· About Peptex
Built for the laboratory bench.
Peptex produces Certified Reference Materials (CRM) for routine laboratory analysis, research, and scientific education. Every batch is hermetically sealed in sterile glass vials with a nitrogen overlay, accompanied by a Certificate of Analysis and prepared from the highest-quality starting materials with defined purities.
Analysis and synthesis are conducted in peptide-grade clean rooms under tightly controlled environments, with stability tested per lot under distinct light- and heat-stress conditions for every released lot.

Quality & compliance
Six commitments printed on every box.
Coming soon · Verification
Per-vial QR authentication is in development.
We're rolling out a verification system that will let you scan the QR code on a Peptex box to confirm the lot, dose, and certificate of analysis against our catalog. The feature is not yet live — for now, cross-reference the printed batch details with the matching product page.
It's a specialised supply chain that exists to put well-characterised molecules — peptides, hormones, receptor modulators and reference standards — into the hands of laboratories that need them for in-vitro work, method development, and analytical validation. It sits quietly behind academic research, contract research organisations, and quality-control labs across the world.
Format dictates how a compound is stored, dosed, and protected from light, oxygen and moisture. Lyophilized powders in vials offer long shelf life and flexible reconstitution. Ampoules give single-use precision and sterility. Tablets are convenient for oral-route studies. Pens deliver metered doses without separate equipment.
Peptides are short chains of amino acids that sit between small molecules and full proteins. Because they're modular, the field has grown rapidly — they're now central to metabolic research, regenerative studies, and a long list of receptor-targeted investigations.
Selective Androgen Receptor Modulators are reference compounds for in-vitro receptor-binding and selectivity studies. They give research teams a tool to probe how a receptor behaves when only part of its signalling pathway is engaged.
Research is comparative work. The value of any data depends on the reference material being identical from one lot to the next — the same identity, the same purity, the same packaging. A reliable catalog removes one variable from the experiment.
The compound landscape moves quickly. New peptide families enter research catalogs every year, packaging keeps getting more discreet and protective, and traceability standards have tightened across the industry. A good catalog reflects those shifts without adding noise.
