The Pepper Labs standard
We work only with manufacturers who release full analytical packages: HPLC purity chromatograms, mass spectrometry identity confirmation, and where relevant, endotoxin and residual solvent screening. Nothing enters the catalogue without a lot number and a matching certificate on file.
Australia wide
Pepper Labs supplies research peptides and laboratory reference materials to researchers, analytical labs and industry professionals across every Australian state and territory. Orders are packed and dispatched domestically, so nothing crosses a border, there are no customs holds and no import charges. Pricing is always in Australian dollars, and shipping is a single flat $15.00 tracked fee per order — no weight bands, no zone surcharges, no handling fees.
Each compound in the catalogue is released only after third-party verification: HPLC purity chromatograms at 99% or better, mass-spectrometry identity confirmation, and where relevant endotoxin and residual solvent screening. Vials arrive sealed as lyophilised powder under inert gas with a lot number that ties back to a certificate of analysis we hold on file and will email on request.
