Shameless bump of an ancient topic but since I could not find a propper anser to OP's question and the searchbar stil redirects me here:
Fluorofinil is simply Modafinil with two extra fluor atoms, compared to Modafinil the effect are pretty much the same, it's about equipotent in weight , it's duration is 5 hours as were Modafinil lasts about 12 hours and both substances are relatively expensive. It has been sold under the retarded name 'Modafiendz' and I believe it is nowadays often referred to as 'FL-Modafinil'. Keep in mind Modafinil has very mild / hardly notable effects and can produce quite nasty side effects beyond 200mg.
As for Eurocaine, this is a retarded brandname made up by (ofcourse) an English vendor and similair to bath salts it cointained a different active substance depending on wich period in time you bought it. They also seem to add Lidocaine by default to the random Eurocaine substances wich a local anaesthesia used by dentists. Needless to say, Eurocaine is cancer not worth mentioning.
I also saw 'synthacaine' being mentioned, and altough u never know what crap you'll recieve when buying a 'RC brandname', this was most commonly referred to as 3-FPM.
