How Long can test cyp be exposed to air?

[Hard.On]

/\ /\ totally agree! There's a reason why they make things that will be going into your body sterile, dont want to risk infection. Why didnt you just buy a vial with the rubber top instead of a twist of cap??

Its too late,
It has already been exposed to too much air,

I know how hard it is to remove those metal vial tops.
His product is now far from sterile.
