These are laboratory materials, and the specifications are what you are buying. Purity is reported by HPLC as a percentage of total peak area, published at the figure the assay returned rather than rounded into a marketing number. Identity is confirmed by mass spectrometry against the expected molecular weight, and the spectrum is on the certificate. Net peptide content is distinguished from gross vial weight, because trifluoroacetate salt and residual water both add mass. Water content comes from Karl Fischer titration.

Vials are lyophilized powder sealed under vacuum, with fill weight in milligrams and the lot number on the label. Storage conditions and the stability window are printed on every listing. Bacteriostatic water and sterile diluents are stocked separately.

The certificate for each lot comes from a contract laboratory with no ownership connection to this company. Any lot assaying below its stated milligrams is withdrawn from sale, and the certificate stays published on the results page with the rest.

Sold for in-vitro and laboratory research by qualified purchasers only. These compounds are not drugs, not dietary supplements and not approved for human or animal use. We publish no dosing information, no administration protocols and no description of physiological activity, and we will not supply any of that on request.
