Verify that any product or batch has passed independent third-party testing for purity, identity, sterility, and endotoxin. Signed Certificates of Analysis ship with every vial and live here for download by lot number.
Five tests. Every batch. No exceptions.
HPLC Purity
Reverse-phase HPLC quantifies the active compound against impurities. Pass threshold: ≥99%. Most Elixser lots run between 99.5% and 99.9%.
LC-MS Identity
Mass spectrometry confirms the molecular weight of the actual peptide matches the expected sequence. Identity verified at the molecular level, not just by purity percentage
Sterility Screen
Direct inoculation and membrane filtration confirm absence of microbial contamination. Required for any reconstitution research.
LAL Endotoxin
Limulus Amebocyte Lysate test screens for bacterial endotoxin contamination. Pass threshold: below pharmacopeial limits.
