A research peptide brand built on standards
502BIO is a Korea-based manufacturer of research peptides. We exist to give researchers materials they can trust — verified purity, consistent presentation, a per-lot certificate of analysis, and a unique authentication code on every vial.
Synthesized in Korea, verified before release
Our catalog is produced at established Korean manufacturing partners with documented process control. Korea's peptide-synthesis sector is known for rigorous quality systems, and we hold our line to a 99%+ purity standard verified analytically before a batch ships.
