Under the special Testo-Boost formula, legal and safe alternatives that stimulate the production of testosterone and HGH in the body are meant. These products are mostly based on Tribulus Terrestris, HMB, L-Arginine, DAA, Maca, vitamins, and minerals. These are not "anabolic hormones" but revolutionary products based on natural steroid saponins that promote muscle building. Arginine promotes the production of HGH and the muscle pump effect, helping eliminate lactic acid in the muscles, making it an essential component of pre-workout products. HMB promotes muscle building and muscle recovery. Both substances support muscle growth and aid in muscle recovery.
