What an honest Selank / Semax lab report should show
Use this list on the report a vendor sends you, before you trust the numbers on it. How to read a COA
- Lot match. The lot or batch number on the report matches the one printed on your vial.
- Named, independent lab. The report names a lab you can contact and check it with. A PDF with only the vendor's logo doesn't count.
- HPLC and mass spec. HPLC measures purity and mass spectrometry confirms identity. You need both.
- Recent, batch-dated test. The test is dated for this batch, not one report reused for years.
- Purity isn't identity. A high purity figure says nothing about what the compound is unless the mass spec result matches it.
- Contaminants. Endotoxin, heavy metals and sterility results, where the lab offers them. Most reports leave these out.
