There is little to no paranoia from 3-fpm in the lower dose range which for me is 30-80mg. I typically wont get it unless im dosing 150-200mg. I always purchase a benzo though to go with it just in case because I pretty much always take massive doses for euphoria rather than taking small 40mg doses throughout the day. If I want minor stimulation I'll just drink some caffiene. 3-fpm is a very clean stim though when used in reasonable doses.
I found 4-mph to give paranoia in the 30 mg dose. I only used it twice and the first time I ended up doing 3-fpm before I had enough time to gauge effects. The second time I took 2 15 mg pellets and got stimulated but it had zero mood lift and minor paranoia. I didn't like it at all. Who knows if it was the batch or what but I can't see how so many people like it. Just like MPA seemed to be pure stimulation and no euphoria some claimed to get euphoric from it so I guess you never know.
