I use it like every few months. Just when I feel like my nuts are shrinking too much and I'll bring them back for a month. No other reason as it does little else for me. Just psychological I think. When your woman is cupping your balls, you want something there. Believe it or not, women evaluate a man more on his nut size than you think.
some people take because they say you got LH receptors thru out the body and its potential to increase preg levels, just speaking for myself and outside of that stuff, my energy levels are better, better sex, even higher libido than just trt alone but almost to the point of being annoying, lol, a little bigger loads, and yes I like a big set hanging, some shrinkage is ok, but my nuts literal ascend at times and I hate that, and hcg prevents it, I only take 250iu twice a week, with that dose I have no issues, some people have e issues with hcg.
