    Does DHEA have a negative feedback loop?

    Just wondering if taking DHEA shuts off your endogenous production of DHEA, or if it just adds to your current DHEA level.

    How long before T, LH and FSH endogenous production shut down after starting testosterone?

    Hi guys just curious: How long will it take until your endogenous production is down to "0" after you start TRT?
