-workout experience.

No doubt about it, this is a high stim/high pump pre-workout – hard to do because stims can restrict blood flow, combatting the pump effect you’re hoping to get.

This product hits it hard with a potent 400mg of caffeine, and that’s supported with 1 gram of tyrosine, which works extremely well when it’s paired with caffeine.

Then there’s 50mg of synephrine, milder but structurally similar to ephedra, and 2mg yohimbine.

For focus and cognitive enhancement, there’s PEA and Eria Jarensis, which is also a form of PEA.

But why two forms of the same ingredient?

According to Performax Labs, the two forms are very synergistic and provide an immediate increase in focus and mood while providing an extended effect.

HyperMax Extreme hits hard with pumps – with 300mg of VASO6, 6g citrulline and agmatine, plus beta-alanine for muscular endurance.

The dosages are for 2 scoops, making it 25 servings in total, but you can still take 1 scoop and get massive pumps and energy.

Even at 25 full servings, it's bucking the trend used by many pre-workouts, which usually advertising 30 1-scoop servings, only to find you need 2 scoops for maximum strength, cutting your 30 servings to 15.

For 5% off, use this coupon code: FITFREK5


  • Full disclosure labeling
  • Well-rounded formula with effective dosing
  • ​Clinical doses of performance enhancing ingredients
  • Good value with 25 1-scoop servings – 1 scoop is all you need


  • ​Uses artificial colors and flavoring

Hydrazine is one of the only pre workouts that is considered to be as strong as the OG Craze.

We’re not referring to crazy, heart-attack filled energy.

Remember the waves of euphoria, energy and focus that users once raved about with the original first ever Craze? 

Expect the same exact feeling with Hydrazine. 

Hydrazine doesn't only have a caffeine-focused formula but it is well rounded with different ingredients to enhance focus and mental clarity.

While it doesn’t have nitric oxide boosters and strength enhancers like Pre-Kaged or Altius) but it works well for energy and focus. 

Check out our in-depth analysis here

This formula, like Craze and Frenzy, does not depend on caffeine.

If you live in the States, the best alternative is Excelsior by Imperial Labs. 

Hydrazine is the best option if you live in the UK or don't mind spending 2-3$ per serving.

It is a tad more expensive than Excelsior.

But if you’re already paying 2$ for drinks from a store or the bar, this might look like a bargain since no other drink at such a low price can give strong waves of focus and euphoria. 

If you’ve taken Detonate by Gaspari, the stuff that people swore had the same “secret ingredients” as the original Craze, then you’ll probably know what to expect with Hydrazine.


  • Best Craze replacement
  • ​1-2 pills per serving for long lasting effects
  • ​Increase in aggression and energy
  • ​Tunnel vision and mood support
  • ​All day energy


  • Expensive
  • Only available in the UK (but ships worldwide)

​Olympus Labs has brought us all kinds of hardcore supplements ranging from test boosters to pre workouts.

Before ​I Am Suprem3, we had a strength and energy booster called Conqu3r Unleashed and it was a popular pre workout for a few years.

It was one we kept coming back to.

Now they've created something beyond anything they've created before, with all new and mostly patented ingredients, it's time to make it “​I Am Suprem3”!

Giant Doses of Nitric Oxide Boosters

​We rarely see this much citrulline being used in any pre workout. ​I Am Suprem3 has a giant 5 gram dose of the pure stuff (equal to about 10g of citrulline malate)… Pumps ahoy!

Besides citrulline, we also have Vaso6, a never used before patented ingredient that promises to enhance pumps beyond anything you've tried before.

And after all this, we still have a nice 1 gram dose of agmatine (AGmass) which will further prolong pumps and enhance mood to keep you uplifted and motivated throughout your workout.

5 Stimulants For Maximum Focus and Energy

​While most of ​I Am Suprem3 is hidden behind prop blends, we still see that this has a nice formula consisting of 5 hard hitting stimulants that'll give you energy from all levels.

Starting with 300mg caffeine for good old fashioned increased alertness and energy, you're also going to feel great thanks to the strong PEA-based ingredient, Eria Jarensis and the DMHA ingredient, Juglans Regia extract.

The blend of stimulants are in a 678mg blend but it is safe to assume that the next two ingredients (Eria Jarensis and DMHA) is dosed fairly high as the last ingredient is St1M-X (extracted from the same plant as yohimbine but could be one of many constituents.)

For 5% off, use this coupon code: FITFREK5


  • ​5 stimulants for maximum energy and focus
  • ​Uses some new and never used before patented ingredients (like ST1M-X and Vaso6)
  • ​Enhances and prolongs the pump for long periods of time
  • ​True one scooper and is affordable
  • ​Concentrated pre workout but still contains large doses for pumps and energy


  • Unsure what ST1M-X is made out of
  • First batch of Dragon's Mist (flavor) was recalled due to ST1M-X being incorrectly dosed


Looking for euphoria? Strong but steady energy? Build up of focus and racing thoughts?

Craze Driven Sports fans, look no further. 

This has the same exact focus and energy that the original Craze had.

No we're not referring to the reformulated versions like Craze V2, or CRZ OG.

W're talking about the original Craze.

Excelsior has similar euphoric feel as the original Craze once had.

Same build up of energy, same happy “feels” and you won't want to leave the gym.

The energy lasts for hours. 

People report they can't sleep if they take it after 3pm (again similar to what Craze users reported).

I personally can’t sleep until 3 am if I take it after 12 pm. 

While it has DMHA and a few other ingredients, it is nothing like any other product that has similar ingredients.

There’s a catch though. 

It's not cheap.

Considering how Craze was sold for as much as $100 (or even more!), this is a great deal in comparison. 

Expect to pay around 60 to 70 USD (or 55-60 euros with shipping). 

That’s around $2 per serving. It’s worth it for some feel good energy and motivation. 

It’s available worldwide, throughout the UK and some stores have it in the US. 

Try Excelsior and look no further, before you find this Craze replacement gone.


  • Long lasting energy
  • ​​Compares to Craze v1
  • Intense focus
  • ​Produces an overwhelming feeling of energy and motivation
  • ​​Various stimulants without being overly dependent on caffeine
  • ​Unique blend of stims


  • Prop blends
  • Affects sleep quality if taken 10+ hours before sleep

Top Strongest Pre Workouts With Standard Stimulants

​This pre workout comes from a controversial company, Driven Sports. 

But Frenzy is not something we can sleep on.


Although Frenzy is not comparable to Craze at all, this pre workout has carved itself a category of its own and nothing has come close to it’s aggressive power.

Think “limitless” aggression and motivation.

We've had multiple tubs of Frenzy and it seems to provide that same aggressive / motivational-like fuel without much of a tolerance issue until the whole tub is consumed then it would be wise to take a break from Frenzy to avoid tolerance.

You'll feel like you're 18 again and have the same motivational, beast-like hunger you had when you first started training.

Caffeine is at the bottom of the formula which is a good sign since it means it's not relying on it for energy.

We'll be the first to admit, advanced bodybuilders will laugh at the formula but mistake it not, as it's a very strong, stim-concentrated pre that is not made for the weak.​

With 140 reviews and a 96% rating, there’s no way that everyone can be wrong about this pre workout.

Combine Frenzy with Craze v2 for limitless focus and endurance (but nothing compares to the original Craze, believe us).


  • Increase in aggression
  • Massive boost in confidence and drive
  • Increases effectiveness each use
  • Tastes like pop (only pre workout that does so far)
  • Can take it late in the evenings


  • Mysterious prop blends
  • Laughable formula (but it works)

​You’ve probably heard of Arez White and Black, both are considered to be epic pre workouts for focus and energy.

Though those 2 pre workouts had DMHA (AREZ White and Black, which will both be discontinued soon!), MEGA-AREZ is absolutely free of exotic stimulants but still has a balance of stimulants to keep you at the top of your game.

MEGA-AREZ was formulated to increase pumps and enhance energy through multiple stimulants and nootropics.

It is powered by 300mg caffeine, along with a nice dose of lotus leaf extract (300mg), paired along with fatigue fighters like rhodiola rosea and velvet bean extract, you’ll be feeling like the god of the gym without any crashing.

It’s disappointing to see only a gram of betaine anhydrous, but it makes up for it by including 3.2g beta alanine which will increase performance by reducing the build up of lactic acid so you can grind out more reps and intensity while increasing time to fatigue.

With a bit more than 4 grams citrulline, you’ll be pumped and have long lasting endurance to rip through your sets.
