I saw many test DHEA-S.It seems in adults this form is constant and is not converted in to androgenic steroids and has unkwon effects.
“It may be very useful to measure both DHEA and DHEA-S and to assess DHEA/DHEAS ratios”
“Conversion of DHEA to androgenic steroids within peripheral target cells may not necessarily affect circulating androgen levels, but reliably results in a significant increase in the androgen metabolite ADG.”
In other words a DHEA testing could be also linked to levels testosterone and estradiol, but not the DHEAS.
Also they conclude “lead us to predict that although DHEAS may be low, biologically active DHEA will be increased in severe stress”
