Got some MDMA from the markets. It tested fine (Marquis). Tried some at a festival and it didn't feel like it really hit me in the head though I was gurning a lot.
Is this bunk MDMA? Does that just happen sometimes? situational factors? Baggie full of something else?
Anything related to muscles not really working properly while under the influence of MDMA is usually caused by a lack of magnesium in the body. This goes for the eye wiggles, gurning, etc.
