Ok medbros help me out.

I suffer from POIS and am going to be prescribed HCG to end it.

Am I gonna be taking this shit all my life? Or do my balls grow permanently and I won't have to worry about this shit after a few shots? Will it shrink my pituitary or fuck with body in any way other than raising testosterone/growing my testes?

This is the study that my treatment is based off of.

Is it safe? What do you guys think? If not, what should I do?
