if all you want is 4-6 units, why not use peptides?
UG gh is not that reliable, but good peptides work. Real phama gh at 4 units per day has the kit empty in a month. Average price here is aout $1300, not sure about your connections but it's ungodly expensive and almost impossible to get.
Not even sure I'd spend that much unless I was making like 5k/week, clear. Sadly, it's not the case.
