How to Store Research Peptides: Powder, Mixed Vials and Shipping

Most research peptides arrive lyophilized, which means freeze-dried into a powder. In that form they're far sturdier than a liquid.

Before mixing

Keep vials cold, dark and dry. A fridge works for most; a freezer for long-term storage.
Leave the cap sealed until you need the vial.
Let a cold vial reach room temperature before opening, so moisture doesn't condense inside.

After mixing

Keep it refrigerated. Don't freeze it.
Keep it out of light.
Label the vial with the date you mixed it.

In the mail

A few days in transit at normal temperatures is fine for dry powder. Put your vials in the fridge when they arrive.
