Why is it that some guys who use HCG with TRT have little to no bad effects but some guys have big problems with it? I’m considering TRT but am worried HCG would mess with me maybe, and I don’t want shrunken nuts or loss of fertility.
The answer to your question is biochemical individuality, which doesn’t really answer your question which is how will you respond to HCG. It’s one of those things only you can answer.
There’s is nothing to suggest your balls will shrink into raisins, most only notice 20-30% reduction is testicle size. You can always regain fertility, there are many ways to go about it.
It is partly dependent on how much testosterone, if any, they are already taking and individual differences in test and E2 levels.
