Research peptides, documented
Know your molecule. Down to the lot.
Vellum treats every lot like a published result — third-party analyzed, lot-linked, and verifiable by anyone, before purchase.
For laboratory research use only. Not for human or veterinary use, and not a drug, food, or cosmetic.
What we stand on
Provenance, not promises
Every vial traces to a specific lot, a specific lab, and a specific test date. We link the document — you don't take our word for it.
The analysis is the product
HPLC and mass-spec data, purity, endotoxin and heavy-metal panels — published per lot, downloadable as a signed PDF, scannable from the vial.
Compliance as a feature
Research-Use-Only is stated plainly and everywhere. Clear, honest, and processor-grade — not buried in fine print.
Premium means legible
Quiet typography, real photography, room to breathe. We look like the science, not like the marketplace.
The Vellum Standard™
A public, fixed protocol every catalog lot must satisfy before it can be listed. “Meets the Vellum Standard” is what premium means here — lot by lot.
- Independent assay — Every lot is tested by a third-party, US-based accredited lab — named on the certificate.
- Dual method — Purity by HPLC and identity by mass spectrometry. Two methods, not one.
- Full panel — Endotoxin, heavy-metal, and fill-weight results are reported — not just a purity percentage.
- Lot-linked & signed — A tamper-evident, signed certificate of analysis bound to the exact lot number.
- Open verification — Anyone can confirm a lot at /verify — no account required.
