Testrol (by GAT): Review


Natural testosterone supplements have seen a massive rise in sales in recent years. This is largely thanks to all the bad publicity that the medically prescribed testosterone replacement therapy has been receiving.

With a constant stream of litigation against the manufacturers of these treatments, consumers are looking for alternatives. Natural testosterone supplements seem to be a popular choice for a growing number of men.

Testrol by GAT is precisely one of those products that is designed to fill the void left by the synthetic versions of testosterone offered by TRT.

  • Magnesium (as magnesium oxide) (450 mg) is a type of dietary mineral that is vital for maintaining overall health. Experts believe the moment magnesium levels drop past a certain threshold, a whole host of health complications can arise, including high blood pressure. Studies have revealed that daily magnesium supplementation can increase a person’s tolerance under extreme physical stress, as well as enhancing bone mineral density and muscle oxygenation.
  • Zinc (as zinc sulfate) (30 mg), similar to magnesium is also a type of dietary mineral. Experts believe that zinc usually exits the body through sweat during exercise, and this is precisely why zinc levels can be so depleted after a workout. Zinc plays a number of crucial roles inside the body including reinforcing the immune system, providing antioxidant affects, as well as boosting testosterone production.
  • Selenium (as selenomethionine) (50 mcg) is a type of essential dietary mineral renowned for its antioxidant properties. It also contains a high amount of glutathione enzyme, which has been associated with reducing the risk of prostate cancer.
  • Tribulus Terrestris Extract (500 mg) is a part of Ayurveda, and has long been used to help promote male virility and vitality. In direct contradiction to many claims surrounding this ingredient, tribulus does not actually increase testosterone.
  • Avena sativa (aerial parts) (500 mg) is a traditional herbal remedy that has long been used to help support the mind, the body, and overall mood. Experts believe that this ingredient can increase luteinizing hormone production as well as freeing up bound testosterone.
  • L-Arginine (As L-arginine HCl) (150 mg) is a type of amino acid that is known to enhance blood flow and increase nitric oxide levels. Unfortunately, oral supplementation has not been able to provide improvements in blood flow in humans; this has only been successful in animals.
  • Mucuna Pruriens Seed Extract [10% L-dihydroxyphenylalanine (L-DOPA)] (100 mg) is known to suppress prolactin in males, ultimately meaning more free testosterone to roam around the body. This ingredient has also demonstrated the ability to increase growth hormone production, as well as stamping down on cortisol, which plays a major role in destroying testosterone.
  • Fenugreek Seed (100 mg) is a type of plant that is believed to enhance the immune system, cognition, and overall mood. Surprisingly, a recent study found that it can also increase testosterone, erections rigidity, and power output.
  • Ginkgo Biloba (leaf) (100 mg) is a type of herb normally ingested to enhance brain health. Although it has shown to boost cognition, existing results appear to be unreliable.
  • Eurycoma Longifolia (long jack) Root (100 mg) is believed to be a pro fertility agent as well as a powerful aphrodisiac. Furthermore, this ingredient may be anti-estrogenic and pro-erectile. In terms of testosterone enhancement, there is not enough evidence to suggest just how effective it is in that regard.
  • Epimedium Extract (10% flavonoids as icariin) (whole plant) (100 mg), aka horny goat weed is a powerful aphrodisiac and erectile aid long been used in traditional Chinese medicine. Although it has not thoroughly been tested on humans, preliminary animal testing seems to suggest that it may be effective in enhancing testosterone.
  • Saw Palmetto Berries (100 mg) is a fatty acid mix derived from “serenoa repens”. It is believed it may be responsible for helping to hinder prostate growth, and some experts believe it can increase testosterone but there is no evidence of this.
  • Damiana Leaf (50 mg) is derived from the tunera diffusa plant, a widely recognized aphrodisiac and health tonic. Although there haven’t been many human studies surrounding this ingredient, preliminary rat studies seem to suggest aphrodisiac properties, as well as fatigue alleviation.
  • Cnidium Monnieri (aerial parts) (30 mg) has long been used in traditional Chinese medicine as a pro erectile aid. In terms of testosterone enhancement, there are no qualified studies in existence at the moment.
  • Xanthoparmelia Scabrosa (lichen) (30 mg) is a type of “lichen”, an organism that is made up from a combination of fungus and algae. This ingredient has traditionally been used to treat sexual and erectile dysfunction.

Is the Marketing Honest?

The first advertising claims suggest that Testrol helps to build muscle. This probably rings true because there are a number of proven testosterone enhancing ingredients that will inevitably lead to accelerated muscle growth.

Moving onto the second claim, helps to increase male performance. As a natural result of increased testosterone, overall male performance, be it in the bedroom or in the gym will inevitably increase.

The third claim seems to suggest that Testrol contains nitric oxide boosters. This refers to L-arginine HCL. This ingredient is often touted as helping to improve blood flow and nitric oxide levels. In fact, existing studies seem to suggest that oral supplementation in humans is not effective; therefore, this advertising claim is a bit misleading.

The next claim, supports male hormonal production is basically repeating the first and second claims. An increase in testosterone which is a type of hormone is inevitable with ingredients like zinc and fenugreek.

And the final claim suggests that Testrol is good for maintaining sexual health/testosterone booster. This also rings true because there are a number of testosterone enhancing ingredients as I’ve mentioned in the previous paragraph, and if you pair these with tribulus terrestris, you will bound to notice massive increases in your sex drive.

Final Verdict

Testrol is packed with ingredients, and the way this product is presented is very impressive.

Unfortunately a number of “negatives” really let this product down. Firstly, GAT doesn’t offer a money back guarantee, and this means if you’re not happy with the product or you have an adverse reaction, you will NOT get your money back.

Secondly, I’ve seen plenty of negative feedback from alleged users. People have complained about not noticing any improvements to feelings of sickness.
