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
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.
Performax Labs HyperMax updates their popular pre-workout to the max!
This innovative brand recently completed a major brand overhaul with a new look and impressive product upgrades, with HyperMax being one of the first products released under the new rebranding effort.
The ingredients are packed!
Originally known as “HyperMax XT”, this is a pre-workout that’s been heavily upgraded, starting with full disclosure labeling and effective dosing.
HyperMax is a maxed out 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 325 mg of caffeine, and that’s supported with 1 gram of tyrosine, which works extremely well when it’s paired with caffeine.
Then there’s 25 mg of synephrine, milder but structurally similar to ephedra, and 3 mg of 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.
This isn’t just a pre workout that’ll get you hyper to the max...
HyperMax hits hard with pumps – with effective dosing of citrulline, agmatine and ornithine, plus beta-alanine for extended endurance.
This is 1 scoop dosing and is competitively priced with 25 servings, bucking the trend used by many pre-workouts, usually advertising 30 1-scoop servings, only to find you need 2 scoops for maximum strength, cutting your 30 servings to 15.

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
Re1gn 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, Re1gn is amazingly made so try it if you haven't yet!

GoldStar has reformulated this pre workout a couple times now and when it was formulated with phenylpiracetam, DMHA and eria jarensis, this was literally the go to for tunnel focus and energy.
Now it is still great for energy and focus, but it is only powered by DMHA and caffeine.
And the entire blend is made into a prop blend, so you don't know how much you're getting of anything, even caffeine but we're guessing caffeine is at around 300-350mg as it was last formula.
So if you try Triple X, start with half a scoop and assess your tolerance.
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)...

Aggressive Pre Workouts
Best Aggressive Pre Workouts
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!
Bullnox (also known as B-NOX) is like the mild version of Frenzy, but gives you more of a anger / frustration feeling.
The long formula is an entire prop blend that is most likely underdosed, it contains ingredients that'll increase endurance and performance.
This could replace your ZMA since it contains it already.
Bullnox (or the newer looking B-NOX) will essentially provide that urge to lift and make you feel like you're about to break a PR or two.
This also contains a testosterone blend but it most likely won't give you as much as a stand alone booster.
Like most pre workouts, it's best used 1-3 times a week for maximum effectiveness or you'll build tolerance quickly.
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)
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.
SRS Wattage Proprietary Blend 4.9G Creatine Monohydrate Taurine L-Citrulline L-Carnitine L-Tartrate 4-Methyl-2-Pentanamine Citrate (Pouchung Tea) (Pentergy) B-Phenylethylamine HCl Tangerine Extract (Citrus Reticulata) (Citramine) Caffeine Anhydrous
Olympus Labs has brought us all kinds of hardcore supplements ranging from test boosters to pre workouts.
Before Re1gn, 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 "Re1gn"!
Giant Doses of Nitric Oxide Boosters
We rarely see this much citrulline being used in any pre workout.
Re1gn 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 Re1gn 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.)

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.
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.
High Energy With DMHA
Olympus Labs has kicked 2016 at an epic start.
They've launched a whole new line of products, and this is their latest pre workout.
Conqu3r Unleashed is the 3rd version Olympus has released so far.
With 5 fully dosed, and patent ingredients, there's no doubt you'll engage in some super intense workouts with this in your arsenal.
Besides a 650mg stimulant complex, it's got 4 ingredients that'll increase your pumps like never before.
Every serving is designed to get you into a super focused state that will help you dominate your workouts like crazy.
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.

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.
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.
Like Craze, it uses an orchid extract called Cymbidium Goeringii, which is suppose to work as an stimulant but there isn't any evidence to back this up.
One cap would be enough but you will surely enjoy two if you're looking for something strong.
The best part is that there virtually is no crash with Hydrazine... So enjoy it while it's not banned and available to the world!
