SWIM recieved 500mg of methylone from a source of good reputation, and decided to get his feet wet yesterday. The substance was sold as 2-methylamino-1-(3,4-methylenedioxyphenyl)propan-1-one, and was a brownish coloured powder. To begin with, 100mg was weighed out, and put into a capsule. This was done three times total, making 3 100mg capsules. The rest was put into a small zip, for use later. +0:00 SWIM began by breaking out 20mg of the powder, and insuffulating. No real burning sensation (I have snuffed DMT, so his nose loves things that don't hurt...), but the drip was horrible. +0:01 The capsule was swallowed, and SWIM relaxed for a little bit, trying to tell if the insuffulated line did anything much. +0:10 A little sweaty, a little warm, very nice and a happy time. +0:30 SWIM guesses the gel-cap is dissolving in his tummy now. Everything is happy, and enjoyable. It reminds him of a low MDMA dose...except he is horny! OH SO HORNY! +0:45 I am thinking a lot about women. New people he has met, and the next steps he needs to take...to get one thing. This isn't a normal mind-set for SWIM, and it's unusual. MDMA doesn't get him this aroused. +2:30 Come down from the experience. The majority of the time was spent daydreaming about women. It was a very pleasent state, but given the cost of the substance, probably not worth it. There is a huge desire to redose and experience again immediately afterwards, and staying with you for several hours. SWIM intends to dose sometime again, and have sex during the experience, so look forward to that review. In conclusion, however, I don't feel he will be making this purchase again. It wasn't horrible, but it wasn't great. Nothing to write home about, but nothing to not recommend. It was...so-so. Maybe SWIM's feelings will change after some rough sex on this chemical. Potentially addictive. I feel like he could blow through the entire 500mg tonight... Is there a tolerance for this substance? I know close to nothing about chemistry, but Erowid refers to this is bk-MDMA. Would someone test positive for MDMA after taking this?
