    Summary TheDrug.Wiki

    Very little pharmacological or toxicological data exists. Based on structural similarity to mCPP and TFMPP, this compound likely acts as a non-selective serotonin receptor agonist and serotonin releaser. These phenylpiperazines are notorious for producing nausea, migraines, anxiety, and dysphoria rather than euphoria.
