Lyophilized peptide powders may shift or compact during shipping, which can cause clumping or changes in appearance. This is normal and does not affect product quality or purity.

Proper storage is essential to maintain compound integrity.

  • Lyophilized (dry) peptides:
    May be stored at controlled room temperature for short durations when kept dry and protected from light. Short-term storage of up to approximately 2–3 weeks is generally acceptable under these conditions.

  • Reconstituted peptides:
    Should be stored under refrigerated conditions, typically 35–40°F (2–4°C). Reconstituted materials should be handled carefully and used according to laboratory best practices to minimize degradation.
