INDEPENDENT PEPTIDE QC TESTING
Test your China peptides before they ship.
Independent lab testing at the source, so a bad batch gets caught before your order ships. Every sample is tested blind — no seller can shape the result — and you get a standardized, tamper-proof certificate at a permanent link, verifiable by scanning the QR on the vial.

How it works
We're based where the peptides are made, so a vial can reach us before your order ships internationally — and you find out what's really in it while there's still time to act.
STEP 1
Order a test
Pick a package, pay, and get your shipping instructions in minutes.
STEP 2
Send us a sample
One vial to the address we give you in China. We confirm it's arrived with a photo the same day.
STEP 3
Get your verified result
A standardized COA at a permanent link, raw data included. Keep it private or make it public — your call.

Why a pass here actually means something
No seller can shape the result
Every sample is tested blind, under an internal ID. Whoever sells the peptide can't influence — or even see — the process.
We don't sell what we test
We don't sell peptides and never will, so we've no product to protect and no result to favor. Anyone can order a test — buyer or seller — but no one can shape or hide what it says.
A COA can't be faked
Certificates live at permanent URLs on our domain. If a QR doesn't resolve here, it isn't real.
A result can't be recycled
Every code is tied to one sample and one batch, so yesterday's clean COA can't be pinned on today's product.
Nothing is edited after publication
Published results are immutable. A correction is a new version with visible history — never a silent fix.
You see the evidence
Chromatogram, spectrum, and observed-vs-theoretical mass ship with every report — not just a headline number.
What a test does — and doesn't — prove
A COA describes the specific sample we received: its identity, purity, and — depending on the package — net content and impurities. It does not establish that any material is safe, sterile, or effective, that other vials from the same source are equivalent, or that possession, import, or use is lawful in your jurisdiction. Each published COA states in plain English exactly which methods were run and what they can and cannot show.
