Analytical methods
What every batch is tested for
Each lot is submitted to an independent laboratory and analyzed against documented USP method specifications. Results are recorded on a per-lot Certificate of Analysis.
HPLC purity
High-performance liquid chromatography quantifies peptide purity against a ≥98% acceptance specification for each lot.
FTIR identity
Fourier-transform infrared spectroscopy confirms the characteristic bands of the labeled compound for identity verification.
Potency assay
Labeled content is measured by assay and reported on the certificate alongside the recorded mass for the lot.
Transparency
Current batch results
HPLC purity figures below are taken directly from the third-party Certificate of Analysis issued for each current lot. Full certificates — including chromatograms and potency data — are available per product.
Research standards
How material is handled
Lyophilized & sealed
Material is supplied lyophilized in sealed glass vials, prepared and stored to protect compound integrity during handling and transit.
Per-lot documentation
Each lot carries its own Certificate of Analysis with a unique lot number, making every batch independently traceable to its analytical record.
Independent verification
Analysis is performed by a third-party laboratory rather than in-house, so purity and identity figures come from an external source.
Documented dispatch
Orders are prepared in protective packaging with tracking, and shipped to the verified researcher or institution on the account.
