Editorial Assessment
American Peptides placed second overall in the most recent cycle. Purity and product accuracy were both strong, and documentation was consistent across the catalogue rather than only on headline products, which is the pattern we look for, because selective documentation usually means selective quality control. It trails the top position on transparency and value rather than on anything measured in a laboratory.
