I just had some blood work done for some other stuff and asked for my free test to be checked. My number came back at 37 on a scale of 2?-142. When I was on cycle in the summer I had some done and it 327, I was on 600mg test 200mg tren e. At what number do you start to look at replacement therapy? My sex drive is nonexistent, I don't recover very well from my heavy training sessions, and I am tired and cranky all the time. Those symptoms and my low number have me wondering if it is time, even though this doc isn't going to do it while still in range. I have no problem self administering, I have a really good supplier, and the gear is nice and clean.
