Frequently asked questions

All Clarive Research peptides exceed >99% purity. Identity and purity are confirmed by independent third-party laboratories using high-performance liquid chromatography (HPLC) and mass spectrometry (MS). The results are published as a Certificate of Analysis (COA) for every batch, with the lot number matching the vial you receive.

A COA is the independent laboratory report for a specific batch. It documents the measured purity percentage, the peptide identity confirmed by mass spectrometry, the net peptide content, and the lot number tied to your order. The HPLC trace shows a single dominant peak for a pure compound; the MS result confirms the molecular weight matches the expected sequence.

Lyophilized (freeze-dried) peptides are best kept sealed and protected from light. For long-term storage, −20°C is recommended; they remain stable at ambient temperature during transit. Once reconstituted, store under refrigeration and use within the window appropriate to the specific compound. Always follow your laboratory standard handling procedures.

In-stock compounds dispatch the same day on orders placed before the daily cutoff, with an average delivery time of 48 hours within the continental United States. Lyophilized peptides are stable at ambient temperature for transit; temperature-sensitive items ship with appropriate insulated packaging.

At this time Clarive Research ships within the United States only. We are focused on fast, reliable domestic fulfillment for clinics, laboratories, universities, and research institutions across the country.

No. All products are sold strictly for laboratory and research use only. They are not for human or veterinary use, are not drugs or supplements, and are not intended to diagnose, treat, cure, or prevent any disease. They have not been evaluated by the FDA. By purchasing, you affirm you are a qualified researcher or institution.

Unopened, intact products may be returned within 30 days of delivery. Because these are sensitive research materials, opened or reconstituted vials cannot be accepted for return. If a shipment arrives damaged or incorrect, contact us and we will replace it at no cost.

Yes. We support institutional purchase orders and offer volume pricing for universities, laboratories, and research institutions. Reach out through our contact page with your compounds, quantities, and any documentation requirements, and we will prepare a quote.
