About Prime Labs

Built for the lab, documented for you.

Prime Labs is a U.S.-based supplier of research-grade peptides, focused on purity you can verify and paperwork you can actually read.

We started Prime Labs with one goal: make research peptides that scientists can trust without guessing. Every compound we ship is produced under disciplined handling, assayed by an accredited third-party lab, and released only once it clears our purity threshold — with the certificate of analysis to prove it.

Purity, on the record

A vial is only as good as its documentation. That's why every production lot is sampled and tested by high-performance liquid chromatography and mass spectrometry before it reaches you. The result is matched to your lot number and filed in our COA Library, available before and after you order.

Made and shipped in the USA

Our fulfillment runs from the United States with fast, tracked, temperature-conscious shipping — same-day dispatch on orders placed before noon EST. When you have a question, you reach a U.S.-based team, not a queue.

Research use only

Everything we sell is intended strictly for laboratory and in-vitro research by qualified professionals. Our products are not for human or animal consumption and are not drugs, supplements, cosmetics, or medical devices.
