If you are truely on HRT for hypogonadism, you will NEVER "cycle" off. This on and off shit some GP doctors have their patients doing makes absolutely no sense hormonally or physiologically. If I had a diagnosis of hypogonadism (which I do) and my doctor told me to go off what I'm taking, I'd change doctors. All thats asking for is the crash that led for me to be put on those drugs in the first place. Its asanine.
IME, you don't experience the "crash" if you take HCG during cycle and HCG, clomid, nolvadex and(or) Aromasin properly during PCT. The only reason my doctor wants me to come off periodically (6-8 weeks - twice per year) is to lessen the chance that my HPTA will shut down permantely.
I'm a relatively young guy. What if I want to have more kids?
Overall, he's trying to fix the fact that my test levels are in the low 200's, but without making things worse.
