Every batch of Semaglutide is assayed in our own laboratory before it is released. Purity is measured by HPLC / Mass Spectrometry on the PDA 214 nm channel, reported as main-peak area against every integrated impurity peak. Molecular identity is confirmed by LC-MS across 3 monitored ion channels. The release specification is ≥98.0%. Across the 1 batch published here, measured purity was 98.86%.

Semaglutide testing — common questions

Is Semaglutide third-party tested?
Every batch of Semaglutide is analysed in our own laboratory by HPLC / Mass Spectrometry, and all 1 published batch appear on this page with their full analytical results, chromatogram and mass spectrum. Independent third-party verification currently covers a selection of our range rather than every compound, and Semaglutide is not among them at present.
What purity is the current batch of Semaglutide?
Batch APL-SEMA10-2608-01, the batch currently shipping, measured 98.86% by HPLC / Mass Spectrometry, tested 31 August 2026. The release specification is ≥98.0%. Across the 1 batch published here, measured purity was 98.86%.
How do I find the certificate for the Semaglutide vial I have?
Each certificate reports one production batch, so match the batch number printed on your vial against the batch history on this page rather than against the compound in general. 1 batch is published: APL-SEMA10-2608-01. If the batch you hold isn't listed, email [email protected] with the compound and batch number and we'll send the document.
What is Semaglutide tested for?
Every batch is tested for Appearance, Identity (MS), Purity (HPLC), Peptide Content and Endotoxins. Each result is printed beside a fixed specification — ≥98.0% for purity, set as house policy rather than per batch, so a batch cannot pass by having its target moved. Molecular identity is confirmed by LC-MS across 3 monitored ion channels.

Semaglutide identification

The registry identifiers printed on every Semaglutide certificate. They are what lets the compound be checked against a public record independently of anything we assert about it.
