MSD Pregnyl ampule storage?

So Ive received my Pregynl and I see that its 2 ampules(1 water and 1 powder) and I'm wondering how I'm going to store the hcg once Ive reconstructed it seeing as the top of the ampule will be broken? I'm assuming these vials are used for once of 5000ui shots..? surely if I reconstruct it and leave the vial open the substance will loose potency ? Solutions guys? Thanks in advance

Store it in a syringe.

Yen I got mine like that too. It sucks. I have asked for a vial not an ampoule next time.

I've only seen Pregnyl in amps, it's the generics that come is vials.

Thanks boss.
Will look into the generic choices. It is so much easier to have a vial rather then store in syringes.

Thanks admin!
