dermorphin

A hepta-peptide first isolated from the skin of South American frogs of the genus Phyllomedusa (e.g., P sauvagei), which is a highly potent opioid agonist with selectivity for mu opioid receptors. It is 30–40 times more potent than morphine but less likely to produce drug tolerance and addiction. It has been used illegally in horse racing as it deadens pain, allowing horses to run even if injured.
