I still have a about 3mls left in one of my test prop vials...its pharm grade and i just noticed now after my shot that theres a hair like thing floating in it...its so small and its not a hair just looks like it. the gear was clean, im thinking maybe a piece of the rubberstopper could have came off, from every day pinning?
is it now not good to use and am i good since i just did a shot using the same gear?
thanks...
