I don't think so. I've never felt any such effects from methylone, and trust me, i've done my share - counting probably more than 75 times.
It's a great drug, but it's not MDMA. Nor meth. It is, like many others, a unique experience, milder than MDMA, but still with a lot to go on in my opinion. It also seems less toxic to the body.
Always take it orally. Snorting, pluggin etc. doesn't do it for me, and has uncomfortables to it.'
My favorite dose lies between 150 and 200mg. 100mg gets me in a good mood too, but over 200mg is just too speedy.
Personally, I keep it to one, maximum 2 redoses, because beyond that, the side-effects become more apparent. (overly speedy, loss of appetite, insomnia, jaw clenching, tachycardia).
I find that a few days of preloading with 5-HTP enhances the experience, and that there is typically no Tuesday Bluesday (as with MDMA).
By the way - if your product is brown/orange-ish - clean it. It's not pure.
Only if it is slightly off-white (almost not visible, otherwise clearly white) crystals or crushed crystals with a tiny smell that leads your mind towards lemon or citrus - then it's clean

This was 99,3% labtested from an independent source (i know everyone can say so but --)
Have had the brown stuff too, but it's not really the same.
