Quality & testing

Tested before it’s listed.

Every lot is assayed by an independent laboratory before it reaches the catalog — purity by reverse-phase HPLC, identity by mass spectrometry, and a unique lot ID linked to its certificate.

• 99%+ — Documented purity
• HPLC + MS — On every certificate
• Endotoxin — Screened every lot

Seven checks on every lot

Reverse-phase HPLC

Purity quantified against reference standards — the headline number on every certificate.

Mass spectrometry

Molecular identity confirmed by mass-to-charge analysis — the compound is what the label claims.

Net peptide content

The actual peptide mass per vial — so your dosing math starts from a real number.

Endotoxin (LAL)

Screened for bacterial endotoxins to a defined threshold on every lot.

Appearance & solubility

Visual inspection of the lyophilate and reconstitution behavior before release.

Heavy metals

Trace elemental contaminants screened against safe limits.

Lot-level archival

Each batch carries a unique lot ID linked to its COA.
