Independent laboratory testing

Every compound independently tested by Ozcanium Analytics

Every compound sold by Australian Peptide Labs, 22 in all, is independently tested by Ozcanium Analytics, an independent Australian laboratory, most recently on 9 September 2026. Open any report below — each carries the lab’s own verification code. Every batch is also analysed in-house by HPLC and mass spectrometry, with a Certificate of Analysis (COA) published for every batch.

Independently tested

Independent laboratory

Ozcanium Analytics tests the compounds listed above for purity (UPLC-MS/MS) and endotoxin (kinetic chromogenic LAL); Bacteriostatic Water and NAD+ are tested for endotoxin only. Reports are refreshed every one to three months, and each carries a verification code you can confirm with the lab.

A Certificate of Analysis for every batch

Before any batch ships we analyse it by HPLC and mass spectrometry against a fixed ≥98.0% specification and publish the certificate in full — not sent on request. Match the batch number printed on your vial to its own certificate on the compound’s testing page.

Why two figures?

The independent laboratory and our own analysis test different lots, so each figure is printed with its own lot number rather than combined into one.

How to read one of our certificates

Every certificate reports the same five tests against the same fixed specification, so any two batches can be compared line for line.

What does the HPLC chromatogram on a certificate show?
The chromatogram separates everything in the vial by hydrophobicity and plots it against time. A single dominant peak is what high purity looks like; every smaller peak is an impurity. The purity figure is that main peak’s area as a percentage of all integrated peak area. Our release specification is the High-Tier Research Grade standard of ≥98.0%.
What does the mass spectrometry result confirm?
LC-MS measures the peptide’s mass-to-charge ratio across several monitored channels. The detected masses should match those calculated from the target sequence — which is what confirms the right compound was synthesised, rather than something merely of similar purity.
What is the specification column on the results table for?
The results table prints the specification beside the measured value for appearance, identity, purity, peptide content and endotoxins. The specification column is fixed house policy, so a batch cannot pass by having its target moved.
How do I match a certificate to the vial I have?
Each certificate reports one production batch and carries that batch’s number, test date and document ID. Match the batch number printed on your vial against the certificate for that batch — not against the compound in general.

For a longer walk-through — what the impurity peaks are, and what the endotoxin figure means for cell work — see our guide to understanding Certificates of Analysis and how HPLC purity is measured. For the difference between our own certificate and an outside laboratory's report — and how to check either one is genuine — see what third-party tested actually means.

What these reports and certificates cover

Independently tested by Ozcanium Analytics: Bacteriostatic Water, BPC-157, BPC + TB-500, CJC-1295 (No DAC), CJC-1295 (No DAC) + Ipamorelin, Epitalon, GHK-Cu, Glow Stack, Ipamorelin, Kisspeptin, KLOW, KPV, MOTS-C, NAD+, Retatrutide, Selank, Semaglutide, Semax, SS-31, TB-500, Tesamorelin, Tirzepatide.

Each of our own certificates is the analysis of a single production batch, run in our laboratory: the HPLC figure is the purity measured for that batch, and the mass spectrometry result confirms the compound's molecular identity. The independent laboratory's reports are published in full alongside them on each compound's testing page.

If a batch you hold isn't listed, email [email protected] with the compound and batch number and we'll send the document.
