Glow Labs Certificates of Analysis

Glow Labs certificates of analysis are available on request. This page explains how to ask for one, why the files are not on the site yet, and what a full certificate should show.

How to ask

Send us a WhatsApp message with the compound name, size and, if your vial shows one, the lot number. We reply in the same chat. It is the chat we use for orders too: see how to order.

A certificate is written for one batch, not for a compound in general. The lot number tells us which batch your question is about.

Why on request

We do not publish certificate files on this site yet. When batch certificates issued in the Glow Labs name are ready, this page will list them by compound and lot.

What a certificate shows

A certificate of analysis should name the compound and its batch. It should list each test with its limits and the measured values, and be dated and signed. That is what the ICH Q7 guideline, written for makers of medicine ingredients, asks for. It also says a genuine certificate should be issued for each batch on request.

Section 11.4 of the guideline spells out the parts in more detail:

  • the name of the material, with its grade where that applies
  • the batch number and the date the batch was released
  • an expiry date or a retest date, when the material has one
  • each test that was run, its acceptance limits and the numerical result
  • a date, and a signature from an authorised person in the quality unit
  • the name, address and phone number of the original manufacturer

It should also name the lab that ran the tests and the original maker. This matters most when a certificate is issued again by a repacker, an agent or a broker. In that case ICH Q7 says the new certificate should give the testing lab's name, address and phone number. It should point to the original maker and to the original batch certificate, and a copy of that original should be attached.

ICH Q7 was written for medicine makers. We use it here as a plain checklist of what a complete certificate looks like. It is not a claim that our products are made to that standard. Our guide to peptide purity walks through each part: peptide purity and testing.

Four things to match

A certificate only speaks for the batch printed on it. When you have one in front of you, hold it next to the vial and compare these four things:

  • Compound and size: the certificate and your label give the same name and the same amount.
  • Batch: the batch or lot code is identical on both.
  • Dates: the batch was released before the vial reached you, and any expiry or retest date is still ahead.
  • Lab: a testing lab is named, with an address and phone number you can look up.

If something does not line up, that certificate may describe a different batch from yours. The peptide purity guide has a longer list, including what the test charts should show.

Questions about certificates

What is a peptide COA?

COA is short for certificate of analysis. For a peptide, it is a lab report on one batch. It lists the tests that batch went through, the limit each result had to meet, and what was found.

Does a certificate mean a product is approved?

No. A certificate reports what a lab found when it tested one batch. It is not an approval of any kind. In its April 2026 advisory, the TGA states that unapproved peptide products have not been through its review for safety, quality or effectiveness. Each item in our catalogue is sold for lab research alone: see our research use only notice.
