Our research-use, qualified-buyer, prohibited-use, documentation, and restricted-product policies.
Last updated: May 2026
PepLab.us supplies analytical-grade biochemical reference standards and laboratory research materials to qualified research customers. Materials are intended exclusively for in-vitro research, analytical method development, identity verification, and laboratory evaluation. Products are not intended for human or animal consumption, therapeutic use, clinical use, diagnostic use, dietary supplementation, dosing, injection, ingestion, or administration of any kind.
All materials are sold exclusively for laboratory research and analytical use. Materials are supplied for in-vitro research, analytical method development, identity verification, and laboratory evaluation only. Materials are not for human or animal consumption and not for ingestion, injection, dosing, administration, therapeutic use, clinical use, or diagnostic use.
Materials are sold only to qualified research customers, including researchers, laboratories, academic institutions, biotech companies, contract research organizations, and other qualified research entities. Before completing a purchase, buyers must acknowledge their qualifications and the research-use restrictions that apply to all materials. Buyers must be at least 18 years of age.
Materials may not be used, resold, or distributed for human or animal consumption, therapeutic use, clinical use, diagnostic use, dietary supplementation, dosing, injection, ingestion, or administration of any kind. Buyers may not represent or market the materials as consumer products, supplements, drugs, or therapies.
Each material is supported by lot-level documentation. Identity is confirmed by mass spectrometry and purity is verified by HPLC through independent third-party laboratories. Certificate of Analysis access is available for review, organized by product and lot number, on our Certificates of Analysis page.
PepLab.us does not list controlled or unsupported product categories or consumer-positioned product framing. We do not present materials with weight-loss, anti-aging, performance, bodybuilding, dosing, injection, or other consumer-outcome claims. Materials are presented solely as analytical reference standards for qualified in-vitro laboratory research, with research-use acknowledgment required before checkout.
