no reason to dose gh before meals, that only applies to the GH releasing peptides. if you have synthetic, 191aa GH then it can be used whenever you want, granted some methods more effective.
i like it before bed. i don't think i'm the greatest responder to gh or steroids like other people i know who respond amazingly, but 3iu is enough to knock me out if i take it before bed. 4 hours of sleep is enough for me to feel refreshed, it's amazing.
