GREYGEM.

// COA Library

Verify the standard.

Every product. Every Certificate of Analysis. Independently tested. Published on release.

// The Standard

A fully Canadian
supply chain.

Most peptide testing in this category ships samples to Janoshik in Prague — a respected lab, but one that means weeks of waiting and customs risk for every Canadian seller.

We chose a different path. Every compound GREYGEM sells is sent to Testides Lab in Toronto for independent HPLC purity analysis and mass-spectrometry identity confirmation. Samples never cross a border. Results return in days.

Each certificate carries a unique verification ID. You can punch it into Testides' site and confirm the report is real — not edited, not screenshotted, not ours to fake.

How to read
a Certificate of Analysis.

If you've never read a peptide COA before, here's what each line actually tells you — and what to scrutinize before trusting any vendor.

Every legitimate COA includes

01

Identity by mass spec

The measured molecular mass should match the theoretical mass of the compound, typically within ±0.5 Da . If it doesn't match, the vial contains something different from what's on the label.

02

Purity by HPLC

A single, sharp peak indicates a pure compound. Multiple peaks or significant baseline noise indicate impurities. The percentage is the area of the target peak relative to all peaks — what you actually got.

03

Method stated

The COA should spell out the analytical method and its conditions, so another lab could reproduce the result. A number with no method behind it is a claim, not a measurement.

04

Date of testing

COAs older than twelve months on a still-sold product mean either the testing is stale or the same COA is being recycled. Both warrant questions before purchase.

05

Lab signature

A real COA names the testing lab, lists the analyst or signatory, and provides contact information. If those details are missing or the lab can't be independently verified, the document isn't worth much.

06

Lab verification ID

Testides issues every COA with a unique verification ID. Enter that ID at testides.com you'll see the original report directly from the lab — not a forwarded copy from us. If a vendor can't offer this, ask why.
