Blend and other-form rows keep their place and page; they are tagged and left out of the figures above, because a blend certificate reports one purity and one amount for the whole vial.
Seven checks for any THYMALIN certificate
- Batch-matched and independent. The certificate names the lot in your hands and comes from a lab the vendor neither owns nor pays.
- Purity against the range. Read the figure against what other certificates for this compound report. How to read HPLC and mass-spec results
- Mass-spec identity. Only mass spectrometry shows which molecule is in the vial.
- Net content, measured. Purity and quantity are separate questions. Why 10 mg isn't 10 mg
- Endotoxin on the batch. A missing line means not tested, not passed. Endotoxin testing and LAL interpretation
- A lab you can check. Named on the certificate, with a way to verify it. Testing labs we track · Red flags in a certificate of analysis
- What no test shows. A clean certificate says nothing about efficacy, dosing or long-term safety.
