Historically, these anabolic hormones were synthesized from natural plant sterols (plant sterols share many chemical similarities). As anabolic hormones are illegal, require a prescription, and raise the risk of many unwanted side effects, many bodybuilders have long sought natural alternatives. This search led to the invention of the original Natural Sterol Complex more than a decade ago.

Eight distinct and potent components make up the best-selling Natural Sterol Complex formula: plant sterols, amino acids, energy substrates, essential fatty acids (EFAs), electrolytes, performance boosters, nucleosides, and important minerals. These components ensure that Natural Sterol Complex will get you bigger and harder in a shorter period of time.
