Dehydroepiandrosterone (DHEA), DHEA sulfate (DHEA-S), and androstenedione may all be considered proandrogens of testosterone. [1]

AAS like testosterone are used in androgen replacement therapy (ART), a form of hormone replacement therapy (HRT), and for other indications.
It has an affinity (K d) of 0.25 to 0.5 nM for the human AR, which is about 2- to 3-fold higher than that of testosterone (K d = 0.4 to 1.0 nM) [41] and the dissociation rate of androstanolone from the AR is also about 5-fold slower than that of testosterone. [42] The EC 50 of androstanolone for activation of the AR is 0.13 nM, which is about 5 ...
