E4Euh (Intellex) This recent addition to the psychedelic underground is a long lasting (~14 hours) amphetamine derivative, orally active at about 10-20mg of the free base. Claimed to boost intelligence and encourage verbosity with some MDMA-like effects. Mixes badly with LSD (unlike MDMA). Anyone have any more info on this? Couldn't find anything else anywhere, and it's rare to find something I haven't heard of, LOL. Peace, D.
