What to check on any report
| Check | Why |
|---|---|
| Batch number matches your vial | A generic report proves nothing about your batch |
| Named, independent lab | A lab you can look up |
| Both purity and identity | Mass spectrometry confirms what it is |
| Date and contact details | Undated or anonymous reports are weaker |
