Correct me if I am wrong on this, but I believe ones age is a big factor when dosing. I am in my early 40's age. So natural testosterone level is less than a man in his thirties . Is this a valid point when deciding dosage?

I understand where you're coming from with this but I don't see that it makes much of a difference. If you're adding 500mg + of test then you're exceeding anyone's natural limit. Its only when you're considering trt that it might make a difference.

The only other concern is running exogenous test too high or too long and disrupting or halting your natural production. Obviously if you're older, then it might not matter any more whether you need trt for ever.
