MFIII Placenta HP extracts come in concentrated vials containing highly bioactive native placenta extracts. It is the only placenta extract produced using a proprietary cold extraction process without heating, allowing the extracts to retain their molecular structure and bioactivity. Other placenta injectables apply extreme heating during sterilization that destroys most bioactives. MFIII Placenta HP must be stored refrigerated to preserve its activity, unlike extracts produced through heating methods.
