The idea with both HCG and AI from the beginning of the cycle is that the best way to fix a problem is to prevent it from happening in the first place. Anyone you would trust buying legit gear from should know what HCG is and have it available. There are plenty of people that do fine without it, but for me at least, the days of taking whatever on the basis of bro science and hoping it doesn't screw me up too bad are over. Best wishes.
