About

About Oxian Labs

Research peptides for qualified laboratories, with the certificate of analysis for every lot published before that lot goes on sale.

Why we publish first

Most peptide suppliers will send you a COA if you ask. We think that is backwards. If the assay data is what justifies the price, it should be visible before you spend anything, not produced afterward on request, and not for a different lot than the one in the box.

So every lot we list has its certificate posted in the COA Library first. You can read the purity figure, the identification method, and the assay date before you decide, and you can match the lot number on your vial against the certificate when it arrives.

What gets tested

Each lot is assayed by an independent US testing laboratory. The current testing panel covers:

Identification: FTIR spectroscopy (USP <197A>), confirming the characteristic bands for the labeled peptide
Purity: reverse-phase HPLC (USP <621>), specification ≥98%
Potency: HPLC assay against labeled content, specification 90 to 110%
Peptide-to-excipient ratio (USP <1151>)
Appearance and mass (USP <630>, USP <41>)

We report exactly what the certificate covers and nothing beyond it. The current panel does not include endotoxin testing, sterility, or microbial contamination screening, and we do not claim otherwise. If your protocol requires endotoxin-tested material, contact us before ordering rather than assuming.

Where we are

Oxian Labs operates from Salt Lake City, Utah. Orders placed before 2:00 pm Mountain Time ship the same business day.

Who we sell to

We sell to researchers, institutions, and companies purchasing laboratory reagents for in-vitro research and analytical work. Verified research accounts get tiered volume pricing, net-30 terms, reserved lot allocation, and a named contact rather than a general support queue. Verification usually takes about two business days.
