Every lot is assayed on its own.

Fragment peptides are easy to mislabel, the difference between the correct sequence and a truncated one is invisible without analysis. Every lot ships with an independent HPLC and mass-spec assay.

Ordering questions

Can I see the COA before ordering?

Yes. The assay record for the current lot is published on this page: lot number, purity, content, methods, laboratory and test date. The How We Test page explains what each figure means.

How is each batch tested?

Every production lot is assayed at an independent laboratory: reverse-phase HPLC for purity and mass spectrometry for identity. The result is recorded against the lot number printed on the vial, so the vial in your hand traces to a specific assay.

Do you ship internationally, and is there local delivery?

We ship worldwide with tracked delivery from regional hubs. In several cities this product is also held in local stock with same-day delivery; the delivery section above shows which.

What is the legal and research-use status?

Everything in the catalogue is supplied strictly as a research chemical for laboratory use by qualified researchers. Nothing is sold for human or veterinary use, and every order is placed under the research-use terms.

What supplies do I need alongside it?

Lyophilised peptides are reconstituted with bacteriostatic water, stocked in the same catalogue along with sterile supplies. The dilution calculator on this site does the concentration arithmetic for you.
