Do yellow UFC pills trip you out hard?

An ecstasy pill with a high MDMA rating, believed to also have small traces of Ketamine. The amount of Ketamine, however, is so low that it can not be felt. This pill is found in Southern California. Two different designs have been distributed under the same name, however, both are strong and neither is considered a bunk pill replicating another. One has the letters "UFC" actually spelled out and another has a fist punching forward.
