My understanding is that clomid works by blocking estrogen at the pituitary. I am secondary that had "normal" LH and FSH levels (a touch above the low end of the normal range) before TRT. However my estrogen levels were extremely low close to undetectable prior to TRT. So if i quite TRT and use clomid only (for the main purpose of maitain fertility) will that work to raise my testosterone levels given i had very low estrogen levels to begin with (so the rationale is given i had very little estrogen and clomid works by blocking estrogen... So there is little to block to make it work). On TRT i have been at 600ng/dl TT and close to 1,000ng/dl TT. I only feel better close to 1,000ng/dl can this level be achieve with clomid only? Or i will better off adding HCG to my protocol? I am 34 years old
