This is the ultimate list of pre workouts in 2021.
And let me be clear about something:
This is NOT your average “Pre workouts in 2021” list.
If you want to see the strongest pre workouts in one place, then you'll LOVE this list.
I personally tested over hundreds of pre workouts and have researched for months on the lookout for the best.
If you want daily drivers, then check out our other ranking list.
If you want something without insane energy and made for beginners, then check this.
Update 03/30/21: We have heard from a trusted source that Static Labz and Dark Energy's companies have been raided by the FDA. We may soon see DMAA disappearing from the market again.
Most of the coupon codes for any recommendations we make should either be FitFrek (or FitFrek10).
You can stack any of these pre workouts with a non-stim nitric oxide booster.
For more discounts and special deals, check out this page.
So if you're looking for the strongest pre workouts, you're in the right place…
So you want to turn any pre workout into a DMAA one?
Then this is the choice for you.
With pure bulk DMAA, or with DMHA, you can turn any pre workout into a potent one.
It's the one and only as no other vendor sells exotic stimulants like this.
Use a milligram scale like this one because the 5mg scoop it comes with is basically useless, the powder can clump up, and with something as strong as DMAA, you need to be as precise as possible.
Now with DMAA, you can take anywhere from 20mg to 75mg (safely, without elevating blood pressure) and you'll feel the effects elevate around 60 minutes after consuming.
It'll last for 4 hours, and you'll feel an increase of energy, stronger than caffeine of course, and along with that you'll feel more motivation, clear minded and stimulated.
This is a good chance to buy DMAA in bulk so you can have it in storage for a long time, and you can turn any boring pre workout into an exotic one with this.
For example, this 8 stimulant containing pre workout, Rage Reloaded would be great with about 50-70mg DMAA or 200mg DMHA.
Just remember to be safe and use a milligram scale.
Strongest Pre Workouts with Exotic Stimulants in 2021
If you like Eria Jarensis, then you'll like Flame.
You've never seen this much eria jarensis before and it leads to some potent euphoria.
Dark Labs makes insanely strong pre workouts and they've been successfully bringing the heat by creating potent formulas.
Flame is one of the pre workouts offered by Dark Labs and it's a strong formula that is powered by dosages that we haven't seen before.
It's packed with 500mg eria jarensis, a mood enhancing pea variant that can work well especially when it's combined with other stimulants.
In Flame, it's combines a few hard hitting stimulants like 400mg caffeine, 300mg DMHA, 300mg Theobroma cacao extract, and much more.
Although it isn't marketed as a fat burner it would compete well because it has 75mg hordenine, 25mg naringin and 1.5mg alpha yohimbine.
Pumps and endurance are not forgotten thanks to the big 1g dose of creatinol-o-phosphate (COP) and 1g agmatine.
Creatinol is great for muscular endurance and it's highly underrated but that's because there's few to no studies based on it.
However we're a fan of this ingredient so we can't complain.
As with all Dark Labs products, this is fully dosed and is super potent.
This is easily one of the best pre workouts for mood and energy support.
Flame is a limited edition pre workout so if you see it, buy it!

When it comes to aggressive pre workouts, there are rarely any that come to mind.
However, ReviewBros and Huge have formulated Wrecked Extreme to be one of the most urgency-driving pre workouts to date.
It contains over a gram of stimulants, tons of ergogenic aids and doesn't fall short on focus.
The mix of stimulants ensure 3 different levels of varying energy, from slow to medium to super fast.
So the energy is going to drive you from all levels and angles.
And although this is a stim-focused pre workout, the pumps are still there and they are quite good.
The mood enhancement and cognitive function will help you move forward and grind towards your goals.
Shortly after drinking this, you'll feel a sense of urgency kicking in that comes with a bit of aggression, but in a good way.
Wrecked Extreme is one of the best pre workouts to make you want to run to the gym and lift iron.

El Jefe is a sweet name for a pre workout, but that's not why it's here.
This pre workout contains all kinds of ergogenic aids, nitric oxide boosters, and stimulants to help power you through not only your workouts but also your days.
El Jefe is strong.
The citrulline malate combination with 4g beta alanine, betaine anhydrous, taurine and 1.5g Nitrosigine will lead to some nasty pumps.
And on top of that, there's 150mg ElevATP, to help with ATP production.
Also, there's 8 stimulants in here, including DMHA and Eria Jarensis.
While these are in a prop blend, we have tried this pre workout and it's definitely properly dosed.
It's on par with other high DMHA and eria jarensis pre workouts.
It would be a nasty stack if you used ASC nitric oxide booster, which can be found here.
Or if you wanted to add some strong non-stimulant thermogenic ingredients, you can add their Caliente.
Check out our El Jefe review here.
El Jefe on it's own is a very strong pre workout with some nice nitric oxide boosters, but combined with Sicario, especially the limited time edition would be the ultimate pre workout stack.

If you're looking for a pre workout that makes you feel happy, then Pre Phase K.O. is the one to go to.
It has strong energy, with 350mg caffeine and exotic stimulants combined with other energy boosters, this is no doubt one of the stronger ones.
But it's main advantage over other pre workouts is that it can put your mind in a motivational and feel-good state, where you believe you can workout your best but at the same time without experiencing the jitters or anxiety that come with high stim pre workouts.
The DMHA part of it is probably what leads to some of it's urgency, and there's a few stimulants which combine to make a fairly good pre workout for energy and focus.
The only downside is that the tyrosine is dosed strangely at only 200mg but other than that it's a great pre workout for it's ability to increase and uplift the mood.

Although it doesn't have any exotic stimulants, it is easily one of the most potent we've seen and it's topped off with high quality nitric oxide and nootropic compounds.
From the things you wouldn't expect, like 2 forms of caffeine, to a huge 7g dose of citrulline, 3.5g beta alanine, 2.5g betaine and more.
While this has eria jarensis, that's as far as it'll go in terms of exotic stims.
Its stimulant blend contains a few stims, including 650mg caffeine and 300mg theobromine.
These 2 ingredients, along with the nootropics and ergogenic aids have very strong mental supporting benefits.
The big 200mg dose of di-caffeine malate will help prolong these effects, along with the benefit of making the stimulants last longer.
For nitric oxide it has 7g citrulline, 2.5g betaine anhydrous and 1.5g agmatine.
Hooligan is easily one of the best pre workouts for all around energy, pumps and mood support.
But what if you could have both?
If you want both in one pre workout, check out this this pre workout here.
Use discount code FITFREK for Hooligan.
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.

Update: Crack Gold is completely out of stock until end of May or sometime in June.
This is going to be hard to get…
You can still get the original Crack, which has more nitric oxide boosters along with 120mg DMAA.
If the Gold Edition returns, we'll update the link.
The regular version still has 120mg DMAA, along with very strong nitric oxide boosters while the Gold Edition has both DMHA and DMAA.
Gold Edition of Crack is literally the same exact formula as the limited edition.
You get the same DMHA, DMAA and eria jarensis combination for some stim-junkie level energy.
The limited edition of this pre workout had 200mg DMHA, 100mg DMAA and 300mg eria jarensis, which is the same as the Gold Edition.
And also Flame, a DMHA only pre workout with 500mg Eria Jarensis is more focused for mood and smooth energy rather than the harsh energy that Crack has.
Crack is one of the strongest pre workouts we’ve seen yet.
You couldn’t ask for something better…
With 2 strong nitric oxide boosters, along with hard hitting stimulants, you're looking at one of the strongest pre workouts on the market.
But something to be aware of is that DMAA has a bit of a risk for elevating blood pressure when using 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.
There's some nitric oxide ingredients so you'll feel some nice pumps.
It includes citrulline malate, and agmatine.
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 ok but this is mainly a strong energy DMAA pre workout.
You can take half a scoop and you'll still get enough of every ingredient.
If you want to turn Crack into a thermogenic one, try adding Caliente to it, as it's a strong non-stim thermogenic that'll make you sweat.

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.
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!
Be 100% careful and start with half a scoop.
Do not take a full serving no matter how experienced you are with stimulants.

This is not one we like to recommend because of it's high price but it works and it has focus and energy similar to Excelsior.
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, which you'll find below.
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.
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 focus and energy that the original Craze had.
No we're not referring to the reformulated versions like Craze V2, or CRZ OG.
We're talking about the original Craze. The OG.
Excelsior has similar euphoric feels 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.
And the appetite suppression is incredibly strong.
Pizza will no longer be appealing, and forget craving for junk food.
You'll probably forget to eat.
There's definitely something more than the ingredient label shows.
The feeling is sort of like an amphetamine type feel, with a ton of focus and speedy feeling to it.
There's a bit of a mood uplift, but there's also a crash after a few hours.
I wouldn't take this more than once a month because honestly it's strong in effects and I don't think it's worth risking my well-being
Expect to pay around 50 (or about 60-70 if you're outside the US)
That's around $1.5 per serving.
It's worth it for some feel good energy and motivation.
But if you're prone to depression, you may want to look for another pre workout because once you've used a lot of Excelsior, you'll be going through some nasty withdrawals.
This is why you should limit usage or not use it at all if you know you can't help it.
It's available worldwide, throughout the UK and the US.
Try Excelsior and look no further, before you find this Craze replacement gone.
(If you're from the UK or live near it, check it out in this UK store)
Or alternatively you can get it from MusclePlayers.
If you're prone to depression, I recommend trying something else as this may have a strong crash after a few hours.
This is only for experienced users who know what they are doing.
If you're ordering this in April 2021 and beyond, you're getting a fresh batch.
It may be the same exact feeling or it may be altered in a way.
Pre Workout Buying Guide
A strong pre workout isn't always ideal.
Bodybuilders will often go for a stim-free pre workout so they can workout for hours without the dreaded crash or blood constriction of stimulants.
The roller coaster of energy is not worth the withdrawals…
So this here is a serious matter.
Most people will happily go day to day, survive their hectic and stressful lives with stress inducing stimulants.
Those stress inducing stimulants will have your heart pumping harder than ever, your stress levels will be higher and you'd certainly be sleep deprived.
Now for us bodybuilders, our lives are already full of stress already and though training has us feeling happy, we're not allowing our bodies to get full REM sleep cycles.
So when it comes to cycling supplements, you should most certainly be cycling pre workouts (with stimulants).
Magnesium can potentiate the effects of caffeine (and other drugs) it's a NMDA antagonist.
Pre Workout Ingredients
These are the most important ingredients in strong pre workouts that support mood, motivation and energy.
Caffeine is one of the most proven and researched stimulants in pre workouts.
It's a common ingredient and it's the driving force behind any pre workout that isn't stim-free.
Research has also found caffeine to increase metabolism and suppress appetite. 
Any dose from 40 to 300mg can improve mental function, while doses higher than 200mg will enhance physical function. 
Typically research recommends anywhere from 5mg to 6mg per kg of bodyweight can increase performance.
That's about 380mg of caffeine for someone who weighs 165lbs. 
The normal form of caffeine is quick to digest but there's also other forms that vary in speed.
Caffeine citrate is suppose to be faster acting than regular caffeine, while caffeine malate is the slowest digesting.
Typically pre workouts will have multiple forms of caffeine to ensure a steady flow of fast and slow digesting energy.
We have an entire guide on DMAA here.
This is a stimulant that's suppose to be banned but it's still widely available on the market.
As of 2021, Dark Energy and Static Labz is completely discontinued as it's rumored that they've been raided by the FDA.
DMAA is known as 1,3-Dimethylamylamine, and it's an extract of geranium.
It's a stimulant that's commonly used in strong pre workouts.
It's been promoted and marketed as a fat burning ingredient but the energy effects are where this stimulant shines.
How it works exactly is unknown but it's understood that it imitates adrenaline and can increase dopamine production. 
DMHA is known as 2-aminoisoheptane and it belongs to a class of aliphatic amines.
Sometimes it's labelled as plain DMHA, but there's really 2 forms of this stimulant and that's 2-amino-5-methylheptane and 2-amino-6-methylheptane.
The euphoric form leans more on the side of 2-amino-5 while 2-amino-6-methylheptane is provides aggressive energy.
This is still a fairly new stimulant but the accepted dose is anywhere from 100-150mg, while some pre workouts go as high as 200-300mg.
Eria jarensis is a PEA-based ingredient that's standardized to the constituent n-phenethyl dimethylamine (n-methyl-pea)
It functions as a potent neuromodulator and it provides some nice smooth but strong euphoria.
Doses can vary from 150 to 200mg but some pre workouts have gone as high as 500mg.
Again there isn't enough research to state a safe dosage.
Tyrosine is a precursor to the most important neurotransmitters like dopamine, epinephrine, and norepinephrine) 
This ingredient is important to have for maximum energy which is why it's often used alongside caffeine since caffeine can release these neurotransmitters and tyrosine can help produce them. 
What's The Best Replacement For Craze?
We've found a pre workout that just may replace Craze.
You can see it here.
After years of searching and going through many pre workouts…
None of them ever came close, not even Driven Sport's latest Frenzy (and forget about Craze V2)
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 for the best alternative for Craze.
It definitely has something that's not listed on the profile.
Pre Workouts We Don't Recommend:
Our least favorite (the worst you can get), are 4 Gauge (laughable dosages) and Yeah Buddy (sorry Ronnie, but this is just caffeine with everything else being under dosed).
Ronnie's Yeah Buddy is better than 4 Gauge, but it still could use a few major tweaks, and it would probably be better the better choice compared to a cup of coffee.
You're better off making your own pre workout than buying those.
Should You Cycle Stimulants?
Most certainly yes.
Remember the first time you took your first pre workout?
Maybe it barely had stimulants, but it certainly had you jumping from one set to the next with barely any rest.
And after months and months of sipping on pwo's, you've got yourself asking…
“Why isn't it working as well as it did the first time? Should I be switching pre workouts?”
And there begins the hardcore stim user who is soon asking what's stronger than Mr. Hyde and why C4 is the worst pre out there.
Tolerance. It ain't pretty.
Most people don't read into the labels of pre workouts but they clearly state “do not use more than 4-6 weeks”.
They don't mean don't use “Mr Hyde” for more than 4-6 weeks, they mean lay off the stims!
What happens when you need more than 300mg of caffeine?
It's just not sustainable…
How Should You Start Cycling?
A simple 1 to 2 week off stimulants will have you feeling amped when you have your pre workout again.
It takes 24 to 48 hours for the withdrawals to start, and it hits its peak at around 4 days.
So really if you only take your pre workout 2-3 times a week, and assuming it's got moderate stimulants (less than 300mg of caffeine and less than 50mg of other stimulants generally), you should be okay for up to 8 weeks.
But if you're taking stim-heavy pre workouts 3-4 times a week with coffee / other stimulants and haven't taken a break for more than 4 weeks, then it's truly time to take a 1-2 week break.
This really needs an article on it's own as this is general advice.
Bottom line is if you want your pre workouts to hit hard for those demanding workouts, then you need to use those pre workouts only for those sessions.
Try using a stim-free pre workout as that will still have strong performance enhancing ingredients.
You can still use a bit of caffeine (50mg to 150mg) if you're truly sluggish without it.
These types of pre workouts will always have their place in the industry.
But I can see a shift from caffeine to other stimulants.
Caffeine is overrated.
And Craze (though possibly contained a type of amphetamine) and many other pre workouts has proved that it's possible to have a potent pre workout without a reliance on caffeine.
Check out the best pre workouts for muscle gains if you're sick of stimmed up pre workouts.
Leave a comment below, let me know what you think of these pre workouts or if I missed any…
Remember to take basic supplements like ZMA and creatine to make the most out of these.
Can I Stack Pre Workouts?
You can stack any pre workout with any stimulant-free (no caffeine) nitric oxide supplement (See our nitric oxide buying guide).
Are These Pre Workouts Optimal?
Yes and no.
The strongest pre workout isn't always optimal.
Studies have shown 300mg of caffeine being the best dose for performance, there's little research on exotic stimulants that are mixed together like these.
How much you can handle should be assessed by taking half or less the recommended servings.
More is not always better.
Advanced bodybuilders may avoid these heavy stimulant pre workouts.
They'd opt for non-stimulant pre workouts as they wont constrict blood flow as much as these hard hitting pre workouts.
Imagine trying to do 350lb squats with your heart already pounding from taking a heavy cocktail of stimulants?
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.
You don't want to be a slave for stimulants.
My advice: don't use them more than 3 times (4 max) a week or don't take them for longer than 6-8 weeks without taking 2-3 weeks off them.
Get another pre workout with none to moderate stimulants like Transparent Labs Bulk or any pre workout with less than 300mg caffeine.
Because once you go off these hard hitters, you'll feel so drained and tired that you'll feel completely useless on the days that you don't take these.
You won't even be able to do basic functions, let alone workouts.
Limit your caffeine sources.
You don't want to have your usual cup of coffee when you take a pre workout.
What About Pre Workouts For Women?
If you're wondering where our “best pre workouts for women” are, well you're already looking at the right list.
There's no such thing as a pre workout for women.
Would Starbucks label a cup of coffee for women / men?
What about protein powders?
Is there something special in pre workouts that make it only men can use? If so, why wouldn't it say it's for men only?
If you can handle 300mg caffeine along with DMAA and / or other stimulants (check out our DMAA top 10 list here) and then you're fine with any of these pre workouts.
You should always assess your tolerance with less then half a scoop before you take a full serving of any pre workout.
You may even benefit from just taking half servings throughout the entire bottle.
So ladies, forget the color of the bottle, don't fall for the pink labels and flashy marketing.
Just get anything that you can handle, and test it out with half a serving or even less.
What Pre Workout Has The Highest Caffeine?
So far, Hooligan has the highest at 650mg, but that may change soon when Assassin v7 comes out.
What's The Best Pre Workout for Bodybuilders?
Bodybuilders typically need something for muscle building and motivation.
What's The Best Pre Workout for Powerlifters?
Which pre workouts have been banned?
A few years back, the FDA banned Jack3d.
Then came the ban wave on DMAA around 2017, with the FDA mostly targeting Hi-Tech Pharmaceuticals and Blackstone Labs.
Now in 2021, Dark Energy and Static Labz has been raided and DMAA may be in danger.
More DMAA products may go off the market in 2021.
Why is Caffeine Always the Primary Stimulant?
Caffeine promotes wakefulness and improves performance like no other stimulant as it's been proven time and time again for it's usefulness.
This is why it's combined with other stimulants.
Can I take pre workout on full stomach?
No we recommend waiting at least 1-2 hours after eating (depending on the meal size) before taking a pre workout.
The ingredients are best absorbed on an empty stomach.
Can I use The Strongest Pre Workouts For Cardio?
Yes but it wouldn't be optimal. You don't want your heart racing 100 beats per minute before you even start your cardio session.
So taking a quarter scoop or a regular pre workout with just caffeine would be better.
What's The Strongest Muscle Builders?
However if you're looking for something hardcore, check out these lists:
Muscle Building Supplements
We don't recommend using these hardcore muscle builders if you're a beginner, or if you're under 22 years old.
These types of pre workouts are more than enough to give you an advantage for gains with a properly designed program.
We're not saying these will 100% work for you. But these are just buying guides with recommendations.
Even creatine, a well researched supplement, doesn't work for some people.
