Retain lyophilized vials at -20°C in a frost-free freezer, shielded from light and humidity. Stability spans 3–5 years under proper conditions.
Our Commitment to Quality and Fairness
Peptides undergo third-party confirmation of ≥99.9% purity, accurate mass, and lyophilized state before dispatch. Given their sensitivity for lab-only use, returns are restricted once orders leave our control to maintain supply integrity for all investigators. We review valid concerns individually and support our products accordingly.
