I'm wanting to use HCG in my next pct. I've been looking on the internet everywhere to buy it and I finally found a trusted online pharmacy that I think will work, but I'm not sure if it is the right stuff I'm looking for. It says its HCG pregnyl. I"m unsure about the pregnyl part. Does anybody know if this is the right stuff? thanks for your help! It comes in 10000 i.u. and 2500 i.u.
