Everything you need to know about our products, testing, shipping, and policies.
No. All Prestige Peptides products are strictly for laboratory and in-vitro research use only. They are not for human consumption, diagnostic, therapeutic, or veterinary use. Statements regarding these products have not been evaluated by the FDA. Researchers must ensure compliance with all applicable regulations.
Three things: (1) Our six-point full-panel testing protocol that verifies identity, purity, potency, heavy metals, sterility, and endotoxins on every batch. (2) Batch-specific Certificates of Analysis that are downloadable for every product. (3) Independent U.S. third-party laboratory verification — we don’t test our own products; independent labs do.
Third-party testing means our products are analyzed by independent, accredited U.S. laboratories that have no financial interest in the results. This eliminates conflicts of interest and ensures the analytical data is objective and trustworthy. Every batch is tested this way — no exceptions.
Each product page includes a “Download Certificate of Analysis” link. The COA details the batch-specific analytical results, including HPLC chromatograms, mass spectrometry data, purity quantification, and pass/fail results for all six testing dimensions. You can also request a COA for a specific batch by contacting us.
Store lyophilized peptides at -20°C in a dry, dark environment upon receipt. Reconstitute only with appropriate bacteriostatic or sterile research-grade solvent. Once reconstituted, store at 2-8°C and minimize freeze-thaw cycles. Use within the stability window indicated on the product label. Always handle in accordance with your institution’s laboratory safety protocols.
Orders placed before 3PM CST ship same-day. All shipments are discreet and fully trackable. You’ll receive a tracking number via email once your order ships. Standard delivery is 2-5 business days within the United States. Expedited shipping options are available at checkout.
Currently, we only ship within the United States. Researchers outside the U.S. should contact us to discuss potential options, but we cannot guarantee international fulfillment due to varying regulatory requirements for research compounds.
Due to the nature of our products, all sales are final once shipped. However, if a product arrives damaged, compromised, or fails to meet its documented specifications, we offer replacements or full refunds. Contact us within 7 days of receipt with your order number and a description of the issue. See our Refund & Replacement Policy for full details.
