About ProPeptid
Premium peptides, built on trust
ProPeptid was founded to give researchers a dependable source of high-purity peptides — with the testing, documentation, and quality controls that serious work demands.
Our mission
Research is only as good as the materials behind it. ProPeptid exists to remove uncertainty from the equation by delivering peptides of consistent, verified quality — every vial, every batch.
We manufacture in the United States and put every lot through third-party analytical testing. Each product is sealed in a glass vial as a lyophilized powder and paired with a certificate of analysis so you know exactly what you are working with.
From synthesis to cold-chain shipping, our process is designed around one priority: giving researchers material they can trust.
Purity first
We hold every product to a ≥99% purity standard, verified through analytical testing before it ever ships.
Transparency
Batch-specific certificates of analysis mean you always know the identity and purity of what you receive.
Made in the USA
Our peptides are produced domestically under strict quality controls, never sourced from anonymous suppliers.
Built for research
Consistent, reliable material so researchers can focus on their work with confidence in their inputs.
