Adapt by name, adapt by nature.
This is the third iteration of Adapt Nutrition’s popular Pre Train, and they say it’s the best version yet.
Now, I cannot fault this company’s dedication to continually improving their product line. They deserve huge praise here, because while several bigger manufacturers have produced below par pre-workouts and left them on sale for years, these guys are always striving to innovate and improve.
With that being said, how does Pre Train X stack up against the other versions? And is it good enough to help Adapt Nutrition finally compete against the big dogs of the fitness industry?
You’ll find out right here, in my official Pre Train X review.

Adapt Nutrition Pre Train X: The Good & The Bad
Adapt Nutrition were correct – this is the best version of Pre Train yet!
This pre workout has been on quite a journey since its first release in 2015. Despite having a great look, the original formula was not very solid at all, and I savaged it with a 1-star review. The guys at Adapt Nutrition were not done, though, updating the formula in 2018 for the slightly better Pre Train v2, which received a 2-star review from me.
Now if you take a lok at the graphic above, you can see that the newly-released Pre Train X has raised the bar.
The highlights here begin with a 350mg dose of caffeine, which is enough to push you towards Jack Black energy levels, and a full clinical dose of l-citrulline, which will provide you with some noticeable improvements to training endurance and recovery speed. Elsewhere in the formula we see some drastic changes from previous versions of Pre Train, with the company opting to include a hefty dose of stimulants (hence “not for tested athletes” on the label!).
This is a real powerhouse of a pre-workout!
Adapt Nutrition Pre Train X – Ingredient Breakdown
Now let’s look at each ingredient in the formula one-by-one.
I’ll show you what each ingredient is supposed to do, whether it can do it, and compare the dose we get here against the dose we’d need for maximum results.
- 350mg Caffeine
Caffeine took center stage in the previous versions, and that remains the case here.
A dose of 350mg is no joke, and will help you to unlock the majority of caffeine’s training-related benefits, which include higher energy levels, better mental focus, increased alertness, and even a slight boost to total calorie expenditure. This will be enough to help you power through even the toughest of workouts, but I woudn’t recommend taking it after 6pm. (1, 2, 3, 4)
- 4.5g l-citrulline
This was the standout ingredient of Pre Train v2, because it gave Adapt Nutrition a unique niche to target with the product.
Unlike the more commonly used citrulline malate, pure l-citrulline has been shown to be more effective for aerobic-based training. It uses the body’s nitric oxide pathways to provide your muscles with a greater delivery of nutrients, prolonging time to exhaustion, leading to more repetitions/bursts being performed (5, 6, 7, 8)
You get a full clinical dose here.
- 3.2g Beta-alanine
Beta-alanine is best-known for the tingling sensation it creates (parasthesia), but it also offers some unique training benefits.
Most notably, it can significantly improve pain tolerance. A 2008 study published in the International Journal of Sports Medicine showed that trainees achieved an average of 22% more reps per set after just four weeks of beta-alanine supplementation. (9)
When I reviewed Pre Train v2 back in 2018 I criticized Adapt Nutrition for increasing the dose from 1.5 grams to 2 grams, questioning why they didn’t just go all in and provide a full clinical dose of 3.2 grams. That’s something they have done here, Pre Train X hits the mark!
- 550mg Stimulant blend
This stimulant blend consists of 300mg Kigelia Africana and 250mg Juniper berry.
The incusion of these exotic stimulants means Pre Train is no longer an automatic green tick for competitive sports, which is something Adapt Nutrition are clearly aware of as they advise that it is “not for tested athletes” in the nutritional panel of Pre Train X.
Kigelia Africana is derived from a plant of the same name, and is otherwise known as the controversial stimulant DMHA. Studies show it has anti-inflammatory, anti-bacterial, pain-relieving properties, which is nice, but the real reason bodybuilders like it is because it creates a very intense, almost euphoric, energy boost during training. This thing will make you feel like Rambo in a field of Vietcong. (10)
Juniper berry, also known as Juniperus communis, first landed on the bodybuilding scene back in 2018, when some countries began cracking down on the use of DMHA. It was originally billed as an eventual successor, but research now shows that it’s not quite as effective (although it does work well alongside both caffeine and Kigelia Africana, so it will kick your butt here!). Nowadays, you’ll typically see this ingredient in “fat burner” products, because it has a diuretic effect which may help trainees to shed unwanted water weight. (11)
Both of these doses are high enough to yield the desired effects.
- 1g l-tyrosine
We have another newcomer to the formula here.
The amino acid l-tyrosine is a precursor to dopamine, which you’ll know as the excitement hormone. It forms a useful tag team with caffeine, the two ingredients combining to increase both energy and endurance. Although a clinical dose of l-tyrosine is 1.5 grams, the one gram included here will be enough to claim most of the benefits it offers with long-term usage. (12)
- 1g Taurine
The inclusion of taurine is the first red blotch on Pre Train X’s report card.
This ingredient can be used to increase mental focus and improve blood flow during exercise, and it’s dirt cheap, so it’s no surprise that it’s very popular with companies who make pre-workouts and/or energy drinks. (13, 14)
However, taurine is the arch nemesis of caffeine, and the two ingredients should NEVER be consumed together. A 2012 study from researchers at Tufts University, Medford, showed that when we consume both ingredients together, taurine actually works against caffeine, preventing it from doing its job, and this clash of the titans can even leave the trainee feeling somewhat sluggish during exercise. It ceases to amaze me why supplement brands continue to make this mistake (it’s not just Adapt Nutrition, you’ll find it in over 80% of pre workouts!). (15)
Adapt Nutrition Pre Train X: Russ’ Rating
There’s a lot to enjoy here.
Adapt Nutrition have created a solid pre workout, and I expect this brand will continue making waves in the supplement industry over the next few years if they persist with this innovative self-improvement approach.
With full clinical doses of beta-alanine and l-citrulline to improve training enduracnce, and generous helpings of caffeine, l-tyrosine, kigelia africana, and juniper berry for a big energy boost, you can expect to perform at close to your maximum ability in the gym. The downside to going down a stimulant-based route is that there’s no betaine anhydrous (an ingredient which was included, albeit under-dosed, in the previous versions of Pre Train). On the flipside, though, they’ve also removed vitamin B3, making this one of the few pre workouts on the market which doesn’t include the ineffective bullshit ingredient niacin.
Overall, not only is Pre Train X superior to both previous versions developed by Adapt Nutrition, it’s actually better than most of the flagship products from significantly larger supplement brands. It receives a very high three-and-a-half stars from me today.
