I am a 50y.o. male and have run 3 cycles over past 2 years. I have gone from a 6'2" 160 lb. marathoner to a 186 lb. slender dude with a very nice build. I work very hard in the gym year round. My testosterone was tested about 4 years ago, and found to be normal. After each cycle i run 6 weeks Nolva, Clomid, Hcg. I feel Great! Everything seems normal... My question is, am i damaging my bodies ability to maintain normal test levels? When does one decide to have doctor test testosterone levels again, and maybe go on TRT? Can one run cycles while on TRT? Is it really so bad, at my age, to perminantly have to be on TRT? I do not think it would be a big deal, and don't mind lifetime injections..![]()
