Last Updated July 27, 2020


  • Combines DMHA and DMAA
  • Enhances motivation and mood
  • Strong energy and focus
  • Strongest for focus and euphoria
  • Hits exactly like the original Craze (Driven Sports)
  • Hard hitting and lasts for long periods

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.

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.

Advanced bodybuilders may even avoid these and opt for non-stimulant pre workouts 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.

Check out a pre workout like Assassin or Crack for something that is strong.

Check out Kreed, a pre workout that combines both DMHA and DMAA in one strong formula

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

Update: Aggressive Labz has released a pre workout with DMHA/ DMAA for a limited time.

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

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)

Jack3d is one of the first pre workouts on the market with DMAA.

When it was discontinued, other pre workouts like Mesomorph took over.

But now it's hard to find any pre workouts at all with DMAA.

Surprisingly, Jack3d is back and it has nearly the exact same formula as the original.

This time however, DMAA is not only back in Jack3d, but it also comes with a hard hitting combination of stimulants like DMHA and 405mg of caffeine!

Per scoop, you'll only get around 100mg caffeine, and 25mg DMAA.

To get the full 405mg caffeine and 75mg DMAA, you'd need to use 3 scoops.

Surprisingly, it still contains the weakest nitric oxide boosters known to supplement users and that's arginine.

The problem with arginine is that it's not very bioavailable and there are much better options like agmatine and citrulline.

However Jack3d is still fairly cheap and it's mainly back for it's stimulants.

For energy, you won't find anything stronger.

The rest of the ingredients are in a prop blend so you won't really know how much beta alanine and creatine you're getting.


  • Combines powerful stimulants
  • Discloses DMAA and caffeine
  • Increases focus and energy
  • Nearly the same as the original


  • Prop blend

Crack is one of the strongest pre workouts we’ve seen yet.

You couldn’t ask for something better…

With 6 powerful nitric oxide boosters, this is actually better than most pre workouts for pump. 

DMAA has a bit of a risk for elevating blood pressure when the dose is over 80mg. 

However that becomes less of an issue as nitric oxide boosters expand blood vessels, allowing for more blood flow and oxygen to be delivered to working muscles.

This packs over 12g of nitric oxide ingredients so you'll not only feel like you're at the top of the world with the energy, but you'll be motivated to lift harder and longer as the pump will get better throughout your workouts. 

It includes arginine nitrates, agmatine sulfate, citrulline and more. These nitric oxide compounds work to increase N.O. levels, keep them high and prevent them from dropping so you get long lasting pumps. 

The nitric oxide profile is one of the best we've seen in DMAA pre workout. Especially with one that has such a high amount of stimulants. 

You can take half a scoop and you'll still get enough of every ingredient.

  • Completely transparent label
  • Uses maximum doses of nitric oxide boosters


  • Big dose of DMAA (120mg)

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

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

Update: Dark Energy is listed as “Mystery Pre Workout” to prevent unwanted attention that may leave it discontinued.

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!

Read up our review on Dark Energy here.

Top 10 Strongest Pre Workouts With Exotic Stims

Arez Super is the next best pre workout that comes with a strong energy blend.

It not only enhances energy with caffeine but it also has nootropics, nitric oxide boosters and a nice mix of stimulants.

While it doesn't have any DMHA or exotic stimulants, it uses Eria Jarensis, which is a strong euphoria enhancer, along with other mood enhancers that work in synergy.

Aside from the stimulants and ergogenics, there's fat burning compounds here that'll make you sweat buckets.

The tiny dose of GBBgo is actually as strong as it gets as it's a highly bioavailable form of carnitine.

All in all, Arez Super is jam packed and it does everything and more than a pre workout that has DMHA.

Check out the review here.


  • Intense energy and focus
  • Increases power and strength


  • None

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

Update: Take a look at the latest pre workout by NTel, Arez Super.

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 big-time with the GOD-like 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!

For 5% off, use this coupon code: FITFREK5


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


  • Several under-dosed ingredients
  • Not enough pump ingredients - the two this product does have are not dosed high enough
  • 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
