to see gains id use 4ius per day 5 on 2 off for at least 8-12months,split the dosage into twice a day 2ius per shot, the quality from hgh is excellent there are alot of more things to take inconsideration as to what your wanting from it, but if you going to use hgh 4ius per day is the way to go.,
ive done 2ius and can honestly say not much difference at all but when i went up to 4ius wow what quality gains muscle mass fat loss and just felt great,,amazing stuff but what are you hoping for from hgh?
