Premium Peptides. Purity You Can Verify.

All peptides are sourced to a ≥99% purity standard. Each batch is accompanied by a Certificate of Analysis (COA) from third-party laboratory testing that documents the exact purity percentage, lot number, and testing method. You can view the COA for each product directly on its product page before purchasing.

A COA is a third-party lab document that confirms the identity and purity of a specific batch. It shows the compound name, lot number, purity percentage (typically verified by HPLC), and the testing date. When reviewing one, focus on the purity percentage and confirm the lot number matches your product. COA documents for available products are linked directly on each product page.

Bacteriostatic Water (BW) is sterile water that contains 0.9% benzyl alcohol — a preservative that prevents bacterial contamination. It's a standard research supply used when preparing lyophilized (freeze-dried) peptide compounds for use in laboratory settings. Unlike plain water, BW allows a vial to be entered multiple times without contamination risk, making it practical for multi-use research workflows.

We recommend storing lyophilized (freeze-dried) peptides in a standard refrigerator between 36°F and 46°F (2–8°C), in a sealed vial away from light and moisture. Keeping them within this range ensures the compound stays stable and maintains its documented purity for as long as possible. Keep vials sealed until ready for use — each product page also includes compound-specific storage guidance under the Compound Information section.

Most lyophilized peptides remain stable for 24+ months when properly stored at -20°C / -4°F. Once reconstituted (mixed with liquid), stability drops significantly — typically 14 to 30 days at 2–8°C / 36–46°F depending on the compound. Check each product's Compound Information section for specific stability windows.

Orders are prepared within 1 business day. Standard U.S. delivery typically takes 3–5 business days. Lyophilized peptides are stable at room temperature during short transit windows and are shipped in sealed, protective packaging. Cold packs are not required for standard shipments based on documented compound stability — this is consistent with how research suppliers across the industry handle lyophilized material.

Currently, Advanced Aminos ships within the United States only. We are evaluating international shipping for select markets in the future. If you have specific regional needs, reach out through the contact page and we'll note your interest.

Every product comes with batch-level documentation, third-party COA availability, and full lot traceability. We don't make health claims — product pages are built around research context and documentation, not marketing language. You can independently verify purity data through the COA links on each product page. Our ordering process is straightforward and every customer receives a full order record by email.

No. All Advanced Aminos products are strictly for laboratory and in-vitro research use only. They are not intended for human or veterinary consumption, diagnosis, treatment, or prevention of any condition. Placing an order constitutes agreement to research-use-only terms.

Due to the nature of research compounds and handling requirements, all sales are final once an order is fulfilled. If you receive a product that is damaged, incorrectly labeled, or does not match its documented specifications, contact us right away and we will make it right. Please review your order carefully at checkout before submitting.
