What's on the label is what's in the vial.
Every certificate above comes from an independent ISO 17025 accredited lab. No batch ships without one.
Eight assays. Every batch.
The same panel runs on every current certificate. Here is what each test proves.
Peptide Purity
01Reverse-phase HPLC area normalization quantifies the target peptide against every peptide-related peak. Our release standard is 99%+ purity on every batch.
Net Peptide Content
02Measures the actual milligrams of peptide in the vial against the label claim, so 10mg on the label means 10mg in the vial.
Identity
03Retention-time match against a certified reference standard confirms the compound is exactly what the label says.
Appearance
04The lyophilised cake or solution is inspected for color, uniformity, and physical integrity before release.
Fentanyl Screen
05Every batch is screened for fentanyl contamination. Result on every certificate: Not Detected.
Heavy Metals
06Arsenic, cadmium, lead, mercury, and chromium quantified by mass spectrometry against strict screening limits.
Sterility
07PCR-based microbial detection verifies no bacterial or fungal growth in the vial.
Endotoxin
08Bacterial endotoxin quantified in EU/mL by the kinetic method, reported on every certificate.

Questions, answered.
What is a Certificate of Analysis (COA)?
A Certificate of Analysis is a document from an independent ISO 17025 accredited laboratory that verifies the purity, identity, and quality of a peptide. Every current certificate runs the full 8-assay panel: peptide purity (HPLC), net peptide content, identity, appearance, fentanyl screen, heavy metals (ICP-MS), sterility (PCR), and endotoxin.
Where can I find the COA for my product?
Every product page includes a link to view or download the current batch's Certificate of Analysis. You can also request specific COAs by emailing support@peakhaven.com.au with your order number.
How do I read a COA?
Start with Peptide Purity (should be 99%+), then Net Peptide Content (the measured mg against the label claim), Identity (confirmed against a certified reference standard), and the safety panels: fentanyl screen, heavy metals, sterility, and the quantitative endotoxin result. Every row carries its own pass status.
Are the labs you use accredited?
Yes, we partner with ISO 17025 accredited laboratories that specialize in peptide analysis. These independent facilities have no financial interest in our products, ensuring unbiased results.
How often are peptides tested?
Every production batch undergoes full testing before release. We maintain rigorous quality control with no exceptions: if a batch doesn't meet our 99%+ purity standard, it's not sold.
