Selank is independently verified by Ozcanium Analytics at 99.17% purity by UPLC-MS/MS, analysed 28 August 2026. Every batch of Selank is also 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 2 monitored ion channels. The release specification is ≥98.0%. Across the 3 batches published here, measured purity spans 98.92% – 99.73%.

Selank testing — common questions
- Is Selank third-party tested?
- Yes. Selank is independently verified by Ozcanium Analytics, an independent Australian laboratory, at 99.17% purity by UPLC-MS/MS, analysed 28 August 2026 on lot APL-SEL5-2608-01, net content 4.90 mg, verification code OZ-HPLCMS-TS02; bacterial endotoxin below 15.0 EU per vial by kinetic chromogenic LAL, analysed 28 August 2026, verification code OZ-ENDOTX-TPA5. Both reports are published on this page as the laboratory issued them, and each verification code can be redeemed in the lab's own portal so the document is confirmed against their records rather than ours. Every batch of Selank is also analysed in our own laboratory and published here in full.
- What purity is the current batch of Selank?
- Ozcanium Analytics, an independent Australian laboratory, measured Selank at 99.17% by UPLC-MS/MS on 28 August 2026. In our own laboratory, batch APL-SEL10-2608-03, the batch currently shipping, measured 99.45% by HPLC / Mass Spectrometry, tested 19 August 2026. The release specification is ≥98.0%. Across the 3 batches published here, measured purity spans 98.92% – 99.73%.
- How do I find the certificate for the Selank 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. 3 batches are published: APL-SEL10-2608-03, APL-SEL10-2607-02 and APL-SEL10-2606-01. 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 Selank 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 2 monitored ion channels.
