What is a certificate of analysis?
A certificate of analysis (COA) is a document that reports what a laboratory measured in a specific sample. A useful COA ties the result to one sample and one batch, names the laboratory that did the work, states the methods, and gives results you can compare with the label. A COA is only as trustworthy as your ability to check it, which is why every QLD Analytical certificate has its own test number and QR code linking to a public record on this site.
QLD Analytical is an independent testing intermediary. We don't sell, supply or endorse any product, so we have no reason to prefer a pass over a fail. For more on reading a COA, see our guide what a COA should show.
What our COA covers
Mass spectrometry confirms the sample matches the compound named on the label.
HPLC measures how much of the sample is the target compound.
Shows how much is actually in the vial compared with the label.
Blend quantification, bacterial endotoxin (LAL) and heavy-metals panels are coming soon, on enquiry, while scope is confirmed with our laboratory partner.
Why our COAs can be checked
Published passes and fails. Every certificate we release is listed on the results page, passes and fails alike, unless the customer chose a private or anonymous option at checkout. Results that come back badly are not quietly dropped.
QR verification. Each certificate has a unique test number and a QR code. Scanning it opens the matching record on qldanalytical.com, so anyone holding a vial or a printed COA can confirm the numbers match what we published.
Full laboratory report. The downloadable certificate PDF includes the full laboratory report from Apex Labs Pty Ltd, not just a summary.
Independent. We only arrange testing. We don't sell the products we test.
Sample certificate
See real published records: test QA260926009 (Retatrutide 10 mg) and test QA2609267BD (CJC-1295). Each shows the test number, sample and batch as supplied, dates received and tested, identity, purity and content results, the overall result, a photo of the submitted vial, the laboratory report pages and a PDF download.
How to get a COA
- Order and pay online. Enter the sample name exactly as it appears on the vial on the order page, and pay through Square.
- Get your postage instructions. Once payment is taken, we email you the address to send your sample to and how to pack it.
- Post your sample. Label it with your order reference. We confirm by email when it arrives.
- Offsite analysis. We submit your sample to Apex Labs Pty Ltd.
- COA published. Your certificate is issued with its own test number and QR code, and published unless you asked us to keep it private.
Turnaround
Turnaround is typically 4–10 business days from when we receive your sample, plus postage time. As an example from our published records, test QA260926009 was received on 12 August 2026 and tested on 18 August 2026. Priority testing (+A$100) puts your sample ahead of the standard queue at the lab; it can shorten the wait but does not guarantee a turnaround time.
