This is my first time doing hgh, i have one kexing kit and the rest or jino. I started off with 4iu's a day but im thinking of bumping it up to 5iu's. What do yall think, im doing this strictly for mass, im not to concerned about cutting up. Ill be starting my cycle along with it in aboutr 3 weeks. i wanted to make sure my igf levels were up before i started an aas.
