When it was widely available, I combined butylone with methylone and found it similar to an MDMA experience. Individually, I didn't get much from either one and when I combined them I took a large amount, so I don't know if that was a good idea anyway. When I say they didn't do much for me I mean that they were one-dimensional and everything was surface, without introspection. When combined I did get introspection and music appreciation. I did feel like I was rolling but differently from MD(M)A. I don't know if I should recommend it but I enjoyed it and repeated the experience several times
