I've been on TRT over 10 years, but I'm tired of it and want to see if my body can recover natural levels. I've been off as long as 5 weeks before without any issues. I've been of for 24 days and today I really noticed in the gym. I had little stamina for my boxing workout and actually felt light headed, couldn't work near as hard on the heavy bag. My strength hasn't changed much when I lifted weights. I'm older now almost 54, so it might be tougher after being on so long. My question is..I was thinking of trying the 90 days of clomid to see if my testicles can regain some size, they've come back a little already, but still way undersized and I imagine I have about a zero test level. My doctor never prescribed hcg, so that's out of the question...Will the 90 day clomid cycle increase testicle size permanenty?? Or do you have to keep doing it and if so for how long? Thank you very much. Sorry so long.
