QA Decision — Acetate Variance:
Acetate is a counter-ion used in peptide salt form synthesis. Elevated acetate content does not alter peptide
purity (99.39% HPLC), sequence identity (ESI-MS confirmed), or peptide content (85.50%). Aventris QA has
reviewed the full dataset and approved this batch for distribution with full disclosure.
