I got a bunch of vials of this HGH Frag 176-191 crap (I say crap cuz it's not as good as the hype, but I bought it so might as well get what I can out of it) and never had too much trouble. But for some reason, this one vial I got now is really flaky and I can't even really pull it into a slin pin. Is it OK to shake the crap out of this stuff or is the peptide too fragile for that?
