Common Questions

Frequently Asked Questions

Everything you need to know about ordering and using our research peptides

  • How do I verify the purity and COA of my batch?

    Every vial ships with a unique batch number, and you can verify it instantly in our Batch Verification System to download the third-party Certificate of Analysis (COA). All Grey Research Peptides are tested by Freedom Diagnostics using HPLC and mass spectrometry, confirming molecular structure and 99%+ purity. The COA is independent, so you can also confirm it directly on the Freedom Diagnostics website.

  • How should research peptides be stored?

    Lyophilized (powder) peptides should be kept in a cool, dark place away from light and moisture; for long-term stability, store them frozen. Once reconstituted, peptides should be refrigerated and used within their stable window. Our compounds ship in sealed, sterile medical-grade vials specifically to preserve stability during transit and storage.

  • How fast do you ship, and how do you handle temperature control?

    We ship 2–3 day express across all 50 U.S. states. Because peptides are shipped in their stable lyophilized form inside sealed sterile vials, they remain stable at standard shipping temperatures, and every batch is packaged securely to protect it in transit.

  • What payment methods do you accept?

    We accept all major credit cards as well as ACH bank transfers, with a 5% discount on ACH payments. Checkout is secure, and unlike many generic suppliers, we do not restrict you to crypto, Zelle, or Cash App only.

  • What is your refund and satisfaction policy?

    We stand behind every batch with our 99%+ purity guarantee backed by a third-party COA. If a product arrives damaged or does not match its Certificate of Analysis, contact us within [X days] for a replacement or refund.

  • Do you ship internationally or only within the United States?

    At this time we ship exclusively within the United States, including all 50 states. This lets us guarantee 2–3 day express delivery, maintain full chain-of-custody on every batch, and stay compliant with U.S. regulations for research compounds. We currently cannot fulfill international orders.

  • What are research peptides, and what are they used for?

    Research peptides are high-purity, lab-grade compounds intended strictly for in-vitro and laboratory research use only. Grey Research Peptides supplies them in lyophilized form at 99%+ verified purity for professional research applications. They are not intended for human or animal consumption.

  • Are your peptides third-party tested?

    Yes. Every batch is independently tested by Freedom Diagnostics, a U.S. third-party laboratory, using HPLC and mass spectrometry. Results are published as a downloadable COA tied to each batch number.
