If you like MDMA for its speedy feeling, methylone or methamphetamine is the drug for you. If you are chasing the empathy, look into 6-APB (aka Benzo fury.) I havent tried it, and i doubt it is BETTER than MDMA, but I heard it is a great empathogen.
There is one combination i reccomend that, in my opinion, is 100x better and more empathetic than MDMA.
Take LSD, let it kick in, wait 3 more hours after it kicks in, and then take an average dose of MDMA. (No more than 125mg).
Im sure you have heard of this practice - candy-flipping -. It is incredible. Highly reccomend.
