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.
