Science-first. Purity-obsessed.
Peppy was built by researchers, for researchers. We exist to make high-purity peptides accessible to independent labs without compromising on quality, transparency, or integrity.
Why we exist
Built for independent researchers
Independent research labs deserve the same quality of compounds that large institutions take for granted. We started Peppy because sourcing reliable, well-documented research peptides was harder than it should be. In our competitors, we found inconsistent purity, opaque supply chains, and little to no technical support.
We set out to fix that. Every compound we supply is independently tested, comes with a Certificate of Analysis, and is sourced from GMP-compliant synthesis facilities. We publish the data so you can verify it yourself.
Transparency
We publish Certificates of Analysis for every batch. No black boxes, you see exactly what you're working with before your research begins.
Purity standards
≥99% purity on all compounds, verified by independent third-party laboratories. We hold every batch to the same standard, every time.
Researcher support
Our team understands the science. We provide technical documentation, usage guides, and responsive support for your research questions.
Responsible sourcing
We work exclusively with GMP-compliant synthesis facilities. Our supply chain is transparent, traceable, and held to rigorous quality standards.
Quality assurance
Our quality process
GMP synthesis
All peptides are synthesized in Good Manufacturing Practice-compliant facilities with full documentation of the production process.
Independent testing
Every batch is sent to an accredited third-party laboratory for HPLC purity analysis and mass spectrometry confirmation.
CoA publication
We publish the Certificate of Analysis for each batch so researchers can verify purity and identity before ordering.
Cold-chain dispatch
Compounds are stored and shipped under appropriate conditions to preserve stability and potency throughout transit.
Research use only
All products sold by Peppy are intended strictly for in-vitro scientific research and laboratory use. They are not drugs, medicines, or dietary supplements. They have not been evaluated or approved by the FDA or any other regulatory authority for human or veterinary use. Peppy does not condone, encourage, or support the use of any compound for purposes outside of legitimate scientific research.
