Strongest Pre Workouts of 2019
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.
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.
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.
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”.
Best Pre Workouts For Women...?
Tunnel Vision Enhancing Pre Workouts
We're usually not one for hype but this is a pre workout that may actually stand a chance against Mesomorph and it doesn't even have DMAA.
DVST8 Crimson is a powerful pre workout that packs not only 400mg of caffeine, but DMHA and a whole bunch of nootropics as well.
It contains choline bitartrate and huperzine A that will give you a punch in assisting with laser-like focus.
It also contains citrulline malate, betaine anhydrous and l-taurine for further muscle volumization and growth.

Arez has made quite a name for itself with several strong pre-workouts based on the Arez name.
One’s things for sure, when you think about strong pre-workouts with a heavy emphasis on focus and energy, this is a name that comes to mind!
The most recent version is Arez Titanium God of the Gym and it’s not fooling around!
This version means business and it’s heavy on energy, mood and tunnel vision focus.
A big plus is the fully disclosed label which starts off with a somewhat under-dosed pump complex consisting of just 2 ingredients - 3 grams of pure citrulline, and 500 mg of agmatine.
While there’s also a clinically dosed 3.2 grams of beta-alanine, this could use another pump enhancer, or higher dosing of the two ingredients it does have if you want Godlike pumps.
Next up is the GODlike Energy Surge complex - and this is where it gets serious!
First up is PEA (or B-PEA) for mood elevation and focus, eria jarensis, another source of PEA that takes mood and focus even farther, and a huge 175 mgs of juglans regia - the natural source of DMHA, which is, of course, much like the artificial version but absorbs much better and gives cleaner energy.
DMHA also enhances cognitive function which includes focus.
Arez isn’t done yet, there’s still synephrine, yohimbine bark, a strong 350 mg of caffeine, which of course is great for energy, alertness, focus as well as performance, and a 250 mg dose of choline, dosed at the low end of the effective range but enough to impact focus and cognitive function.
Finally there’s 10 mg of yet another stimulant – hordenine, dosed low but here nonetheless.
So, yes there’s beta-alanine for endurance and a pump complex, but this is a pre that’s more about extreme energy, laser sharp focus and intense mood elevation.
If focus, mental enhancement and energy is what you’re looking for, this is it!
It’s an OK value, priced at the higher end with 25 servings and 1 scoop per serving, but look at what you get as far as energy, cognitive benefits and tunnel vision focus - enough to make you God of the Gym every time you walk in!

Yes we know, this would be a pricey stack, but hear us out...
Craze V2 has a bit of a unique focus enhancement to it, but other than that, it falls short in every department.
When combined with a pre workout that increases aggression and energy like Frenzy, you'll find yourself in a fearless-like state with a super focused mindset with the purpose of destroying PR's.
It's the closest you'll ever get to an awesome-almost perfect pre workout
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.

I Am Suprem3 is a masterpiece of a pre workout from Olympus Labs that uses the more expensive form of DMHA (2-amino-5-methylheptane) that is a bit stronger and more expensive than the commonly used 2-amino-6 form.
With DMHA, caffeine paired with Eria Jarensis and ST1M-X you're not only going to be enhanced with motivation and energy but you'll also be in a zone of focus that is nearly unmatched by most pre workouts to this day.
On top of that, it has full doses of nitric oxide boosters so you'll be pumped and full while being energized by the number of stimulants in here.
The crash here is very subtle, and with the focus lasting so long (4-6 hours) you will benefit from this if you have anything that needs focus after your workout.
Overall, I Am Suprem3 is amazingly made so try it if you haven't yet!

Finally, a pre workout that we've all been asking for...
Hydrazine doesn't only have a caffeine-focused formula but it is well rounded with different ingredients to enhance focus and mental clarity.
Now the ingredients in here aren't exactly what you'd want in the ideal pre workout (like Pre-Kaged or Altius) but they are certainly strange and work to what Hydrapharm claims.
Don't take my word for it though, check out these reviews (click on the gray box below to reveal the reviews)...

This has the same exact focus and energy that the original Craze had!
If you're looking for the next best pre workout to replace Craze, look no further.
No we're not referring to Craze V2, we're talking about the original Craze.
Excelsior has that similar euphoric feel to the original Craze.
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).
While it has DMHA and a few other ingredients, it is nothing like any other product that has similar ingredients.
Now the only reason why this isn't in first place is because of it's price. But considering how Craze was sold for as much as $100 (or even more!), this is a great deal in comparison.
Get Excelsior and look no further, before you find this Craze replacement gone.
Aggressive Pre Workouts
Best Aggressive Pre Workouts
If you know Driven Sports, then you know Craze.
Some say it's the best pre workout that's way ahead of it's time.
Only problem is, they discontinued to it years ago and have released an aggressive pre workout named Rize, recently.
Rize isn't supposed to replace Frenzy but it is in the same category of aggressive energy.
Similar to the original Craze, Rize provides a nice gradual increase in focus and energy, without any sudden spikes or bursts.
The reviews say that the energy lasts around 5 hours, which lines up to what Driven Sports is promising.
The energy is strong, but yet the focus is still there.
So you'll be zoned into your sets with a steady but strong flow of energy.
Don't expect anything to be "clinically dosed", as this is mainly a pre workout for energy.
Stack it with a nitric oxide booster for massive pumps.
It's not meant to be used as a study aid and definitely not on a daily basis.
When you're lifting, you want to be unstoppable.
But to go all out might be a little hard if you don't have the right pre workout.
Truthfully you only need a bit of rage, and a strong mindset to get into the gym with a destructive attitude towards the iron but with the second version of Unstoppable, it makes it a whole lot easier.
The energy that comes from this is strong, but the focus is even better.
It puts you in a very aggressive state of mind.
There's a unique mix of stimulants in here, ranging from 175mg caffeine, 100mg theacrine to thermopsis lanceolata and longan fruit extract.
This unique blend will have you stepping in the gym with your eyes on the iron, with absolutely nothing else on your mind.
The best part is that it contains creatine nitrate, so pumps and vascularity will increase with Mesomorph.
You'll see Mesomorph all over this page.
It doesn't only increase energy, focus and strength but it also gives a bit of aggression by making you feel like you could run through walls (but don't do that).
With 65mg DMAA, 300mg caffeine and a couple of ergogenic ingredients, it's no wonder that this pre workout can do so much from one serving.
What makes Mesomorph different is that it contains creatine nitrate, so pumps and vascularity will increase and continue to work well with each use.
The best part is that the flavors are so diverse and delicious to keep your taste buds satisfied.
There is bad news though as DMAA is possibly discontinued so there will be a different stimulant soon.
Get this while DMAA is still in it!
Nitraflex tries to be something different, something we bodybuilders can always appreciate.
Not only does it have 325 grams of caffeine (equal to 3 scoops of the original Jack3d) but it also has testosterone boosting ingredients.
Nitraflex combines stimulants, nitric oxide and testosterone inducing ingredients.
While we don't know for sure if it actually increases testosterone, we do know it gives a kind of "alpha-feeling" so you'll feel at the top of your physical and mental game.
There's a couple of nitric oxide ingredients in here but everything is in a prop blend, so there's no telling how much of ingredient there is.
They recently redesigned the bottle so they don't use the formal scientific names for the ingredients like they used to.
It’s hard to read the ingredient label, so I’ll translate it for you... (click the ingredients below)

L-citrulline (expensive ingredient)
Obliterate is a pre workout that takes advantages of strong stimulants and packs it into one small 7g scoop.
It doesn't only use DMHA but 2 forms of it, along with 2 forms of caffeine and hordenine to make it all last longer.
This stuff is not to be taken lightly.
Start with a quarter to half a scoop and once you find your sweet spot, you'll find yourself with an aggressive source of energy that'll help you blast through your workout.
DMAA is hard to find, but Centurion Labz seems to have loads of it because God of Rage is almost never out of stock.
Packing 60mg DMAA and a load of stimulants, Rage (also known as God of Rage), is going to have all day energy and focus.
With 1g agmatine, it'll not only help with pumps, but it'll also decrease blood pressure that might be affected from the stimulants here.
Try it at half a scoop before going with a full serving because this is one of the strongest pwo's we've seen.

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.)

Driven Sports is not the most trustworthy company out there and we certainly do not recommend taking this if you're being tested for banned substances.
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 what it offers.
It brings out your inner 18 year old self again with "limitless" aggression and motivation.
It's like Bullnox but it is much stronger.
The energy makes you forget pain, and the aggression makes you remember why you started training.
Frenzy's formula is a laughing stock for us knowledgeable supplement freaks but so was Craze, yet it still did what it claimed.
With 140 reviews and a 96% rating, there’s no way that everyone can be wrong about this pre workout.
A lot of people stack it with Craze V2 because it somehow enhances the focus.

High Energy With DMHA
Broken Arrow was made for hardcore stim users only - and it’s easy to see why!
One look at the fully disclosed label and even though it has some good ingredients to cover the pump, extend endurance and improve performance, it seems to be more about energy and mood elevation.
However, the other thing you may notice is that several ingredients are under-dosed.
It starts off great with 6 grams of citrulline malate, the full clinical dose, and a solid 1 gram dose of taurine for pumps – and those two ingredients may be enough, but we’d like to see a more serious pump complex.
Then there’s betaine, which is a great strength and power enhancer that’s similar to and synergistic with creatine, in fact this is an effective ingredient that should be utilized in more pre-workouts, so we’re happy to see it in Broken Arrow, but it’s under-dosed at only 1.5 grams (it should be at least a gram higher).
However, the well-known fatigue blocker/endurance ingredient, beta-alanine, is correctly dosed at 3.2 grams. So, for pumps and performance, Broken Arrow will get the job done, but it could have hit much harder.
What about the stim/cognitive ingredients?
We have an effective 1-gram dose of tyrosine that works synergistically with a potent 350 mg of caffeine.
Next, we have a low dose (300 mg) of alpha GPC for mood elevation and mental stamina.
Standard dosing on this can go as high as 1200 mg. Finally, there’s the potent stimulant/focus ingredient DMHA with an effective 150 mg dose.
DMHA has numerous benefits, including energy and focus, it also stimulates production of the hormones dopamine and noradrenaline, the “feel-good” hormones.
Overall, Broken Arrow is a little disappointing, just when you think you’ve got a well-rounded hardcore pre-workout, you have several under-dosed ingredients.
To be clear – it will provide very good energy, focus and mood elevation, but it could have been even better with a higher dose of alpha GPC.
It’s not bad for pumps and performance – but it could have been even better with more betaine and one or two more pump ingredients.
As far as value, it’s priced a little on the high end with 30 1-scoop servings.
This pre-workout needs a few adjustments to be a home run winner, right now, it’s falling a little bit short.

If you've heard of DVST8 then you'll know they mean business.
With their latest pre workout, Crimson, it's probably going to blow a lot of people away.
It contains 400mg caffeine, DMHA, and a bunch of nootropics.
Even if you're stim-tolerant, you'll want to start at half a scoop as it tops more than 300mg of caffeine with DMHA and a few other stims.
If you don't feel like jumping off walls after taking this one, then you should consider taking a super long stimulant break.

Any company that has "Labz" in it is usually suspect to underdosed prop blends, but Centurion Labz is an exception.
They're not only using fully disclosed labels, but most ingredients are decently dosed.
Aside from the microdose of choline and huperzine, the ingredients dosed here are quite good and will provide lots of energy and focus.
It has Eria Jarensis for mood enhancement and 200mg of DMHA for long lasting energy.
Jitters and anxiety will probably non-existent as caffeine is moderately dosed at 250mg and there is no yohimbine.

If you're looking for mood enhancement and euphoria, Excelsior has it.
Though it has DMHA and a couple of stimulants, the effects are unlike any pre workouts we've had since the original Craze days.
This pre workout is the closest to Craze, and it effects are identical.
This and Hydrazine are both amazing pre workouts that provide all-day focus and energy.
In fact, you won't want to take this after 12 pm or you'll struggle to sleep before 12 am!
The price never ever drops, so get it before you find it discontinued.
Start at half a scoop, and in fact you may get away with using a little less than a full scoop throughout the entire tub.
If you like DMHA then you will surely want to try this pre workout.
Convict is packed with 225mg of the hard hitting stuff and packs a mean formula that’ll get you rocking and motivated.
It isn’t only packed with stimulants though, it also has properly dosed ergogenics as well such as 4g citrulline, 2.5g beta alanine and more.
Everything in here will surely enhance your performance from the first set to the last.
If you’re looking for a hard hitting pre workout, Convict is one to try.
Update: V5 is coming out and it adds even more stimulants like theobromine and 50mg hordenine, but this current version is already epic!
If 300mg DMHA and 600mg caffeine is more than enough for you, then you've found your match with Assassin.
This pre workout by Apollon Labs is an epic formula that uses all kinds of stimulants and ingredients for energy and long lasting focus.
It isn't made for beginners nor should anyone start with a full serving even if you've been using pre workouts for 10+ years.
We've never seen a pre workout that comes close to this, it will probably be too much for most people.
If you know what you're dealing with and like it, then it is probably a dream come true for you.
One scoop will be enough for energy and pumps, and even outperforms most pre workouts at one scoop!

High Energy With Ephedra
Ephedra is some strong stuff when it comes to energy and thermogenic effects.
Here we have the best stuff with ephedra...
Ain't it nice when something this strong comes in a tiny capsule?
Hellfire is something that is as strong as it appears and it's appropriately named.
This powerful fat burner is designed to turn up the heat in your body, while increasing energy and focus like never before.
Its 235mg blend of strong stimulants will get you in the zone fairly quickly.
All of these doses are in one single doses and Innovative Labs warn that should not take more than 3 capsules in a 24 period.
In fact, you'll be perfectly hyped with 1 capsule, maybe 2 but anymore than that and you'll just be anxious and jittery.
Pop one of these capsules either with or without a nitric oxide supplement (perfect as most N.O. supplements don't have caffeine) and you'll have a pre workout stack better than 99% of the stuff out there.
Strongest Pill Form Pre Workouts
Sometimes you just need the convenience right?
Pill form pre workouts are almost always as effective as the powders, but usually contain only a few ergonomic ingredients and mostly stims (pills can only fit so much).
Check our DMAA page for more of these types of fat burners and pre workouts.
So let's jump right to it...
Arsyn is a serious energizer/ fat burner that’s loaded with energizers and mood enhancers.
Since it’s marketed as a fat burner, it also includes thermogenics and targeted “stubborn fat” ingredients.
The full disclosure labeling is a big plus, now if everybody else would catch the hint!
Even though Arsyn is an effective fat burner, you can use it as a pre-workout because of the energy, focus and cognitive benefits it provides.
Sure, there’s no pump or performance ingredients but you can stack it with a stim-free pre-workout and get a great training experience.
The stim/cognitive complex starts with tyrosine ( a little under-dosed), caffeine (well dosed at 300 mg), DMHA (good dose and great energy), noopept (very well dosed), synephrine (dosed low), higenamine, hordenine and huperzine all well dosed.
The combination of caffeine, noopept and DMHA will get you fired up for a great workout!
In fact, as far as DMHA, this is dosed higher than many other products we’ve seen.
It’s one of the highest doses we’ve seen.
DMHA is a powerful energizer that will also increase focus, enhance mood, and yes, it’s involved in fat loss as well.
As a pre-workout, this will definitely get you ramped up and ready to hit your toughest workouts - stack it with some pump boosters and, say, betaine along with beta-alanine and you have a great pre-workout.
Arsyn is a decent value with 60 2-capsule servings per container - a 30 day supply.
The name Arsyn fits, as a fat burner it does exactly what it says, and as a pre-workout, it’ll get you just as fired up.
Rocket Fuel has the perfect name for its effectiveness, it contains 5 stimulants to rocket you through your workout and some more.
This is a 395 mg prop blend (yep, another under-dosed prop blend), so we’ll get right to the point – the suggested max dose of Rocket Fuel is 3 capsules over the course of the day, and you will need to take two at once if you want to get reasonable dosing.
We don’t know how much caffeine is in Rocket Fuel, but that is what starts off this formula.
DMHA is a potent stimulant, mood and focus enhancer as well as effective fat loss compound. Oleuropein is an olive leaf extract that helps prevent the body from producing more fat cells than it already has.
Orchilean is an adaptogen that helps increase the natural energy of the body, and eria jarensis is a mood enhancer and is similar to ephedra in its energy effects.
As a pre-workout, you’ll experience a ton of energy, focus, and motivation that will power you through your training session.
For a more well-rounded experience, stack this with your favorite stim-free pump and performance pre-workout.
A plus with this product is it’s a 90 capsule container that’s very well priced, so even if you use it at full strength, that’s a 30 day supply and it’s still priced right.
King Cobra used to be Blackstone's strongest fat burner, now they've replaced it with ViperX.
What's unique about ViperX is it's formula, we've never seen some of the ingredients before.
Achyranthes Aspera for one, which is a potent Ayurvedic herb, it basically controls blood sugar levels, appetite and speeds up digestion.
It'll not only enhance energy but also mood, thanks to the nice 100mg dose of Eria Jarensis.
No matter how strict your diet is, your mood and energy will be elevated with ViperX.
Overall this fat burner will hit hard with it's various simulants.
ViperX is not only available in a pill version but also a powder version.

Hydrazine is literally one of the best pre workout's out there.
It's often compared to the OG Craze and we've heard, but not confirmed, that Hydrapharm has a pretty tight relationship with Driven Sports, which isn't surprising to us!
Now you don't want to depend your health on this but if you're on this strongest pre workout list, you probably don't care much anyway.
This formula, like Frenzy and Craze, doesn't depend solely on caffeine for energy.
