I've been on approx 500mg of test since June. I'm on testosterone replacement therapy (TRT) so there's no real reason for me to stop, I just adjust dosages up and down for on and off cycle. Mine have atrophied in density but not really in visible size and it appears all atrophy progression has stopped. I have hCG on hand for what will be an attempt to restart a believed to be dead natural system. It's really cheap and shouldn't have anything to do with gyno aside from the effects it has on testosterone but umm, you'll already be messing with that lol.
