Prohormones are precursor compounds which are converted through the body into anabolic hormones. When it comes to muscle-building and fat loss effects, prohormones are similar to steroids, and can produce increases in muscle size and strength. And depending on the specific type, also provide the power to reduce excess fat, increase libido, and boost training intensity levels.
Prohormones could be split into three broad categories - the andro group, the 19-nor group, and also the testosterone boosting group. The andro group are converted through the body into natural hormones, including testosterone. The 19-nors are converted by the body into numerous anabolic compounds including nandrolone. Nandrolone is among the main ingredients within the popular anabolic steroid Deca-durabolin (nandrolone deconate). The third number of compounds don't convert to testosterone or nandrolone. Instead they stimulate the body to naturally increase manufacture of a mans hormone for fat loss and muscle building. Typically the most popular product within this category may be the herb tribulus terrestrus.
Since prohormones shot to popularity within the mid 1990's, supplement manufacturers have been waging a "prohormone" war in their attempt to sway bodybuilders towards the merits of their particular "best" prohormone. Like most over-the-counter supplements, the scientific evidence concerning the effectiveness of those products is mixed at best. Some studies claim that these products will in fact increase testosterone or nandrolone levels, and therefore increase muscular size and strength. Other studies show no benefits.
Typically the most popular prohormones currently available include:
1-androstenediol (1-AD)
4-androstenedione
4-androstenediol (4-AD)
5-androstenediol
19-norandrostenedione
19-norandrostenediol
1-androstenediol (1-AD)
Tribulus Terrestrus
Dehydroepiandrosterone, or DHEA
In terms of side effects, the "diols" appear to have less side effects compared to "diones" as they show much less conversion towards the female hormone estrogen. The diols seem to be more potent for weight loss and muscle building as well. Obviously individual genetics often play a significant role in how each compound will respond within an individual's body.
