I am looking for m3thylph3nidat3 or some kind of analog or similar substance for ADHD, preferably extended release. I live in Spain, and I don't really have a big budget. I've heard about 4-M3TMP, but it seems that its action is very short. Also, I don't know where to get it, since these R$Cs are not as readily available as they used to be, and I don't know any reliable v3nd0rs for Europe. Any help would be appreciated.
