A CoA is an official lab document verifying peptide quality. Key sections include purity (should be 99%+), identity (mass spec confirmation), appearance, and endotoxin levels (should be below 1 EU/mg). Each CoA is batch-specific and available on product pages.

Bacteriostatic water (BAC water) is sterile water containing 0.9% benzyl alcohol to inhibit bacterial growth. It is a standard laboratory supply, and we offer pharmaceutical-grade BAC water in our accessories section.

Lyophilized (freeze-dried) peptides are very stable. For short-term (under 3 months), store at room temperature in a cool, dark place. For long-term, refrigerate at 2-8°C or freeze at -20°C, avoiding repeated freeze-thaw cycles. Properly stored, they can remain stable for over 2 years.

Lyophilized peptides last 2+ years when stored at -20°C or 2-8°C. Once reconstituted with bacteriostatic water and refrigerated (2-8°C), they remain stable for 4-6 weeks; with sterile water, 7-10 days. Keep away from light and temperature fluctuations.

Orders are processed within 0-2 business days, with standard shipping taking 3-5 business days. Free shipment protection is included. Lyophilized peptides do not require cold shipping (stable at room temperature). All orders ship in discreet, unlabeled packaging

Currently, we ship to all 50 U.S. states. International shipping varies by country due to customs regulations. Contact support for specific country availability. International orders may be subject to local customs fees and duties.
