Ran Klow through our own analytical column on arrival. Came back at 99.1% — above the spec sheet number, which is what you want from a reference supplier.

The peptide monograph for Klow included reconstitution recommendations and lyophilized-state storage half-life — actual numbers, not vague guidance. Saved me an hour of literature search.

Ascénd costs more than the budget vendors. The reason is on every COA, every lot label, and every shipment — and the difference is what makes our reproducibility numbers defensible.
