Research-grade peptides, held to a single standard.

We founded Nexyra because we kept running into the same problem: research compounds with vague sourcing, missing documentation, and inconsistent purity from batch to batch. Every researcher we spoke to had the same frustration. So we set out to build the supply chain we wished existed — starting with a single non-negotiable: every compound leaves our facility with a third-party HPLC result and a certificate of analysis you can actually verify.

That commitment shapes everything we do. We source exclusively from cGMP-certified manufacturers, maintain cold-chain integrity from synthesis to your door, and publish every batch result we receive. When a result comes back below specification, we don't ship. The economics of doing things that way are harder, but the alternative — guessing — isn't an option when researchers are depending on consistent, documented compounds for their work.

We are a small, UK-based team. Research is the only thing we do. Our catalogue is deliberately curated rather than exhaustive — every compound we carry is one we can supply to our own standard, with documentation attached.
