Sourcing › Vendor reports third-party testing batch & lot numbers certificate of analysis documentation quality

i.almeidaTL2 Moderator8 Apr 2026#1

Why our vendor pages link the storefront and mark it sponsored I have a specific reason for asking rather than idle curiosity, and the context is below.

Structured report rather than an opinion, following the format the maintainers asked for.

Compound: semaglutide
Independent testing: Janoshik
Method as reported: reversed-phase HPLC, 220 nm
Result: 99% area
Certificate figure for the same lot: 98.2%

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.

the opening post answers the question as asked. The question underneath it is different.

For anyone arriving from a search: the marked solution above is the direct answer, and the replies underneath it add the caveats that make it safe to use.

Structured report format: compound, lot, independent testing service, method as reported, result, and the certificate figure for the same lot. One lot is one lot. It becomes a pattern at three or four, and it becomes a disputed record when asked and not explained.
