How are your products tested?
Each lot is verified for identity and purity before released from the manufacture. In addition to the manufacture testing for purity, our products also have Certificate of Analysis (COA) from 3rd party testing companies located in the US. Our compounds are tested using High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) for purity. Some third-party COAs come from the manufacturer, listed c/o Optimal Health Labs or Optimal Bio Labs. We further commission independent labs to ensure outstanding quality and among-the-highest purity levels in the industry. NOTE: Optimal Health Lab changed to Optimal Bio Labs effective 12/25/2025.
