What are Prohormones? For starters, prohormones are not hormones that you put into your body, as many people mistakenly believe. These are types of chemical compounds that have been developed to trigger specific effects when they come in contact with androgen receptors. These effects include a significant increase in lean muscle mass, the increased strength and endurance levels, the increased blood supply and even accelerated fat loss. How do Prohormones work? In summary, prohormones are taken orally and turn into active anabolic compounds with the help of natural enzymes when they come into contact with androgen receptors. After this conversion, messages are sent to cell nuclei in the body to stimulate them to trigger the positive effects. Are Prohormones anabolic steroids? People often believe that prohormones are a more natural version of the anabolic androgenic steroids or AAS. In fact, Prohormones are simply fragments of anabolic steroids. Instead of bringing raw testosterone into your body, which is the case with anabolic steroids, you ingest testosterone precursors to force your body to produce this hormone and trigger androgenic effects.
