Unless you are Cody Montgomery, I would advise against it... Growth you have to be on for an extremely long time, and pharm grade growth for a high schooler or freshmen in college, I'll just say there goes your trust fund or scholarship...
You need to learn muscle maturity and some work ethic... Growth hormone does not make u look like a bodybuilder in the magazines... It's a combination of many things...
PS, if you do decide to do it, you need to be on for minimum of 6 months and if you are using Chinese generic gh, just buy more gear cause that stuff is a waste of money... Pharmacy grade growth at a moderate dose should run u about 2 grand alone for an amount needed to grow, and that is without food, bills, rent, gear and other hormones because you have to be on cycle to take advantage of gh... You can't start for 3 months then take a month off... Gotta keep consistency...
