5a-hydroxy laxogenin was discovered by a American scientist in 1996. It was shown to possess an anabolic/androgenic ratio similar to one of the most efficient anabolic substances, but without the side effects of liver toxicity or testing positive for steroidal therapy. Athletes have found dramatic strength increases in 3-5 days, and muscle mass increases in 3-4 weeks. Muscle mass or fat loss is only a function of caloric intake.
