HCG - How important is it?

[bogdan84uzy]

Lasdt cycle I actually used sterile water from the needle exchange here in the UK. It was kept for about 15-20 days in the fridge and it worked fine.

How do I know that? Because HCG gives me a little acne, my testes size returned and my PCT was pretty easy once the SERMs kicked in.

thank you very much for the answer!appreciate it!
