Beyond the
Molecule.

Research peptides are short chains of amino acids synthesized for use in laboratory and scientific research settings. They are used by researchers to study biological processes, receptor interactions, and cellular mechanisms in controlled in-vitro environments. PeptaPeptides compounds are not intended for human use.

PeptaPeptides compounds are available to qualified researchers, licensed professionals, and research institutions. By purchasing, you confirm that you intend to use the compounds solely for lawful in-vitro scientific research. All products are sold under Research Use Only (RUO) designation.

All lyophilized compounds should be stored at 2–8°C and protected from direct light and moisture. When stored under proper laboratory conditions, the peptides maintain stability for an extended period. Always follow your institution's standard protocols for handling research-grade materials.

Every batch is independently tested by a third-party laboratory using HPLC (high-performance liquid chromatography) to verify identity, purity (≥99%), and concentration. A full Certificate of Analysis (COA) is available for every compound upon request.

Yes. A full Certificate of Analysis (COA) is available for every batch and can be requested at any time by contacting our team. The COA includes HPLC results, mass spectrometry data, and confirmed purity percentages for the specific lot you received.

All PeptaPeptides compounds are held to a minimum of ≥99% purity by HPLC analysis. We do not release any batch that falls below this threshold. Third-party testing ensures no internal bias in our reported results.

Orders over $250 qualify for free shipping. All orders are packed with temperature controls to preserve compound integrity in transit. Orders are typically processed and shipped within 1–2 business days.

All shipments are packed with temperature-controlled packaging to maintain integrity from our facility to your lab. Lyophilized powder form also provides added stability during transit compared to liquid preparations.

Currently we ship within the United States. For international research inquiries, please contact our team directly and we will do our best to assist based on applicable regulations in your region.

We offer a full refund if your compound does not meet 99% purity as verified by HPLC analysis. Simply contact our team with your batch number and we will process your refund promptly. We stand behind every compound we ship.

Our research support team is available 7 days a week. You can reach us through the Contact page on our website or by opening a support ticket. We typically respond within a few hours.
