Yo guys, I have been on trt for 15 years, continuously. During that time my psa went from 1.6 to 1.0. I still have full head of hair. I am mid 50's and I am in top 1% of my age group in fitness. I am not connected to this site in any way so I shoot from the hip, straight. The single best thing you can do is get your levels up. I have been on same dose for say last 10 years. I have tried creams, both the andro gel and creams made from compound pharmacy. I do the injections, 200mg a week now. You really need to check into this if you are on the fence. If you are an older male, it is the single best thing you can do for yourself. Just my 2 cents, worth.
