I must agree that it looks too good to be true, and it would be great if someone else would try it and tell us the results, but why the doubt in the author's claims? They do list it's "Hilman coefficient" , where it appears a lower number means better dopamine re-uptake inhibition, why do you doubt their data? True it might not be a local anesthetic, but the euphoria would be I think indistinguishable from coke.
