All Pure Peptide products are supplied in lyophilized form to help preserve stability, purity, and product integrity during storage and transportation. This process removes all moisture from the vial, creating a highly stable freeze-dried product that can be stored for long periods of time without losing potency or purity.

Unopened lyophilized vials should be stored in a cool, dry place away from direct light, moisture, and excessive heat. Refrigeration may be used where appropriate to help maintain product quality.

After reconstitution with bacteriostatic water, the solution should be refrigerated at 2–4 °C (36–39 °F). Protect the product from direct light and minimize unnecessary temperature fluctuations to help maintain optimal quality and stability.
