Recycle is a testosterone booster from Purus Labs. The product description claims the supplement helps the bodybuilder produce more free testosterone to improve workout performance and build muscle faster. The trouble with testosterone boosters is a lack of clinical evidence. Human studies on natural test boosters are rare and the results are often marred by poor controls or the fact that the supplement manufacturer paid for the study. Purus Labs claims all supplements are proven with science, but we did not find any links to research, so how does science support the supplement and where is the proof?

List of Ingredients

Aromatase Inhibition / Estrogen Modulation / DHT Block: Bladderwrack, White Button Mushroom, Resveratrol and Indole-3-Carbinol.

Absorption Amplification / Glucoronidation Prevention / CYP3A4 Inhibition: Quercetin and Piperine.

Product Features

Recycle includes tribulus terrestris. This is the most overused, under performing ingredient sold as a testosterone booster. You can buy this as a standalone supplement or paired with other ingredients. Tribulus is known to increase libido, which many supplement companies market as testosterone boosting. Libido does have a direct connection with testosterone, but there are many natural herbs that boost libido without affecting testosterone levels.

The other portion of the supplement is dedicated to estrogen blockers. This is the real meat of any testosterone booster. If a supplement can block estrogen production, the concentration of testosterone is higher, thus the body reacts more to the testosterone than the estrogen. There is some clinical support for natural estrogen inhibitors, but there are no long-term studies on how the inhibitor affects estrogen production after the supplement is stopped.

Recycle is marketed by a company that has some great marketing tactics, but that doesn’t mean the company offers proven supplements. Some of the ingredients in Recycle are commonly used in testosterone boosters, but this category of bodybuilding supplement is not well accepted, because there is just not enough clinical support. If Purus Labs chose to list come clinical studies supporting the ingredients in Recycle, the bodybuilder would likely give the supplement a shot, but as it stands there is no reason for bodybuilders to choose Recycle or other Purus Labs supplements over the competition.
