Saw your post about TRT and testicular atrophy. I have also been on T for 10 plus years. Experienced the same atrophy issues, making Chastity difficult when we started. Began injections of HCG and my testicles have been full and healthy ever since. The only downside of the HCG / TRT combo, if there is a downside, is an increased libido and a definite increase in semen volume.
