There is some concern with TRT impacting fertility. Basically, it isn’t a sure enough thing to rely on as birth control. As a little anecdotal evidence, I was watching the documentary Generation Iron with the current Mr Olympia contestants and some of them had young children. And we know they’re on more than 200 mg of test. But if having kids was a major concern of mine, I would be hesitant to commit to TRT unless I really needed it. I just had my first kid and don’t want anymore so it can only help me. You can, like you said, always come off and use hCG to get things going again. Alternatively, you could try hCG mono therapy. I didn’t feel any benefit from it but Chris from Good Looking Loser said he loves the way hCG makes him feel. Everyone’s different.
Yah I like the higher tren then test but I don't know about doing that the first go around with tren. I would try it low and see how you react to it then adjust from there kinda like z says. I would even suggest 75 tren eod. It's potent and I've seen great effects from that dose. You prob won't need the prami at that dose would prob max it at 100 eod if you were good. Then if you were good the whole cycle, next time try higher tren lower test. Like 75 tren ed and 50 test ed. This way you would be doubling your tren compared to the first run but keeping test the same
