Instead of (3) 5000iu vials of HCG, I ended up receiving (1) 5000iu vial and (1) 10000iu vial. I'm about to start a 12 week test e cycle and plan on taking Human Chorionic Gonadotropin (HCG) @ 250iu 2x per week and blasting it at 1000iu eod for the 10 days following my last injection. Given that the Human Chorionic Gonadotropin (HCG) is only good for a month after mixing, how can I make this stuff last?
