Updated February 10, 2024

You're here because you want that intense energy boost for your workouts.

With 400mg of caffeine, these pre-workouts are not messing around.

But remember, more caffeine isn't always better.

It's about what works for you.

My go-to? Zeus Pre-Workout.

It's powerful, gives you that clean energy surge, and it's packed with other stimulants to keep you focused.

If you're into serious workouts, Zeus is worth checking out.

Not everyone needs 400mg of caffeine, though.

And if you're a tested athlete, watch out for pre-workouts with exotic stimulants.

For a athlete-approved pre-workout, try something like Pre Kaged Elite.

Below, you'll find a list of the best 400mg caffeine pre-workouts, including options with and without exotic stimulants.

Whether you're looking for that extra kick or something a bit more balanced, there's something here for you.

DMAA & Nitrates

Crack has been the original and best selling pre workout from Dark Labs for years. 

It's a strong pre-workout with DMAA, caffeine, and nitrates. 

This original version contains 400mg caffeine along with 120mg DMAA and quite a few nitric oxide boosters to help with pumps. 

While it has quite a few ingredients that will help with energy and pumps, it still has DMAA which can reduce vasodilation, which is why they included the nitrate ingredients. 

It also has a big dose of citrulline malate at 8 grams, along with 3g beta alanine for tingles, agmatine, and a whole bunch of nitric oxide boosters. 

Many pre workouts of this caliber hasn't lasted this long on the market, and Crack has been selling since it was released in 2019. 

It's one of the most popular pre workouts to date when it comes to DMAA pre workouts but it's also one of the most packed when it comes to pump ingredients. 

We're talking about the 6 nitric oxide-inducing ingredients here which include citrulline malate, agmatine sulfate, arginine nitrate, beet root powder, l-norvaline, and sceletium tortuosum extract. 

You'll probably see many DMAA pre workouts on the market, competition is good to see, but almost everyone will agree that Crack is legit and one of the best you can get. 


Gorilla Mode 

Rounded Pre Workout / Nitric Oxide Hybrid
Gorilla Mode Pre Workout by Gorilla

Gorilla Mode is a pre-workout that's just halfway to being a stim-junkie strong type of pre-workout as it only has eria jarensis without the exotic stim like DMAA or DMHA. This makes it a great choice if you're looking for strong energy without the risky gray area stims.

  • Long-lasting nitric oxide effects
  • Multiple ingredients to increase vasodilation
  • Strong enough to be one of the stronger standard-type of pre workouts
Ingredients: 9g Citrulline, 5g Creatine Monohydrate, 3g Malic Acid, 2.5g Betaine Anhydrous, 1.5g Tyrosine, 1g Agmatine, 500mg Kanna, 10mg Bioperine, 400mcg Huperzine
Stimulants: 350mg Caffeine, 350mg Eria Jarensis
FitFrek earns a commission if you click this link and make a purchase, at no additional cost to you.

Gorilla Mode brings a decent punch but doesn't quite hit the mark of a stim-junkie's dream.

It's packed with 9g Citrulline and 5g Creatine Monohydrate, aiming for muscle endurance and pump.

With 350mg of caffeine, it's on the higher end but lacks the exotic stimulants some might be seeking.

  • Pros: Great for those who prefer a straightforward energy boost without exotic stimulants.
  • Cons: Might not satisfy those looking for the ultimate stimulant experience.

While Gorilla Mode offers a robust formula, it's more of a middle-ground pre-workout.

It's perfect for those who want a significant energy boost without stepping into the more intense territory of DMAA or DMHA.

However, if you're chasing the extreme edge, you might find it lacking.

If you need something with more caffeine, 375mg, then consider Gorilla Energy. 


Zeus Pre Workout

Zeus Pre Workout by God Status Labz

With DMHA, GABA, and more, this is a good replacement for Dark Energy.

If you really wanted to make it like Dark Energy, you could add in your own DMAA from BulkStimulants and it would be exactly the same. Check out our review here.

Nutricartel has two exclusive flavors, Godly Peach & Red Gummy, which you can find here.

SuppsCentral also carries Zeus.

Ingredients: 6g Citrulline Malate, 3.2g Beta Alanine, 2g L-Taurine, 750mg DMAE, 50mg GABA, 50mg Vitamin B6
Stimulants: 400mg Caffeine, 350mg Beta PEA, 200mg Eria Jarensis, 200mg DMHA, 80mg Synephrine
Discount code: FITFREK
FitFrek earns a commission if you click this link and make a purchase, at no additional cost to you.

God Status has been providing us the hardcore pre workouts with exotic stimulants for years now. 

Unfortunately, they were one of the companies that took a hit in 2021 when the FDA confiscated and halted production of many lineups of DMAA pre workouts. 

This is similar to Dark Energy in that it has 400mg caffeine along with 200mg DMHA, and GABA. 

The GABA should provide some enhancements to mood, overall it's a great pre workout that does give some nice mood uplift. 

for serious athletes

Pre-Kaged Elite is one of the few pre-workouts that have set even higher standards for dosing citrulline. 

Elite packs 10,000mg of citrulline, 3.2g beta-alanine, 2.5g betaine anhydrous, and much more. 

There's also a combination of nootropics combined with caffeine and AmaTea. 

While the caffeine doesn't total over 388mg, it's still a great choice, and it's close enough to be a pre-workout with 400mg. 

And this is one of the cleanest pre-workouts you can get if you're a drug-tested athlete. 

It doesn't have any gray area stimulants, nor does it try to go overboard in any area. 

So if you want something reliable, clean and doesn't have any banned substances, then Pre-Kaged Elite is a pretty good choice. 

Guide For Buying Pre Workouts with 400mg Caffeine

The realm of 400mg caffeine pre-workouts is considered "big leagues".

These aren't your average pre-workouts; they're designed for those who crave that extra kick, that surge of energy that pushes you beyond your limits. But tread carefully, for this is a realm not suited to everyone.

Caffeine and Its Effects

Caffeine is a powerful stimulant known to increase alertness, sharpen focus, and delay fatigue.

In the context of a pre-workout, the spark lights the fuse.

But when you're dealing with 400mg, you're dealing with a firecracker.

This is a high dose that commands respect.

It can significantly enhance performance, but it can also lead to side effects like jitters, insomnia, and rapid heart rate if not managed properly.

Who 400mg Pre Workouts Are For

400mg caffeine pre-workouts are for the seasoned, the experienced, and the ones who've been in the trenches and know their limits.

They're for those who've spent years testing their tolerance to stimulants and are now seeking something stronger.

If you're new to pre-workouts or have a low tolerance to caffeine, these products may not be for you.

How to Use 400mg Caffeine Pre-Workouts

When using 400mg of caffeine pre-workouts, timing is everything.

It's recommended to take them 30-45 minutes before your workout. It's also crucial to cycle these pre-workouts to prevent a buildup of tolerance and to give your body a break.

As for dosage, always start with half a serving to assess your tolerance.

Choosing the Right 400mg Caffeine Pre-Workout

When choosing a 400mg caffeine pre-workout, don't just look at the caffeine content.

Consider the other ingredients, the brand's reputation, and the transparency of the ingredient list. Remember, a pre-workout is only as good as the sum of its parts.

Is 400mg Caffeine Enough?

The dose of 400mg caffeine is more than enough for most people.

Some pre workouts have as much as 600mg of caffeine along with other stimulants, but the problem is that using too much caffeine can affect sleep.

If you take your pre workout with 400mg of caffeine early enough, before the afternoon, your sleep should be just fine, although it's pushing the limits.

Caffeine in Research

Caffeine's role as a performance enhancer in sports and fitness has been extensively studied, focusing on the benefits of caffeine, dependent on the dose.

The following studies provide unique insights into this high caffeine dosage's potential benefits and implications on mental and physical performance.

  1. The Effects Of Caffeine On Athletic Performance: This study suggests that caffeine can be a powerful ergogenic aid beneficial in athletic training and performance, stimulating the brain, contributing to clearer thinking, and the ability to concentrate more intensely on the task at hand.

  2. An Assessment of the Consumption of Dietary Supplements by Players of Selected Sports: This study found that around 64% of subjects reported general use of dietary supplements, with caffeine being one of the most popular, and claimed dietary supplementation positively influenced their fitness and efficiency.

  3. Dietary Supplements for Athletic Performance in Women: Beta-Alanine, Caffeine, and Nitrate: This study suggests that caffeine, especially in lower doses, can enhance cognitive functions, which is beneficial for activities requiring mental acuity and focus.

  4. Does Caffeine Enhance Athletic Performance: This study suggests that caffeine might have ergogenic potential in endurance events and can affect VO2 max and exercise performance during incremental exercise.

It's evident that caffeine, especially in lower doses, can enhance cognitive functions, which is beneficial for activities requiring mental acuity and focus.

However, individual responses to caffeine can vary, and its consumption should be tailored to personal tolerance levels and specific performance goals, considering potential side effects such as impaired sleep quality.
