Is anybody here using HGH that they're one hundred percent sure is real but have zero side effects? I started taking Hygetropin but don't feel anything at all. My friend is using the same batch but feels side effects. I injected 10iu the 1st day and 7iu/day for the last couple of days. I sometimes don't feel anything on the majority of drugs so it won't be a suprise for me if they're genuine. I'm gonna do blood test to confirm.
