I have been on transdermal trt for over a year, I still produce a very low amount of test, with the hrt im sittng at 500-600 wich is still low, eventually(soon I hope) I will move to injections and yes its forever. but The point I was stressing to you bud was, I had impaired test production for YEARS but never knew it because I never got blood work, the steroids and ph I took never caused side effects for me so i alwasy figured I was bouncing back to normal, till the lethargy and ed became a real issue, I was forced to go see whats up, thats what was up, it had been a year in a half since my last cycle thats plenty of time, my low score was my new normal- Just be safe homeboy, thats all I am saying. I still got off easy, I never crashed or grew boobs or wanted to die, But i did it wrong and now Im here.
