Top 10 Strongest Pre Workout Supplements For 2020
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…
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)
- 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.
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.
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.
Or 1,3 Volt, a hardcore DMAA pre workout:
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
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.
Kreed is another hard hitting pre workout with the strongest stimulants.
High octane energy is what you should expect with Kreed as it contains 3 exotic stimulants.
While we don't know the dosages of each ingredient, it DMAA, DMHA and Eria Jarensis.
Any pre workout with DMHA and DMAA will already be a strong pre workout but when you add all 3 to the mix, along with other stimulants, you have a pre workout in it's ultimate form.
Kreed would be even better if it's formula was fully disclosed.
Unfortunately it's not but it is still a worthy pre workout that must be tried at least once.
It also has nootropics to help further maintain workout intensity through focus and cognitive enhancements.

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.
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.
Now for both 1,3 and Inferno, the DMAA dosage is disclosed, which is great, but the performance boosters for Inferno 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!

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.
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.
Aventador is one of the few pre workouts that uses both DMHA and DMAA.
It doesn't just use these two hardcore stimulants.
It uses a few other stimulants including caffeine, synephrine, and N-Methyltyramine HCL.
All of these stimulants are going to fire up your CNS, get your heart rate up and pumped for your workouts.
The interesting part of this formula is the testosterone blend. It includes D-aspartic acid and tribulus.
While tribulus won't have any direct effect on testosterone levels, n-methyl-d-aspartic acid will and this form is suppose to be 100 times better than regular D-Aspartic-Acid.
Aventador also includes a bunch of nitric oxide boosters like agmatine, citrulline and a big dose of taurine for maximum vasodilation.
This pre workout has proven to be a hardcore choice, and the price is more than fair, making it one of the best choices that has both DMHA and DMAA.

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.

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.
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.

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!

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.
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.

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.
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!

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.
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!

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, combating 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.

Assassin is a unique pre workout you wouldn't expect to see because of the ingredients it uses.
Lions mane is rarely used in pre workouts but here it is and it's at a full 1 gram dose.
This ingredient has science proving multiple benefits and it features anti-aging, anticancer, antibiotic properties that make it useful to have in a supplement, and it also has inflammation reducing benefits.
For pumps, it has 4g citrulline, and a full 1g of agmatine. Both of these ingredients work well together to increase nitric oxide levels, and agmatine can protect those levels from dropping.
The stimulants in here are monstrous, from 500mg caffeine, to 500mg phenthylamine, and 300mg eria jarenesis to help enhance mood and motivation.
Assassin v6 has proven to be even better than the previous version with it's complete formula.

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
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.
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.
Update: The latest pre workout by NTel, Arez Super is worth a look for its strong energy and thermogenic effects.
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.
MEGA-AREZ will have you feeling god-mode in the gym. Give this unique pre workout a go!

PreSeries Bulk has it all, from ingredients that enhance nitric oxide levels to ergogenic aids that'll all help performance on all levels.
It packs a complex of stimulants and while it may seem like the caffeine content is very low, it is actually because it has 50mg synephrine, 25mg hordenine and mood enhancing mucuna pruriens.
Focus is not going to be an issue with the help of 500mg choline bitartrate and 600mg N-Acetyl-L-Tyrosine.
