I started TRT about 5 mos ago. Has improved athletic performance and my life in general. My question: my doc says I will need to stay on test for the rest of my life? What are thoughts on this? Have some of you been on test for years? If so, any sides? So far I've had a slight gyno issue which I am on arimidex for, and that has settled down. I have noticed no other sides thus far. Btw I'm 46 - 5'9 and 172 lbs. 11% bf approx.
