Yeah, I agree with you a bit. Except 4-fa does have a lot to do with serotonin release. a-pvp is just a perverted potent inbred love child of methcathinone and meth. Its euphoric a bit, yes for maybe 10 minutes. But theres no "fun ego boost "like coke, or even methamp or amp. And just because a drug makes you want to redose, doesnt make it similar to coke.
Again, everyones different. I can totally understand how some people would love this, no doubt. However, after vaping something like 3 times over the course of 5 hours, I definitely instantly felt as though I have been up for 3 days straight, paranoia, etc etc. Definitely not a balanced chem. It will help you forget about your problems in life, but definitely wont make them any better

I will also mention, it is extremely more-ish, despite its positive and negative effects. Any drug that can boost DA (and I guess NE) so fast like that is sure to make you fiend.
More like a cocaine experience than meth, but lasting about as long as meth. Would snort again.
. I personally find this nothing like cocaine at all. The high is completely different, the duration, the rush, the mental head change, the physical effects. The only similarity I find between the two is the urge to redose eventually. Its definitely a lot closer to meth in terms of effects, but still not the same in a few ways. This is what I describe as dirty foggy stimulation. coke is clean fun stimulation, because its more than just stimulation... its an anti depressant (I know thats a stretch but you get where im coming from)
