We all should be familiar for the important role estrogen plays at downregulating the HPT axis. And with SERMs or AIs it is possible to increase endogenous test production. But, the body is a very complex machine and has many different feedback loops, with estrogen being only one of them (tho quite significant).
Some claim there is also a little known androgen induced HPTA shutdown. I would like some more info about this if you got it.
Finally, my question is this: If one takes finasteride or dutasteride (or some other 5alpha reductase inhibitor) during a testosterone cycle will this result in a decrease in HPTA shutdown? So if you took an AI and a DHT blocker how much shutdown would still occur?
