Quality

Testing program

Every production lot is submitted to an independent ISO/IEC 17025-accredited laboratory before release.

• Identity by LC-MS, observed mass against theoretical.
• Purity by RP-HPLC, release specification ≥ 98%.
• Net content per vial by quantitation.
• Endotoxin (LAL) and sterility on selected lots, stated on the report where performed.

Reports are published on the Lab results page with the laboratory’s verification reference. We do not publish supplier-generated certificates.

Lot traceability

Each vial is labeled with product name, catalog number, net content, lot number, and storage conditions. The lot number on the vial matches the published report.

Storage and shipping

Lyophilized peptides are stored at −20 °C, desiccated and protected from light. Orders ship in insulated packaging with cold packs from May through September, and in protective packaging year-round.

Labeling and documentation

Every vial carries the statement “For research use only. Not for human or veterinary use.” A safety data sheet in GHS format is available for each product on request.
