GAT Amino GT Review

Amino GT is a BCAA/Amino Acid supplement by GAT, makers of PMP and Nitraflex, which features a pretty standard array of recovery and performance enhancing ingredients…

GAT Amino GT

BCAAs 2:1:1

Amino GT contains 5g of BCAAs in a 2:1:1 ratio meaning 2.5g Leucine, 1.25g Isoleucine, and 1.25g Valine.  This is the standard ratio when it comes to BCAA supplements, although there is no research indicating any sort of “optimal ratio”.

In fact, given that Leucine is really the only BCAA which produces any sort of meaningful impact on muscle protein synthesis, users of BCAA supplements should really be looking for a high Leucine content above all else.

Leucine supplementation has been shown to preserve muscle in the absence of adequate protein, making it ideal for those who train in fasted state (without eating for several hours prior).

The effective range for Leucine is 3-5g, with Amino GT containing 2.5g per serving.  Ideally, we would have liked to see GAT bump up the Leucine in Amino GT, but it seems the company is sticking to the script with this one and keeping it average.


Glutamine is another standard ingredient commonly including in BCAA supplements, although most of the research tends to be exaggerated.  The reality is that Glutamine may be somewhat useful for combatting exercise-induced immune suppression during high-intesnity, long-duration exercise when immune defenses may be compromised, but it is far from a miracle ingredient.

In the context of Amino GT, it looks like GAT is just sticking to the script.  Glutamine is familiar to most BCAA supplement users, but other than that, there is no real reason to include it…especially at just 1g per serving.


This is probably the single most disappointing aspect of the Amino GT formula.  At this point the research is pretty clear: Arginine just isn’t what it was once thought to be.  Although Arginine plays an integral role in Nitric Oxide synthesis, supplemental Arginine is unreliable and inefficient at best.  Why not use Citrulline instead?  Probably because Arginine is dirt cheap and Citrulline is expensive when used at clinical doses.

Amino GT contains 1g of Arginine.  Even 1g of Citrulline wouldn’t do much, so we’d pretty much just consider Arginine a useless ingredient here.


Although many supplement companies tend to exaggerate the benefits of Taurine, it actually plays a valuable role in the context of Amino GT.

Taurine has been shown, throughout multiple human studies, to reduce exercise-induced oxidative damage, thus favorably influencing recovery.

GAT lists the amount of Taurine in Amino GT at 1g per serving, an effective dose if reducing oxidative stress is the goal.  No complaints there!

Betaine Anhydrous

Betaine appears to be making its way into amino acid supplements so it should come as no surprise that GAT tossed it into the Amino GT formula.

While Betaine is an effective performance enhancing ingredient, Amino GT contains a seriously low dose.  At just 300mg per serving, it’s unlikely that Betaine adds much benefit here.


HICA is a metabolite of Leucine whch has been shown, in one pilot study, to reduce Delayed Onset Muscle Soreness (DOMS) as well as favorably influence body composition.

Unfortunately, Amino GT contains nowhere near the dose used in this study, and with just 100mg per serving, there probably isn’t  enough HICA in the formula to convey any sort of notable benefit.

Green Tea Leaf Extract

Green Tea Extract is generally standardized for EGCG, the compound that is believed to underlie the weight-loss benefits observed in several studies.

However, GAT doesn’t list the amount of EGCG in this particular Green Tea Extract, nor does Amino GT appear to be a weight-loss supplement, so we’re not really sure why Green Tea Extract is included here.

The Bottom Line

Amino GT contains an average dose of BCAAs but just about every other ingredient is under-dosed.  For that reason, we can’t really recommend it to anyone looking for an effective/cost-effective BCAA/Amino Acid supplement.
