Someone I know has high expectations for this, probably derived from 2-FA and 4-FA and maybe 3-FMC. Thinks it is gonna be a very good one.
Personally I don't really see it, the SAR for ortho/meta/para substitutions on amphetamine don't make a whole lot of sense to me even though it might really not be that difficult. A while ago I thought I read somewhere that 3-position substitutions were a no-no, but maybe I'm wrong. Is there reason to think 3-subbed amphetamines are toxic? significantly more toxic than their positional isomers?
2-FA reminded me of 4-FA, which is not surprising. But it did leave me wanting more, and really seemed to last a lot shorter, though like 4-FA it had the effect of trailing off making you unable to really say when you transition back to baseline. In other words: it lingers. 2-FA did make me redose somewhat compulsively, not exactly because the reward was so big but it seemed to be right around the corner but never really came.
4-FA starts off similar to MDMA for me but much more clearheaded, not psychedelic either. Then after a few hours it changes to something similar to dexamphetamine IMO. Or somewhere in between racemic and dex (so 75/25 that would be).
2-FA reminded me even much more of dexamph. It didn't really seem to have serotonin activity like 4-FA at least seemed to have. Well on the other hand it doesn't have to be that much, methylone is mostly dopaminergic and it still has an MDMA vibe.
If 3-FA really sits in between 2-FA and 3-FA it could be quite good, mellow but hopefully able to reach full incline, and a comfortable duration of action.
But who knows there could be something completely off with it.
Is the fluor on the ring and it's position mostly important for metabolism, kinetics, receptor interaction or a specific event at the receptor? Does anyone know? This is getting to be ADD territory so apologies. I could move my post.
