Research Peptides FAQ — Frequently Asked Questions

Yes. Every lot is tested by an independent, accredited laboratory before it's listed, and we publish a certificate of Analysis specific to that batch - never a generic or recycled document. Identity is confirmed by mass spectrometry and purity by RP-HPLC, with our catalog held to a ≥ 99% purity standard.

A COA is the laboratory's report on one specific lot: the compound's identity, its measured purity, the test methods used, and the date of analysis. Because it's tied to a single batch, it tells you about the exact vial you received rather than the product in general.

Every vial carries a code in the format VP-[COMPOUND]-[YEAR]-[BATCH] — for example VP-BPC-2026-014. Enter it in our Batch Verifier, or scan the QR code on the label, to pull up that lot's COA. If a code doesn't return a certificate, contact us before doing anything with the material — every genuine Valhalla lot has a record on file.

Purity is measured by reversed-phase HPLC, which separates and quantifies the target compound against impurities; identity and molecular mass are confirmed by mass spectrometry. Both results, with the method and date, are printed on each lot's COA.

Because documentation is the one thing a researcher can independently verify. We publish analytical data and let it speak for itself rather than making claims about what a compound does. Proof over promises is the entire point of the brand.
