Never tried MPA or cocaine, but seeing as 4-FA has quite a bit of serotonergic effect in comparison to the others, I would say it's better if you want more of a "roll" type feeling.
I've had 4-FA countless times. Eventually if you build up a tolerance and dose to often, it loses a lot of the magic type feelings and becomes more of just a speedy type feel, and not always enjoyable either..
So would you say 4-fa is like a cocaine high but more euphoric and with tolerance issues? I'm looking at recreational usage so i guess MPA is the inferior substance.
Yes, this. Not like cocaine really, but this is based off of only reading of cocaines effects.
Cocaine feels more like a straight stimulant with speedy like effects, though it has "major" euphoria for a lot of people. The "god like" feeling.
4-FA is like MDMA and amphetamine in the sense that you will feel empathetic, with the lovey feelings and opening up to others, while also being clearly stimulated and speedy. Just not as strong as MDMA in regards to empathy.
I would say 4-FA is what you should go for. Cocaine is a very short lived, fiendish high. Also very taxing on the cardiovascular system, not to mention highly variable purity. Cocaine may provide more euphoria than 4-FA, but for a first timer of 4-FA there should be plenty of good euphoria. I certainly know I loved it the first time I tried it, and this was me seeking a 4-MMC replacement. Closest thing I found.
In the future, please look up experience reports, effects profiles and mechanism of action to draw your own conclusions, or post in the respective substance's megathread for further information.
