I don’t know the answer to that for sure. My best guess without looking it up would be that DHT could cause some shut down due to the multiple feedback mechanisms the body usually has in any particular area, but I would expect any suppression to be much less than compared with Testosterone, since much of the DHT is converted on site from Test rather than released via the pituitary axis. The same question could be asked of Estrogen too. We know that DHT will supress Estrogen. Perhaps Westla could chime in for some clarification.
I know that with the amounts and frequency I used, I didn’t notice any shutdown. That said, I also didn’t notice any other effects that people sometimes mention such as increased sex drive, confidence etc.
