This pre-workout is being discontinued, get it while you can. Crack is one of the popular pre-workouts and is one of the few good DMAA pre-workouts. Crack packs 120mg DMAA along with nitrates and nitric oxide boosters.
Crack has been the original and best selling pre workout from Dark Labs for years.Â
It's a strong pre-workout with DMAA, caffeine, and nitrates.Â
This original version contains 400mg caffeine along with 120mg DMAA and quite a few nitric oxide boosters to help with pumps.Â
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.Â
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.Â
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.Â
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.Â
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.Â
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.Â
Gorilla Mode comes in two versions: the Original (OG) Version, which includes Kanna and Eria Jarensis, and the V2 Version, which does not. The OG Version offers potent energy with these ingredients, while the V2 Version provides a simpler formula. Gorilla Mode delivers strong energy without risky exotic stimulants like DMAA or DMHA, making it ideal for those seeking powerful energy without gray area stims.
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.
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.Â
Zeus Pre Workout by God Status Labz is known for its potent formula designed to deliver intense energy and euphoria. It’s made for those looking for a strong but euphoric workout experience.
God Status has been providing us the hardcore pre workouts with exotic stimulants for years now.Â
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.Â
This is similar to Dark Energy in that it has 400mg caffeine along with 200mg DMHA, and GABA.Â
The GABA should provide some enhancements to mood, overall it's a great pre workout that does give some nice mood uplift.Â
Going above and beyond, Pre Kaged Elite has one of the biggest servings we've seen in pre workouts.
With over 30g of premium ingredients, this is easily the best pre workout with caffeine.
Pre-Kaged Elite is one of the few pre-workouts that have set even higher standards for dosing citrulline.Â
Elite packs 10,000mg of citrulline, 3.2g beta-alanine, 2.5g betaine anhydrous, and much more.Â
There's also a combination of nootropics combined with caffeine and AmaTea.Â
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.Â
And this is one of the cleanest pre-workouts you can get if you're a drug-tested athlete.Â
It doesn't have any gray area stimulants, nor does it try to go overboard in any area.Â
So if you want something reliable, clean and doesn't have any banned substances, then Pre-Kaged Elite is a pretty good choice.Â
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 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.
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.
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.
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.
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'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.
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.
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.
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.
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.
The list above shows you the best pre workouts with 400mg caffeine.
Some of these pre workouts have more than just caffeine as some of them have DMAA or DMHA.
But if you're looking for something without those kinds of stimulants, then check out Kaged Elite.
