GH honestly is a waste of money for guys younger than 30 or 35, unless your competing. You can spend those $400-$600 on a plethera of test, Deca, Tren, and poor man's IGF-1, insulin. I had contemplated it once, but Im not gonna shell out 1k for a couple kits, for maybe 10-15 lbs of muscle. Plus for it to be effective, you really need to run Anabolic Androgenic Steroids (AAS) and insulin, so add another $500, its just not worth it IMO.
But they are right, 45iu for $400? I hope they send you a case of lube for that ass raping.
