I don't think that I can go a good or focused job without more context.
I did answer your question accurately.
hCG is used to preserve testes and fertility. Most guys testes will shrink on TRT without hCG and some of those also get a dull 24x7 ache. I could write paragraphs re other hCG related issues, but that is why there are the stickies.
I can't easily see what other advice I have provided before and should I duplicate effort, go on an easter egg hunt to see, or not care?
