One low result does not characterise a supplier and one high one does not either. The question is whether this lot sits in the left tail of a tight distribution or in the middle of a wide one, and the scorecard's IQR answers it.

Section 2
Annotations
Signed technical comments on records. The index does not moderate annotations for agreement with its own arithmetic, and several of these disagree with it. Where a handle has made the same point on several records, one instance is shown and the rest are reachable from the records themselves.
The index specification is stated on the class page with its source and its reasoning. A record outside it is outside a documented threshold, which is a very different thing from a regulatory status.
The record is published in full, including the impurity table that explains it. A number below specification with a named impurity profile beside it is more useful than a number above specification with nothing beside it.
98.20 % on Melanotan II is below the index specification for the class. The interesting part is the distribution: linear (open-lactam) precursor (+18 Da) at 0.87 % is doing most of the work, and that species is a synthesis artefact rather than a degradation product. This is a process observation about lot KP-2508-J5271, not a storage one.
A tight distribution over three draws is weak evidence of a tight distribution overall. It is still the best evidence available and considerably better than none.
