I just registered because I felt the need to share my experience with it. I have been a Methylone user since 2010 and with the bans it has become very hard to feed my needs.

When I learned BMDP was structured like Methylone I indulged with a large supply. My first experience with it was this:
Taste test very extremely chemical/bitter so I placed my doses into gel caps. Method was obviously oral.
0.0 mins 200mg
0.25 mins felt something couldn't pin point it but thought it had to do with something with vision.
1:00 nothing really changed except feeling light and a extremely mild wiggle eyes so I took another 200mg oral.
1:30 I could almost feel that feeling where your body wants to roll but just doesn't make that switch. I took another 150mg oral.
2:00 Still feeling what I did at 1:30.
4:00 Never made the switch to rolling and my vision (mild wiggle eye type) going back to normal off and on.
6:00 Trying to sleep but kept me up for another hour or two.
Second trial after I read as much as I could on the net. So I was convinced pretty much I just wasn't taking enough. About 1 week later..
0:00 800mg Gel cap with a full glass of water.
0:45 Didn't feel anything up til 45 minutes and like a light switch my body felt like it needed to stretch so I stood and I immediately got goose bumps, chills and I felt nearly like the come up of Methylone, a good 300mg dose. At this point I took another 600mg oral.
1:30 Up to this point I had my eyes closed most of the time just concentrating on a mild roll (wiggle eyes, chills, stretching, sweaty palms, mild grind) Then like a switch again I was rolling nice as if it was Methylone that Im familiar with.
2:00 It started wearing off pretty quickly, felt no different than a Methylone come down except it was fast and didnt really have a speed feeling. But I'm pretty sure I wouldn't be able to sleep anytime soon.
2:30 The mild roll was turning on and off but at this point it was pretty much gone for good.
4:00 Pretty much completely gone and it took me a few hours to fall asleep.
I have since then been starting with 1g oral doses and found out once I ran out of gel caps and been mixing it in some strong cherry Kool-Aid its been hitting me a bit harder and faster. I wait about 2 weeks between dosing for maximum effects, anything shorter you can tell it's much more mild than waiting it out. But 1g oral dose after two weeks gives me a strong Methylone roll but as before, its short lived. I would say two hours max. Once I took another 800mg after 1g and it really didn't do to much more than just taking 1g one time. It may be because I don't like putting a lot of this in me. I just have never put more than 2gs in a session. To me I think it would do more harm than good, that's what my body tells me. Just a after thought: once I do run out, Ive already convinced myself that I won't be reordering. I can't shake the feeling that this particular RC is putting a beating on me that I may not even realize until time has passed. It just feels more dirty than Methylone by a long shot...
