The purity and accountability we require in every sourcing center we use. The repeatability of the research results is imperative to any and all research around peptides. Standing behind the product is another priority as every order, every SKU has a certificate of purity from a 3rd Party Lab. We verify on every lot:
- Identity & chromatographic purity — HPLC-UV/VIS
- Net peptide content (assay) against label claim — HPLC-UV/VIS
- Sterility — confirmed by two independent labs: USP <71> plus rapid ScanRDI detection
- Bacterial endotoxins — LAL (USP <85>)
- Elemental impurities — ICP-MS for arsenic, cadmium, chromium, lead, and mercury
- Residual solvents — GC-MS across the full solvent panel
- Container-closure integrity — dye ingress
- Solubility confirmation — reconstitution in water
- Residual trifluoroacetic acid (TFA) — ion chromatography
For in-vitro research use only (RUO). Not for human or veterinary use.
Setting the Standard in Analytical Testing Compounds
Our guarantee that is different from other facilities:
- Up to 23 vials sampled per batch, so results represent the batch — not a single token vial
- Sterility confirmed by two independent labs and two methods (USP <71> + rapid ScanRDI)
- Bacterial endotoxins screened on every lot (USP <85>)
- Elemental impurities (heavy metals) screened by ICP-MS — arsenic, cadmium, chromium, lead, mercury
- Residual solvents, container-closure integrity, and solubility verified on every lot
- Residual TFA measured by ion chromatography — a manufacturing by-product most suppliers never check
- Tested only at U.S.-based, ISO/IEC 17025-accredited third-party laboratories
- Produced in facilities with cGMP-aligned quality systems
- Same-day shipping on orders placed by 2:30 PM EST (business days)
- Discount for verified current & former U.S. military, law enforcement, and government employees
