Our research peptides ship in stable lyophilized (freeze-dried) form, safe at room temperature during transit. After arrival, keep unopened vials in a cool, dry location away from direct light and moisture. Lyophilized (Powder) Peptides should be stored at -20°C or colder for long-term. Reconstituted (Liquid) Peptides should be stored at 3-8°C.

Peptides ship in lyophilized (freeze-dried) powder form, which remains stable at room temperature and withstands normal transit temperature changes. Studies confirm no meaningful purity loss or degradation occurs during standard shipping durations. Each batch passes initial purity checks, with additional stability validation under typical shipping conditions.

Yes, these peptides are legal to purchase for legitimate laboratory and research purposes when used in full compliance with U.S. federal, state, and local regulations. Our products are clearly labeled "Not for human consumption" and sold strictly as research reagents, not as drugs, supplements, or medical products. Buyers must verify and follow all applicable laws in their jurisdiction, as some compounds may face restrictions in specific areas.

Every batch includes a specific expiration date printed on the vial label and Certificate of Analysis (CoA). Lyophilized peptides, when stored properly in a cool, dry place, generally remain stable for 12–24 months (and often longer when kept at –20°C). Normal room-temperature exposure during brief shipping has no impact. Stability varies by peptide sequence and storage conditions.
