Testrol Gold ES
- Good serving of Mucuna Pruriens
- Very healthy servings of Zinc and Magnesium
- Good dose of DIM
- Contains A LOT of dead weight
- Tribulus terrestris doesn't do anything
- Shilajit doesn't do anything
- Ginkgo Biloba does not affect testosterone levels
GAT Sport seems like a really reputable brand. We therefore expected Testrol Gold ES to be a hell of a lot better than it is! The formula contains so many ineffective, unproven, over-hyped ingredients. Many of these substances have never been shown to increase testosterone in peer-reviewed clinical trials, which is our guide to deciding what works and what doesn’t. It has actually been conclusively proven that the main ingredient – Tribulus Terrestris – does ABSOLUTELY NOTHING for testosterone levels.
We do get a very healthy serving of zinc, plenty of magnesium, and a good dose of DIM (a fairly good aromatase inhibitor). But that’s it. Nothing in GAT Testrol Gold ES is going to actively increase testosterone levels. Certainly not by an appreciable amount.
Our Testrol Gold ES Review
GAT Sport is a highly respected supplement brand in the sports world. They have a lot of high profile professional athletes representing them, including Jon Jones and Sergio Olivia JR. Their products are extremely popular in the bodybuilding community – lots of guys swear by their supplements, and they use nothing else. They cover all the usual suspects: protein powders, creatine, amino acids, and so on. But it seems that their most poplar product is their testosterone booster, Testrol Gold ES.
What does Testrol Gold ES do?
Let’s take a look and find out!
The bottle says that this product enhances “muscle & male performance”, as well as providing “estrogen support” – reducing it we hope!
The GAT Sport website gives us a lot more detail about what this testosterone booster does, and what that means for users in terms of practical, real-world results:
- Help build lean tissue/body mass
- Enhance training performance
- May help stimulate the body’s own production of free testosterone
An increase in lean muscle tissue and training performance would both result from having higher testosterone levels. Indeed, GAt Sport states explicitly that this is how Testrol Gold ES works.
We get even more detail on the merchant page. We’re told that certain ingredients reduce estrogen levels through the inhibition of aromatase (the enzyme which turns testosterone into estrogen). Other ingredients stimulate the body’s own natural production of testosterone in the testes. Or so we’re told anyway.
On the face of it then, this sounds like a solid supplement.
We just need to figure out how much of this is true, and how much is just GAT Sport pushing their product.
Does GAT Testrol Gold ES really work?
How does it stack up to the best testosterone boosters on the market today?

Testrol Gold ES Ingredients
Let’s take a good look at the Testrol Gold ES formula and see if GAT Sport have been honest in their claims:
Sadly, it looks like GAT Sport have seriously over-promised with this testosterone booster.
That does not look like a very good formula to us – not at all!
Ignoring the vitamin and mineral stack for the time being, the majority of the ingredients in Testrol Gold ES are completely useless in a testosterone booster – they don’t affect T-levels!
Tribulus Terrestris is the main ingredient, and by some margin. We have read several studies which found Tribulus Terrestris totally incapable of influencing testosterone levels, even at large doses. It doesn’t do a damn thing, yet GAT Sport have made it Testrol Gold ES’s main ingredient!
The other ingredients are just as useless – Avena Satvia is just oats (don’t be fooled by the Latin name), and it has no effect on hormone levels whatsoever. The same goes for Eurycoma Longifolia, Saw Palmetto, Shilajit, Arginine, and Ginkgo Biloba (which simply increases blood flow).
Fenugreek does enhance your libido, but it doesn’t do so by raising androgenic hormone levels. It’s a simple aphrodisiac.
DIM and Mucuna Pruriens are great testosterone boosters – one reduces aromatase activity, and the other stimulates testosterone production in the testes. However, these tow ingredients alone can only do so much. They are absolutely swamped by bogus ingredients here.
With so much useless dead weight, we could never recommend this supplement to our readers. We think you would be much better off just buying some Mucuna Pruriens and a good mineral supplement. You’d get the same results and you’d save a lot of money that way too!
Let’s go through the main strengths and weaknesses of GAT Testrol Gold ES in a bit more depth.
- Good dose of Mucuna Pruriens
- Contains an aromatase inhibitor
- Magnesium and Zinc both dosed properly for once!
We’re disappointed with this stack overall, but it definitely has some positive points which we should highlight.
The main selling point in our opinion is the decent Mucuna Pruriens dose.
Each serving of GAT Testrol Gold ES contains 100mg of Mucuna Pruriens, standardized to provide 15% L-DOPA.
Mucuna Pruriens, and L-DOPA in particular, is able to directly stimulate the production of testosterone in the testes. There’s lots of evidence showing that Mucuna Pruriens supplementation leads to significantly higher testosterone levels in men. We see this effect in both young and old, healthy and infertile men (ref).
We understand the mechanism behind this relationship well; it is explained very well by this paper. It’s worth quoting the authors at length:
“It has been reported recently that l-DOPA and its metabolite dopamine stimulate the hypothalamus and forebrain to secrete gonadotropin-releasing hormone (GnRH). This, in turn, upregulates the anterior pituitary gland to secrete follicle stimulating hormone (FSH) and luteinizing hormone (LH) causing increased synthesis of testosterone by Leydig cells of the testis.” (Published 2010 in Evidenced Based Complimentary & Alternative Medicine).
L-DOPA stimulates the release of GnRH, which in turn releases Lunteinizing Hormone, which then stimulates the production of testosterone in the testes.
We think every testosterone booster needs to have a substantial component dedicated to increasing testosterone synthesis in the testes.
It’s also worth noting that Testrol Gold ES prov ides very healthy doses of Zinc and Magnesium.
These minerals are absolutely vital for the proper synthesis of testosterone. They’re so important, in fact, that deficiencies in either mineral will result in a significant drop in testosterone levels.
Sadly, many men today are indeed deficient in both zinc and magnesium.
We normally get these minerals from things like nuts, seeds, cruciferous vegetables, organ meats, and shellfish. We don’t need to tell you that most people – especially in Europe and the US – don’t eat enough of any of these foods.
To make things worse, rectifying a zinc or magnesium deficiency requires you to take much more zinc and magnesium than you would need to just keep your levels nice and healthy in the first place. After all, you need to replenish your stores as well as getting blood levels up!
That’s why we recommend taking a testosterone booster which provides good, healthy servings of both zinc and magnesium. GAT Sport Testrol Gold ES contains 200% of your RDI of Zinc and over 100% of your RDI of Magnesium. These are great doses.
- Tribulus does nothing
- Shilajit does nothing
- Arginine does nothing
- Ginkgo biloba does nothing
- SO MUCH DEAD WEIGHT!
Despite the many benefits listed above, we think the weaknesses of Testrol Gold ES’s formula make this a poor testosterone booster on the whole.
The main issue is the fact that the overwhelming majority of the formula is made up of ingredients that are ineffective, unproven, or extremely weak.
The main culprit here is Tribulus Terrestris (TT).
Tribulus terrestris is everywhere. It’s in pretty much every testosterone booster to have come out in the last 10 years. It is one of the most popular herbal extracts used to try to increase testosterone naturally. Even guys running steroid cycles sometimes use Tribulus Terrestris alongside their gear to get extra juice.
There is absolutely no good reason for this – the only reason TT is widely used is because it is marketed well.
The supplement manufacturers have managed to convince enough bloggers, sports journalists, and amateur bodybuilders that it is effective, so they spread the word.
In reality, Tribulus terrestris has no effect on testosterone levels.
None at all.
We think the scientific evidence is pretty clear on this point – there isn’t much room for interpretation. We therefore think that anybody claiming that TT increases testosterone has either never looked at the scientific literature themselves, or they are simply lying.
To see just how useless TT is, all you have to do is take a look at this trial. Here, researchers took 22 elite-level rugby players undergoing intense pre-season training. They were either given 450mg of TT extract or a placebo once per day. They testosterone levels were measured; the idea was that intense training depletes testosterone in natural athletes, and TT claims to be able to counter this decline.
Here is what the researchers found:
“After 5 weeks of training, strength and fat free mass increased significantly without any between-group differences. No between-group differences were noted in the urinary T/E ratio. It was concluded that T. terrestris did not produce the large gains in strength or lean muscle mass that many manufacturers claim can be experienced within 5-28 days.” (Published 2007 in Journal of Strength & Conditioning Research).
Tribulus terrestris does not increase free serum testosterone levels. So we are really disappointed to see that GAT Sport decided to use it as the main ingredient in Testrol Gold ES.
Tribulus Terrestris is easily the biggest problem with Testrol Gold ES. You can’t afford to use a completely ineffective substance as a main ingredient – not if you want to be competitive in today’s market.
But TT is far from the only example of dead weight in this formula.
There are several ingredients in Testrol Gold ES that do not have any effect whatsoever on hormone profiles. They don’t increase testosterone, they don’t decrease estrogen, and they don’t suppress cortisol.
Shilajit has never been shown to boost free serum testosterone levels by any meaningful amount.
Arginine does not influence testosterone, cortisol or estrogen levels.
Ginkgo Biloba is not commonly used in testosterone boosters, and to our knowledge it has never been studied for its testosterone-boosting properties. Forget about peer-reviewed papers showing that it works, we can’t even find a paper investigating Ginkgo Biloba as a T-booster.
Ginkgo is commonly used in nootropics (brain supplements). It is effective at increasing blood flow by dilating the blood vessels in the brain. This allows for greater brain cell oxygenation and, as a result, better brain cell performance. There is no evidence that it influences hormone levels.
We could go on here, but you get the idea.
The Testrol Gold ES formula is jam-packed with ingredients that DO ABSOLUTELY ZILCH for your free and total serum testosterone availability.
Nothing at all.
In buying this testosterone booster, you are paying good money for a stack that contains a lot of useless plant material. Only a couple of the ingredients in GAT Testrol Gold ES actually help you increase your serum testosterone levels. This is really disappointing from a reputable manufacturer – they should have known better!
Side Effects – Is GAT Testrol Gold ES Safe?
In our opinion, this looks like a fairly safe testosterone booster.
There’s nothing in the GAT Sport Testrol Gold ES formula which makes us particularly concerned about side effects.
It uses pretty commonplace ingredients – these substances are widely used in supplements today (although not all in testosterone boosters), and they have been for some time. They aren’t known to cause any serious side effects as far as we’re aware.
Much more importantly, the ingredients in Testrol Gold ES have all been tested in robust clinical trials using human subjects; they have all been deemed to be generally safe for human consumption.
There’s no nasty surprises in here – no synthetic compounds, no pro-hormones, and no banned substances.
That said, Testrol Gold ES does contain a lot of ingredients. When you’re taking a large number of different herbal extracts at the same time, then your risk of experiencing side effects increases as the likelihood of a negative interaction also increases. This is particularly true when you’re dealing with substances not typically used together (nootropics, strange herbal extracts, and testosterone boosters).
Please monitor yourself carefully and follow the usage instructions provided by GAT Sport. If you experience any side effects whatsoever while using this supplement, discontinue use, seek medical attention immediately, and if possible share your experience with other users in the comments below.
If it very important that you be aware of the following facts while reading these reviews:
- This is not medical advice
- We are not doctors
- This is a general overview of the main side effects for the average user
We don’t know you or your medical history. We therefore can’t possibly give you tailored advice. You might have circumstances very relevant to whether or not this supplement is safe for you. You therefore MUST talk to your regular family physician about your plans to use this testosterone booster before you actually do so.
Always do your own research, and always get medical advice before putting any strange herbal extracts into your body. If doesn’t matter if a supplement looks safe for 99% of people – you aren’t 99% of people!
Testrol Gold ES Review Conclusion – Is It Any Good?
In our opinion, this is not a good testosterone booster. It certainly can’t possibly hope to compete with some of the best supplements on the market right now. It might have been competitive when it was first launched, but some really amazing products have come out in the last 2-3 years. In contrast to these more modern stacks, GAT Sport Testrol Gold ES looks pretty poor.
The main issue with Testrol Gold ES is that the bulk of the formula is simply ineffective for elevating testosterone levels.
Tribulus terrestris is the main ingredient, and we have plenty of evidence to prove that it does not work as advertised.
The same is true for several other ingredients; shilajit, Ginkgo biloba, Arginine, Eurycoma Longifolia – none of these substances increase serum testosterone levels! Until we see hard, scientific proof that they do work, we’re going to go ahead and assume they’re bogus.
There are some good ingredients in here, of course. But they are too weak to really make a big impact.
Mucuna Pruriens is effective, but the extract used here is only 15% L-DOPA. Compare that to the 40% L-DOPA used in Centrapeak!
It’s still a good dose and a good extract strength, but as one of the only active ingredients in GAT Testrol Gold ES, we expect the best and nothing but the best.
Overall, we were pretty damn disappointed with this testosterone booster. If you want to see genuine, meaningful results, then we recommend investing in a more comprehensive testosterone booster – one that packs a bit more of a punch!
GAT Testrol Gold ES is weak and considerably over-priced.
