Ok - sorry to be a pain but I find this very interesting. Would the increased free testosterone levels you exhibit (generally) during TRT not shut you down in exactly the same way as the higher free T induced by non-aromatising steroids? Any secondary effects exhibited by a non-aromatising steroid would also be exhibited by high levels of endogenous testosterone and again cause HPTA shutdown?
In essence I could take a TRT dose of testosterone (or slightly more)and control the negative feedback of estrogen with nolva and ensure that my pituitary continues to secrete FSH/LH?
I am 42 years of age and have on a number of occasions dipped into AS usage. Over the years I used nolva to prevent gyno and never had any issues after cycles, having an easy transition back to every day life, good sex drive etc etc no sign of HPTA issues. Last year I decided to try an AI instead and after a very short, low dose cycle of test prop had enormous issues - it has taken me a year of on/off cycles and PCT's to get back to normal. You are making me wonder wether the use of nolva for all those years was the single factor thjat allowed seamless/side effect free transitions.
