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.

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.

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.
