How long does an open already pierced vial last?

My source is a great guy and was running a special so I decided to stock up for 2 cycles. I was wondering long does a vial remain "good" under proper storage and conditions. Lets say I have half a vial left and plan to save the remaining for the next cycle...would it be ok months away? Thanks ahead for the responses and stay safe.

yes. it would be fine. assuming you are always clean and you practice safe storage.. it'll be good a yr later. idk what the longest people have gone but i'd bet there are some who have gone much longer.

I’ve never really put a time limit in it. I store everything in a cool dark place and would expect it to be ok for years really,

The only thing that could happen is some crystalization forming, but warming the vial will take care of that.

Thanks for the responses. I wonder how long has anybody kept and used an open already used vial of gear.
