Section 01 — Verification
Every lot, seven checks deep.
We do not grade our own work. Each lot clears seven independent laboratory checks before a Certificate of Analysis is issued against the exact number printed on your vial.
Purity
Reverse-phase HPLC-UV quantification against a certified reference standard. Any lot below 99% is rejected outright.
Identity
Electrospray mass spectrometry confirms the exact molecular mass of the target peptide.
Content Verification
Net peptide content and mass are verified to the labeled claim by amino-acid analysis.
Heavy Metals
ICP-MS screen for Pb, As, Cd, and Hg held below USP <232> elemental-impurity limits.
Sterility
USP <71> compliant sterility screen performed on every fill prior to release.
Endotoxin
LAL kinetic chromogenic assay quantifies bacterial endotoxin on each production lot.
Residual Solvents
GC headspace analysis confirms synthesis solvent residuals are within ICH Q3C limits.
Verified Researchers
Real researchers, real reviews.
