Every lot is independently assayed before it reaches the catalog — purity by reverse-phase HPLC, identity by mass spectrometry, and a lot-specific Certificate of Analysis you can match to the exact vial you receive.
Reverse-phase HPLC
Purity quantified against reference standards — the headline number on every certificate.
Mass spectrometry
Molecular identity confirmed — the compound is exactly what the label claims.
Lot-matched COA
Every batch carries a unique lot ID tied to its certificate. The paperwork matches the vial in your hand.
Independent third-party lab
Assayed by Horizon Analytical, a US-based laboratory. We don't grade our own work.
99%+ documented purity
The standard across the entire catalog — lot after lot, printed on the certificate.
Zero fillers
Pure active compound, lyophilized. No binders, no excipients, no filler content.
Synthesized & lyophilized
Produced to a defined specification and freeze-dried to a room-temperature-stable powder — no cold chain required.
Independently assayed
Samples are sent to Horizon Analytical for HPLC purity and mass-spec identity confirmation.
Certificate published
The COA is archived against the lot ID and posted on the product page for you to check.
Sealed & shipped
Vials are sealed and shipped discreetly within the US, dispatched in about 48 hours.
