Every batch of every product we sell is independently tested by an accredited Australian laboratory. No exceptions. We publish the Certificate of Analysis (CoA) for the active batch on this page so you always know exactly what you’re getting.
Our testing protocol covers identity confirmation, peptide purity by HPLC (high-performance liquid chromatography), mass confirmation by MS (mass spectrometry), and endotoxin levels. We won’t release a batch unless purity is ≥99% and the peptide identity matches spec.
What we test for
- Identity & sequence verification — mass spectrometry confirms the correct peptide.
- Purity — HPLC returns a single quantified peak.
- Endotoxin levels — LAL assay confirms below the limit of detection.
- Appearance & reconstitution — lyophilised cake quality and clarity once dissolved.
Current Certificates of Analysis
Retatrutide 10mg
Tirzepatide-class triple-agonist. Batch tested for sequence, mass, and endotoxin.
How to read a CoA
The most important number on a CoA is HPLC purity — it tells you what percentage of the powder in the vial is the actual peptide. The remainder is typically water content and trace counter-ions, not contaminants. We won’t sell anything that doesn’t clear 99%.
Mass spectrometry confirms the molecule. If you see a peak at the expected molecular weight, the peptide structure is correct. Endotoxin (measured in EU/mg) needs to be very low for any sterile-research application.
