All Amino Club peptides are guaranteed 99%+ pure. Each batch is independently tested by accredited U.S. laboratories using HPLC (High-Performance Liquid Chromatography) and Mass Spectrometry. We provide a Certificate of Analysis (CoA) with every order showing exact purity percentages, molecular weight verification, and amino acid sequence confirmation.

A Certificate of Analysis is an official lab document that verifies your peptide's quality. Key sections include: Purity (should be 99%+), Identity (confirms correct peptide via mass spec), Appearance (should match product description), 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, which inhibits bacterial growth. It is a standard laboratory supply used in research settings. We offer pharmaceutical-grade BAC water in our accessories section.

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

Lyophilized (freeze-dried) peptides are highly stable and can last 2+ years when stored properly at -20°C or 2-8°C. Once in solution, peptides remain stable for 4-6 weeks when refrigerated at 2-8°C with bacteriostatic water, or 7-10 days with sterile water. Always store away from light and avoid repeated temperature fluctuations.

Orders are processed within 0-2 business days. Standard shipping takes 3-5 business days from fulfillment. Every order includes free shipment protection. Lyophilized peptides don't require cold shipping—they're 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 on research materials. Contact our support team for specific country availability. All international orders may be subject to local customs fees and import duties.
