About Pegasi

Pegasi Peptides was founded on a simple conviction: researchers deserve better. Better purity. Better documentation. Better service. In a market flooded with inconsistent sourcing and opaque supply chains, we built Pegasi to be the standard others measure against.

Pegasi Peptides maintains research-use product documentation and makes batch Certificate of Analysis documentation available on request. Our catalog is organized around clear compound data and a research-only product standard.

Pegasi is founder-led by design. We work directly with synthesis and fulfillment partners, review supplier and batch documentation, and use Uptime for third-party order fulfillment. Our focus is a documented, research-only product experience.
