What's in the 1%? Peptide Purity Explained is part of the Novusyn Research editorial desk. A 99% pure peptide still contains 1% of something else. What that 1% actually is — deletion sequences, oxidation products, TFA, endotoxin — and why it matters more than the headline number. This prerendered HTML exists so crawlers see route-specific content before the client app hydrates.
