This is my first HGH purchase.I did a lot of reading and listening and came to the decision that the yellows were my best move for the money.Short pharma grade I felt this to be a solid purchase from a reliable source that would provide good results first time.i will start dosing at 2 iu for first couple weeks once daily.Then increase 1 iu every 3 weeks with split dosed till 5 iu daily.
