Prohormone & Supplement Ingredients:

4 androstene-3b-ol, 17-one


4-DHEA may appear under the nomenclature 4-androstene-3b-ol, 17-one.

4 androstene 3b-ol, 17-one is a prohormone to 4-androstenediol. And 4-androstenediol is a prohormone to testosterone.

4-DHEA does not have much anabolic activity on its own, but it converts to testosterone in a two-step process involving the enzymes 3bHSD and 17bHSD. 4-DHEA first converts to androstenediol and androstenedione and then to testosterone.

In 2004 several prohormones and steroids in food supplements were forbidden by the American government. Among them were the prohormones of testosterone. However, in the Anabolic Steroids Control Act almost no steroids with a C17 carbonyl group are mentioned. Supplement producers gratefully use this omission, and have marketed 4-androstene-3b-ol-17-one as a testosterone precursor.

Two step pro hormone. stares out as 4-dhea, must be converted to either 4-androstenedione, or 4-androstenediol, and then must convert into testosterone. Alot of chances for it to not make it to test.

It will likely convert rapidly and extensively to androstenedione. Androstenedione can convert somewhat to testosterone but it also aromatizes easily. It may (and this is quite theoretical though based on some fact) convert to testosterone better than androstenedione itself though. And that is because the first conversion can increase NADPH/NADP ratio in liver, and that will help the efficiency of the second conversion.

Eh.... seems to be a lot of conflicting info here. Do your research!
