I have had one experience with this molecule. My dose was about 175 mgs orally, and I weigh about 140 lbs. I first started to notice the effects about 45 minutes after ingestion. At first it was very hard to describe. My mind was slightly stimulated, but a little hazy. I experienced almost no physical stimulant properties, and I am very sensitive to stimulants. The come up lasted about an hour, and then the peak effects began. I felt all of the empathetic qualities of mdma, but much less euphoria. It was more of an extreme mood lift. Mixing it with some good cannabis enhanced the experience greatly. I experienced a nice body high, with shivers occasionally running through my body. Stretching felt amazing, as did masturbation. For the first 3 hours of the experience I felt mentally wired, but physically relaxed. For the next hour after that I began to become very tired, although Im sure that the cannabis contributed to this. After about 4 hours, the experience was over, and I had no trouble sleeping. The next morning I felt a little drained, like after taking mdma, but it quickly wore off by noon. Over all, I think that this is a great substance. Its everything that I expected from methylone, but with none of the nasty side effects. People looking for energy and euphoria as strong as MDMA should look elsewhere, but if you looking for a legal substitute for the empathetic qualities of mdma, it is worth checking out.
