Flame by Dark Labs

on mysuppplug
500mg Eria Jarensis, 300mg Theobroma Cacao Extract, 300mg Caffeine, 300mg DMHA, 100mg Caffeine Citrate, 1g Agmatine, 1g Creatinol-O-Phosphate, 10mg Black Pepper Extract

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.

Herolean being one of them.

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!

The "Russian" Power Pre Workout

on nutritionalsupplementshop
Citrulline, Beta Alanine, Agmatine, Caffeine, DMHA, Eria Jarensis, Hordenine, Alpha Yohimbine, L Tyrosine, L-Dopa, L-Phenylalanine, Theobromine, N-Acetyl-L-Carnitine HCL, Alpha GPC, Phosphatidyl Serine, Bacopa Monniera Leaf Extract

When it comes to aggressive pre workouts, there are barely any that come to mind.

Urgency and focus is what The "Russian" Power delivers.  

Although it's made with a big proprietary blend but it's a strong pre workout.

The mix of stimulants provides various levels of energy and focus, from hard hitters to slow ones. 

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 good.

The mood enhancement and cognitive function will help you move forward and grind with full force. 

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.

The "Russian" Power pre workout is one of the best for it's urgency-like energy and strong focus

There are no side effects, and it lasts for hours. 

In fact, after about 5-6 hours, you'll still feel fully energized and focused.

El Jefe LTD by ASC Supplements

on nutricartel
Caffeine, Caffeine Citrate, Theobromine, Eria Jarensis Extract, DMHA, Caffeine Malate, Higenamine HCl, Alpha Yohimbine, Hordenine, 7g Citrulline Malate, 4g Beta Alanine, 2.5g Betaine Anhydrous, 2g Taurine, 1.5g Nitrosigine, (150mg ElevATP)* (Choline Bitartrate)*,  DMAE Bitartrate, Yohimbine HCL, Halostachine, 10mg Black Pepper Extract (*= only in the regular version, and not in the LTD version)

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.

Phenta Plex by ABL Pharma

400mg Caffeine, 100mg Synephrine, 100mg DMHA, 100mg Eleuthero Root Extract, 30mg Niacin, 5550mg Proprietary Blend

Update (23/12/21): Unfortunately, ABL Pharma is no longer supplying online stores with Phenta Plex. They want this pre workout to be sold locally only, for whatever reason. Whatever you find now from the online stores is what's left. Once it's gone, who knows when it'll be back. 

I've tried 4 bottles so far, and Sour Candy seemed to be the worst for effects. I've had Blue Raspberry, Fruit Punch (2), Sour Candy (1 out of 2), and Strawberry Lemonade which all provided my original experience. Strangely, the other sour candy bottle didn't seem to have the same ingredient or something.

I've had If there's one thing that you may have noticed is that Excelsior is expensive. 

And hard to find.

The price has never dropped for Excelsior, it's always been $59.99 or higher but now you'll find it for at least $100.

There's a new Excelsior replacement on the market and it's much smoother with strong focus. 

It's Phenta Plex. 

The effects lasts longer than 10 hours at a time. 

Even at the end of the day, you'll still feel wired, tunnel vision and overall a uplifted mood, no matter how early you take it. 

Tunnel vision focus is a sure thing with Phenta Plex, unlike Excelsior, it's much easier to breathe without any signs of anxiety. 

Here's my review on it.

Overall, Phenta Plex is a much cleaner feeling pre workout than Excelsior and it doesn't ruin appetite or cause nausea. 

It makes you feel much lighter, creating a feeling of "limitless endurance". 

It's just much easier to breathe while using it.

And it's energy is strong, long lasting, without a crash or any signs of mood swings.

Double Impact v2 By Apollon Nutrition


7g citrulline, 3.5g beta alanine, 2.5g betaine anhydrous, 2g tyrosine, 1.5g agmatine sulfate, 1g lion's mane extract, 600mg alpha GPC, 300mg Himalayan Pink Salt, 300mg Rhodiola Rosea Extract, 150mg elevATP, 50mg AstraGin, 30mg Noopept

500mg Beta Phenylethylamine HCl, 450mg Caffeine Anhydrous, 300mg Eria Jarensis, 300mg Juglans Regia Extract (DMHA), 300mg Theobromine, 200mg Di-Caffeine Malate, 75mg Hordenine HCl

When Double Impact v1 released a few months, it was one of the strongest pre workouts around.

But the problem was, it didn't last long and it was sort of pricey.

This is Double Impact v2, it's also sort of pricey, but with the discount code FITFREK, you can bring the price down to $55.

Compared to other pre workouts, Double Impact v2 is a complete pre workout with performance enhancers, stimulants and nootropics.

Even if you take half a scoop, you would be getting more than your average pre workout.

Each scoop is packed with 650mg caffeine, 300mg DMHA, 300mg eria jarensis and much more.

There are 7 stimulants, and more than 10 performance enhancers.

If you find a pre workout that has more than Double Impact v2, you just won't!

And also, this is probably another limited run pre workout knowing Apollon Nutrition, so if you want to try out Double Impact jump on this soon.

Original Crack & Crack Reloaded by Dark Labs

6g citrulline malate, 3.2g beta alanine, 1g choline bitartrate, 1g agmatine sulfate, 1g lion's mane, 600mg alpha gpc 50%, 100mcg huperzia serrata

500mg beta-phenylethylamine, 500mg eria jarensis, 350mg caffeine, 150mg caffeine citrate, 100mg dicaffeine malate, 100mg theobromine HCL, 50mg isopropylnorsynephrine, 30mg noopept, 2mg alpha yohimbine,

Crack Reloaded is the first of it's kind from Dark Labs.

It doesn't have DMHA or DMAA, but yet it rocks 500mg eria jarensis, a load of stims and lots of energy to spare.

The focus is absolutely incredible, and the formula is well built together. 

Check out my review here.

And my video review can be found here

It's full of stimulants, but it also hasn't forgotten about pumps as it has 6g citrulline malate and a full gram of agmatine sulfate.

While Crack Reloaded sounds like another reloaded and rehashed pre workout, it's not. 

When has Dark Labs disappointed anyone?

Crack Reloaded:

  • 6g citrulline malate, 3.2g beta alanine, 1g choline bitartrate, 1g agmatine sulfate, 1g lion's mane, 600mg alpha GPC 50%, 500mg beta-phenylethylamine, 500mg eria jarensis, 350mg caffeine, 150mg caffeine citrate, 100mg DiCaffeine malate, 100mg theobromine HCL, 50mg isopropylnorsynephrine, 30mg noopept, 2mg alpha yohimbine, 100mcg huperzia serrata

Crack Gold:

  • 5g Citrulline Malate, 2g Beta Alanine, 1g Agmatine, 500mg Alpha GPC, 500mg N-Acetyl L-Tyrosine, 10mg Black Pepper Extract
  • 300mg caffeine anhydrous, 200mg caffeine citrate, 300mg eria jarensis, 200mg DMHA, 100mg DMAA, 50mg hordenine, 25mg naringin, 1mg alpha yohimbine

Crack Original:

  • 8g citrulline malate, 3g beta alanine, 1.5g agmatine sulfate, 1g arginine nitrate, 1g Beet Root Powder, 500mg choline bitartrate, 250mg L-Norvaline, 25mg Sceletium Tortuosum Extract, 15mg Grains of Paradise
  • 400mg caffeine anhydrous, 120mg DMAA

And Dark Labs has other pre workouts.

Like Flame, a DMHA pre workout with 500mg Eria Jarensis is more focused for smooth euphoric energy.

Crack Gold has 2 strong nitric oxide boosters, along with exotic 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 going 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.

Assassin by Apollon Nutrition

500mg phenylethylamine HCl, 450mg caffeine, 300mg DMHA (Juglans Regia Extract), 300mg Eria Jarensis, 200mg Di-Caffeine, 75mg Higenamine, 75mg Hordenine, 2mg Yohimbine HCl, 1.5mg Alpha Yohimbine, 4g Citrulline, 3.5g Beta Alanine, 2.5g Betaine Anhydrous, 2g L-Tyrosine, 1g Agmatine, 1g Lion's Mane, , 300mg Grape Seed Extract, 50mg AstraGin, 2mg Noopept

Assassin v7 is the latest pre workout from Apollon Nutrition.

From the things you wouldn't expect, like 2 forms of caffeine, to a huge 4g dose of citrulline, 3.5g beta alanine, 2.5g betaine and more, Assassin is a monster of a formula.

The stimulant blend contains quite a few stims...

Including 650mg caffeine and 300mg eria jarensis, but it goes beyond caffeine with 300mg DMHA and 500mg Phenylethylamine.

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 4g citrulline, 2.5g betaine anhydrous and 1g agmatine.

In comparison, Hooligan is great if you're looking for solid energy without exotic stimulants, and if you want to go all out, then go with Assassin v7.

And Apollon just keeps coming out with new flavors for this version. 

Recently, a new NutriCartel version just came out, the Cherry Cola version. 

Deciding between Assassin and Hooligan might be a tough choice.

But what if you could have both?

Assassin is meant to be taken for the hardest workouts, whether you're trying to break your PR for compound lifts or lift high volume, like bodybuilding style, this is the perfect pre workout to use.

Assassin is easily one of the best pre workouts for all around energy, pumps and mood support.

The difference between Assassin and Hooligan is that Assassin is more of a stim junkie type of pre workout if you're looking for the strongest energy and focus.

Excelsior by Imperial Nutrition (Hard to get)

on Predator Nutrition
Kigelia Africana Extract (fruit), Caffeine Anhydrous, Bauhinia Purpurea, Bitter Orange Extract (fruit), Octopamine, Hawthorne Extract (fruit), L-Citrulline, Betaine

Update November, 2021 - June, 2022: Excelsior has been out of stock and hard to find due to the FDA putting pressure on them. We will update if it's back in stock. Imperial Nutrition already hyped up its return but it's been months since then. 

But meanwhile we have found something comparable, and maybe even better because it's half the price of Excelsior: check out Phenta Plex.

With Phenta Plex, you'll get crazy strong energy and focus for more than 10 hours at a time. 

You can get Plex from here.

Or check out Power by Badass Labz, which feels much stronger than an actual pre workout with DMHA and caffeine. 

Excelsior can also be found from the UK but it's nearly $100...

Back to Excelsior...

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.

Bulk DMAA by Bulk Stimulants

on bulkstimulants
DMAA (1,3-Dimethylamylamine)

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.

Or you can make your own by buying bulk powders, including caffeine.

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, any of these beginner-friendly pre workouts would be great with about 50-70mg DMAA or 200mg DMHA. 

Just remember to be safe and use a milligram scale. 

Similarly you can get DMHA and eria jarensis from the same store. 

Of course this is only meant for people who know what they are doing and have a measuring scale.

You can't eye out the servings, you need a scale. 

As I've shared in my review, you'll want to use it in pre workouts that don't already have DMAA. 

Enhances mood and euphoria 
Long lasting (140 to 200 servings)
Nice blend of nootropics and stimulants 
Requires scale 

What Are The Strongest Pre Workouts?

To recap, here are the strongest pre workouts...

This is what we think are the best of the best:

These are all pre workouts that have above average amounts of energy, and most of them are monstrous when it comes to dosages.

There are also quite a few pre workouts that didn't make the cut. But if you're looking for pre workouts for sustainable, daily use, then check out this list. 

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).

If you're not already taking your basic supplements like ZMA and creatine, then you might not be making the most out of these pre workouts.

Magnesium can potentiate the effects of caffeine (and other drugs) it's a NMDA antagonist.

Strongest 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.

Caffeine is an energy booster and it can also enhance focus, alertness, and even fat loss. [12]

Research has also found caffeine to increase metabolism and suppress appetite. [3]

Any dose from 40 to 300mg can improve mental function, while doses higher than 200mg will enhance physical function. [4]

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. [5]

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. [6]


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

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) [7]

It can alleviate stress and help you handle stressful situations better. [89

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. [10]


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?

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, and it doesn't have any exotic stimulants or banned (or not approved for WADA) substances. 

What's The Best Pre Workout for Bodybuilders?

Bodybuilders typically need something for muscle building and motivation. 

Something like Hooligan would be great but Wrecked and Bulk are also good choices. 

What's The Best Pre Workout for Powerlifters?

Hooligan again would be great for powerlifters but another great choice would be Wrecked Extreme.

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. 

If you don't like crashes or exotic stimulants, check out either Bulk or Wrecked. (Discount code FITFREK).
