Frequently Asked Questions

What are research peptides?

Short chains of amino acids used in laboratory research. MyPeptides products are sold for research use only — they are not intended for human consumption.

Are all sales final?

Yes. All sales of research-use materials are final. We do not accept returns or issue refunds. If your shipment arrives damaged, contact us with photos and your order number. See our shipping policy for details.

Are the peptides tested?

Yes. Every batch is independently tested by third-party labs at ISO/IEC 17025-accredited facilities for identity and purity. Certificates of analysis are published per batch on our Lab Results page.

Do you ship internationally?

Currently U.S. domestic only. Free shipping on orders $150 and up. See our shipping policy for the full schedule.

What payment methods do you accept?

Major credit and debit cards via our processor. Checkout pending.

How do I verify a batch?

Each product page links to the full lab-result history for that compound. Every COA carries a batch ID, test date, purity percent, assay method, and the independent lab. Scan the QR code on any bottle label to verify.
