sorry to hear that man, looks like youve got some deciding to do. If it were me id try to get the doc to write you a script for test because that way you'll have your name on it you know? and if your going to be on test the rest of your life you dont want johnny law hassling you about something you need to live on.
have you guys tried HCG? Aromasin? what was your free testosterone, estrogen, and cortisol levels? alot of those things can affect your levels. But the again, you said clomid jumped you up to 600 but after you stopped it dropped back down so i doubt estrogen or cortisol is the problem.
no way would i take 3 -5 years off. i ran a cycle awhile ago and my source got popped so i had no way of getting pct. just tribulus with didnt do shit. i felt like absolute hell for 6 months. imagine that for 3-5 yrs? i would just go hrt if you cant get things going again.
