I have been running a variety of hgh for the last year.I change it up for a couple months at a time and see how my results vary.This is the first time using genotrop.A part of me is hoping I don't see any big difference.I ran hyges before this and will follow with generics.After my follow up with naps generics I am gonna write about my differing experiences and blood works and come to a coclusion about what is best for the money.I cant afford this or I obviously would just do it.At this cost its just not worth it to me.I will start at 2iu and go to 5.Shall see.
