Questions, Answered.
Everything researchers need to know about sourcing, purity verification, shipping, and institutional purchasing at Research Peptides.
All Research Peptides compounds are sold strictly as research chemicals for in-vitro laboratory use. They are not drugs, food, cosmetics, or dietary supplements. They are not for human consumption, administration, or therapeutic use of any kind. Purchase implies acknowledgment that the buyer is a qualified researcher using the material in an appropriate laboratory setting.
Every production lot is independently assayed by accredited third-party analytical laboratories using reverse-phase HPLC and mass spectrometry. Each compound is verified to ≥99% purity before release. Results are published on a per-lot basis and tied directly to the vial code printed on each label.
Yes. Every vial ships with a batch-traceable Certificate of Analysis corresponding to its production lot. COAs document identity, purity, mass spectrometry data, and analytical methodology. All current lot COAs are also published in the public COA directory on the site.
We ship within the United States and internationally. Orders are dispatched cold-chain from accredited US research facilities to the verified shipping address on file. International transit times and delivery fees vary by destination, and international customers are responsible for compliance with local import regulations.
All lyophilized compounds are sealed under vacuum in borosilicate glass vials and shipped in temperature-controlled insulated packaging with cold-chain preservation. Typical transit is 2–4 business days. Free shipping is included on research orders of $300 or more.
Research Peptides sells exclusively to qualified research professionals and institutional laboratories — including universities, independent research facilities, and credentialed scientists conducting in-vitro study. All purchases are subject to internal verification and our terms of sale.
Due to the sensitive nature of laboratory reagents, we do not accept returns on opened or reconstituted vials. Damaged, lost, or materially defective shipments are eligible for replacement or refund when reported within 7 days of delivery with supporting documentation.
