How long is a 10ml vial of test cyp good for?

[blondes]

Wondering once you draw from a 10ml vial of test cyp how long will the vial stay good for? Is there a certain amount of time you should use the vial within?

Once you penetrate the rubber stopper,depending on pin size there's a small chance that air can get into it,if it did close back up it should be good for a few years,altho some potency may be lost! I had some I used and went back to finish it 2 yrs later and it was still good. so i hope that answers your question.
