About PEPTEX Labs

Research-grade peptides, held to a higher standard.

PEPTEX Labs supplies high-purity research peptides to laboratories, universities, and independent researchers across the United States. Every compound we ship is third-party tested, documented with a Certificate of Analysis, and held to strict research-use-only standards — so your work starts with material you can trust.

Our story

PEPTEX Labs was founded on a simple frustration: too many research suppliers cut corners on purity, testing, and transparency. We set out to build a supplier that treats documentation and consistency as the product — not an afterthought.

From sourcing to fulfillment, every batch follows the same disciplined process. We publish Certificates of Analysis, ship cold-chain from the USA, and keep our catalog focused on compounds we can stand behind — giving researchers reliable material and complete paperwork on every order.
