I have been doing alot of research on these two, since i am incredibly interested in trying one of them. It'll be the first RC i do that isnt psychedelic and i just want to make sure im picking the right one. With Methylone there is a longer duration but i dont think i would want to insufflate it and with mephedrone the high seems like it would be better then the latter. im just curious as to which one you guys would choose or prefer.
From what I hear mephedrone is more stimulating and more in your face euphoric, methylone is more relaxed and mellow, mild stimulation and a relaxed euphoric feeling. Mephedrone has had a small number of deaths attributed to it, methylone has not as far as I know. Mephedrone is also fairly addictive stuff, I know a few people who are pretty addicted to it, probably about as addictive as ketamine. I would say on the soft-hard drug spectrum, mephedrone is much nearer to the hard drug side than methylone is. I also imagine you would probably like mephedrone better, but every coin has two sides so keep that in mind.
Oral 250mg mephedrone is definately strong experience. Nasal 250mg mephedrone is a litlle overdose IMO
