Optides

Optides is a US-based research peptide supplier built around verification first. Every batch is independently third-party tested for 99%+ purity, with a Certificate of Analysis included on every order. They ship same-day from the USA, publish lab documentation before purchase, and maintain a research library with compound guides, a reconstitution calculator, and direct support from knowledgeable staff — not a ticketing queue.

Peptidology's editorial top pick and affiliated partner because documentation is batch-specific, easy to locate pre-purchase, and paired with consistent identity confirmation across the catalog.
