Stowing powder? Good idea?

[musclehealth]

I have made used 10g of powder and have 40g left. Is it a better idea to make the rest of the powder into gear and just let it sit in the vials or should I store the powder and make it when needed? Whats the safest way? Also....how long can finished gear sit in a vial till its no good anymore? Test enanthat to be specific.

Just put your powder in the freezer. You can keep it that way for a few years at least
