An androgen prohormone, or proandrogen, is a prohormone (or prodrug) of an anabolic-androgenic steroid (AAS). They can be prohormones of testosterone or of synthetic AAS, for example, nandrolone (19-nortestosterone). Dehydroepiandrosterone (DHEA), DHEA sulfate (DHEA-S), and androstenedione may all be considered proandrogens of testosterone. [1]

A prohormone is a committed precursor of a hormone consisting of peptide hormones synthesized together that has a minimal hormonal effect by itself because of its expression-suppressing structure, often created by protein folding and binding additional peptide chains to certain ends, that makes hormone receptor binding sites located on its peptide hormone chain segments inaccessible.
This is a list of androgens/anabolic steroids (AAS) or testosterone derivatives. Androgen esters are mostly not included in this list. The major classes of testosterone derivatives include the following (as well as combinations thereof): Testosterone derivatives: direct derivatives of testosterone not falling into the groups below
Androstenedione is a precursor of testosterone and other androgens, as well as of estrogens like estrone, in the body. In addition to functioning as an endogenous prohormone, androstenedione also has weak androgenic activity in its own right. Androstenedione has been found to possess some estrogenic activity, similarly to other DHEA metabolites ...
[1] [2] [3] It is an androgen prohormone of nandrolone and of other 19-norandrostanes. [ 1 ] [ 2 ] [ 3 ] 19-Nor-5-androstenedione, 19-nor-5-androstenediol , and other 19-norandrostane prohormones were considered to be nutritional supplements and were sold over-the-counter in the United States as a result of the Dietary Supplement Health and ...
