Dehydroepiandrosterone sulfate, DHEA sulfate or DHEA-S or DHEAS or androstenolone sulfate, is an endogenous androstane steroid that is produced by the adrenal cortex. It is a metabolite of dehydroepiandrosterone (DHEA), is hormonally inert and may serve as storage for DHEA. Although DHEAS has minimal hormonal activity, it has been thought that it can be converted back into DHEA, which in turn can be transformed into androgens like testosterone and dihydrotestosterone as well as estrogens like estrone and estradiol.
