What to keep a record of at the point of payment — that is the question, and I have not found it answered plainly anywhere I have looked.
Structured report rather than an opinion, following the format the maintainers asked for.
- Compound: tirzepatide
- Independent testing: Medutest
- Method as reported: reversed-phase HPLC, 280 nm
- Result: 99% area
- Certificate figure for the same lot: 98.7%
I am not drawing a conclusion about the supplier from one lot and I would ask that nobody else does either. I am adding a data point to a record.
