How long is HCG good before it goes bad?

[Baron]

I have a 5,000iu ampule in the fridge. im 4 weeks after my last test-c injection right now (short cycle), and i decided i dont need HCG. The nolva im doing seems to be doing more than enough, also i pulled a muscle so i cant really lift. Will the HCG be good for the end of my next cycle in september? Is HCG sensitive like GH? if i shake the vial or drop it by accident does it get destroyed?

Once it's mixed I think it's only good for ~30 days in the fridge.

If its stored correctly, i.e. not in direct sunlight and between 2 - 15 degrees then Im pretty sure it has a 2 year shelf life. It might even be longer than that and im guessing it is! Someone else may be able to refute or confirm this though.
