My current protocol is 100mg testosterone cyp every five days with .25 Arimadex every four days which keeps me stable at desired BW range. I plan to pin 250 or 500 iu HCG every other day. Assuming this will kick start my nearly entirely atrophied testicles and raise my natural levels, should I alter my testosterone injections? Arimadex remains the same? I am 64 years old.
