Verify that any product or batch has passed independent third-party testing for purity, identity, net content, and endotoxin. Signed Certificates of Analysis ship with every vial and live here for download by lot number.
—How we verify
01
Reverse-phase HPLC quantifies the active compound against impurities. Pass threshold: ≥99%. Most Elixser lots run between 99.5% and 99.9%.
02
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
03
The COA reports the measured quantity per vial. For blends, consult the report for individual component amounts. Measured net content is separate from the nominal strength on the label.
04
Limulus Amebocyte Lysate test screens for bacterial endotoxin contamination. Pass threshold: below pharmacopeial limits.
05
Each vial carries a lot number tied to its signed COA. Same lot, same COA, every time. Independently verifiable through the lookup below.
