USP Labs’ Test Powder is one of the most popular testosterone booster supplements on the market, due to the marketing of USP Labs. However, are the ingredients proven enough to warrant such hype?
Ingredients and Doses
Thumbs up to USP Labs for letting us see the ingredients and some of the exact doses. Other testosterone booster supplements can hide the amounts of each ingredient, in which case we don’t know if the dosage is high enough to be effective.
Dreaded Proprietary Blend
On the flip side they do include a “proprietary blend” of Trimethylglycine, L-carnitine Tartrate, Aframomum Melegueta Extract and Garcinia Mangostana. For example I know that 230mg of Aframomum Melegueta Extract is effective for boosting T by 300%, based on a conclusive study done on rats. But we do not know the dose of Aframomum Melegueta Extract in USP Labs’ Test Powder, so it could well be less than optimal.
