An androstenediol is any of a group of related steroid androgens.
From my understanding, androstenediol converts to 1-test inside the body. The target hormone for both androstene & androstenediol is 1-test but androstenediol only needs to convert one time in the body to become the target hormone where as androstene needs to go through two conversations. So to answer your question, androstenediol is def the better of the two and I would say androstene is more of a water down hit or miss androstenediol.
Testosterone is produced by the zona reticularis in the adrenal cortex, where a slightly different synthetic route occurs to produce testosterone from cholesterol: cholesterol to pregnenolone, to 17-a-hydroxypregnenolone, to 5-dehydroepiandosterone or DHEA, to androstenediol, to testosterone
Most of these supplements are expensive and vary in effectiveness as to their stated ability to increase muscle mass. The most frequent concern with use of some oral anabolic-like supplements (as androstenediol) is the possibility of liver cancer associated with long-term use. To my knowledge, only creatine supplements with adequate hydration throughout the day have been documented to increase muscle size with few side effects.
No, natural progesterone is not considered an androgen. Naturally-occurring androgens include testosterone, DHT, androstonedione, androstenediol, androsterone, and DHEA. Artificial progesterone (progestin), as found in hormonal contraceptives, has androgenic effects, but only a very mild ones (see related link - See: "There are many types of progestins, and each has a different profile in terms of progestational, estrogenic, and androgenic activity and/or effects.")
