Buy Metonitazene (etonitazene) Cas 14680-51-4

Metonitazene is an analgesic compound related to etonitazene,^[2][3] which was first reported in 1957,^[4] and has been shown to have approximately 100 times the potency of morphine by central routes of administration,^[5][6] but if used orally it has been shown to have approximately 10 times the potency of morphine.^[7]

Its effects are similar to other opioids such as fentanyl and heroin, including analgesia, euphoria, and sleepiness.^[7][8] Adverse effects include vomiting, and respiratory depression that can potentially be fatal.^[9] Because of high dependency potential and dangerous adverse effects it has never been introduced into pharmacotherapy. It is instead commonly used in the illicit manufacture of counterfeit oxycodone opioid pills.^[10]

In the United States, metonitazene is a Schedule I controlled substance under the Controlled Substances Act.
