I don't think so. Mephedrone is more rushy/speedy while Methylone is more lovey. here's some discussion http://www.bluelight.ru/vb/showthread.php?t=415534
I only have experience with methylone, its not even really lovey. You just feel content, sex is enhanced on it for sure, but therw is no push into a lovey/good mood like mdma. There is like a sweet spot with it at 150-175 mg , good to chill , play some softer music, I've always wanted to go to the beach on it, not really party material like MDMA though. If you take a high dose it will be rushy for a half hour and feel what I would call a hollow mdma (it has the energy and feels good but doesn't warm my heart like MDMA) I think it really shines at that medium dose. Mephedrone might be more useful for parties I've heard you feel pretty light headed and can get more energetic.
At 250mg I was texting people i shouldn't be, telling my friends how much i love them, and offering them hugs and back rubs. I found it to be superior to MDMA in many ways; lasted longer (though the stimulation lasted too long imo, but that can be useful as well ) and was less 'explosively euphoric', but like i was still rubbing my whole body and groaning and rolling my eyes around in ecstasy. And it had ZERO GI side effects, unlike MDMA where I tend to get diarrhea right when I'm exploding which is annoying.
...that sucks I've never had gi problems with mdma. I have this weird buzzing tension on higher doses of methylone even like an hour into it, where the closest thing I can compare it to is laying on your arm or leg for awhile and then get up and it feels asleep. I can dismiss it somewhat but its definitely noticeable. I enjoy the stuff and I find it easier on the body and mind then MDMA but I find the mild psychedelia and 'magic' of MDMA to be lacking. Its a good stimulant and a matter of personal choice
I have never tried MDMA or Methylone, but Mephedrone was amazing. I spent 5 hours telling my deepest secrets to people I'd only just met and when I was alone I ended up calling everyone in my contacts until I eventually ran out of credit. Definitely a great "love drug", I didn't really find it very speedy and I could just sit there and chill, but the euphoria and empathy were amazing. Also, after 2 days of binging on it, no comedown, whatsoever.
