one of my suppliers, who is reputable, told me if I ever get gear and feel it may be contaminated or not 100% sterile, that I can inject some grain alcohol (everclear) into the vial, not alot, but enough depending on the size of the vial to make it sterile and kill any germs or bacteria that may be present.
now, will doing this harm the hormone in anyway? will it weaken the compound at all? and last, will it increase the injection pain at all?
