Purity is the HPLC figure as printed. Measured content is the amount of each compound the lab found in the vial. "vs label" is measured content divided by the labelled amount; blends are left blank because the label states a total and the certificate reports each compound separately. Verify any row at pepscan.com.au/verification.
Method and limits
Each row is one certificate for one batch at one strength. VantaLab sends the sample to PepScan Australia without identifying it; the laboratory identifies the compound, measures the amount present and reports purity by high-performance liquid chromatography. We transcribe the printed fields (sample, task number, date, purity, measured content, key) into the site, and this page computes the summary from those fields when it loads. The certificates themselves are in the COA Library.
What this is not: a survey of the Australian market, a comparison with other suppliers, or evidence about what any compound does. It is the test results for our own stock, published so they can be checked. The sample size is 24 batches from a single laboratory over a short window; when a batch is replaced the new certificate replaces the old row, so figures on this page will change over time. The date each certificate was issued is in the table.
Researchers and writers are welcome to cite these figures. Please link to this page rather than copying the table, so readers see the current numbers, and quote the task number and key when referring to a single certificate.
Questions
Who tested these batches?
PepScan Australia, an independent laboratory. Each sample was sent blind: the lab identified the compound itself and measured its purity by HPLC. The task number and unique key printed on every certificate can be entered at pepscan.com.au/verification to confirm the certificate with PepScan directly.
What is the purity range across VantaLab peptides?
Across the 20 single-compound certificates currently published, HPLC purity ranges from 98.92% (BPC-157 10mg) to 99.89% (Epithalon 10mg), with a median of 99.49%. 19 of 20 are at or above 99%. Blends report measured content per compound rather than a single purity figure.
Does the measured content match the label?
For the 20 single-compound batches, measured content ranges from 99.7% to 108.2% of the labelled amount; 18 of 20 measured at or above the label. The exact figure for each batch is in the table.
Is one certificate per product enough?
Each certificate covers one batch of one product at one strength. When a batch is replaced, it is tested again and the new certificate replaces the old one here and on the product page. This page shows the batches currently on sale, not a historical archive.
Can I reuse these numbers?
Yes. Cite this page or the individual certificate (task number and key), and link to vantalab.com.au/test-results so readers can check the current figures. The underlying certificates belong to PepScan Australia and are reproduced with the task and key intact.
Read the certificate, then decide.
Every product page shows the certificate for the batch you would receive.
For research use only. Test results describe what is in the vial. They are not a claim about the effects of any compound, and nothing on this page is advice on use.
