4 Androstenedione (Andro): is a pro-hormone that became famous because in 1998 Mark McGuire said he had used it. Andro get converted directly to testosterone at a conversion rate of about 5.6%. Andro has a very high rate of amortization to estrogen and side effects such as gynecomastia (breasts), male pattern baldness, acne and risk of having an enlarged prostate. 4 Androstenediol (4-AD): is another pro-hormone that gets converted to testosterone. Unlike Andro, 4-AD does not get directly converted to estrogen. Also, the conversion rate is almost 3 times higher than with Andro at 15.76%. 1 Androstenediol (1-AD) : unlike the previous 2 pro-hormones, 1-AD gets converted to 1-testosterone, which is a 5- alpha steroid reported to be 700% more anabolic and 200% more androgenic than testosterone. 1-AD has the highest conversion rate and can not be directly or through any metabolic channels be converted to estrogen. Side effects include baldness, testicular shrinkage, enlarged prostate and acn
