ive been using mx256 for some time now.. just to see how it goes. as i understand it, it’s basically p104
ive been testing it from anywhere between 50mcg (5 sprays of mx256) and 75mcg (6 sprays mx256). i researched the dosage before i put it on, and 1 spray of mx256 is 12.5mcg
i found that this phero is basically very social and a feel-good type phero. nothing very sexual though.
before i did the real testing, i sprayed 2 sprays on myself the night before to gauge some self effects. i was very happy and all smiley. i was a little stressed out from school so it was nice 
i had nice dreams
i wore it out to class for 2 days in a row. people seemed divided on the scent. some really liked it, some said it didnt suit me at all. im personally not a big crazy fan of the smell.
i just remember finding everything funny. i was very smiley and people asked me if something nice happened. (not that i look angry all the time but i dont smile all the time neither 
)
people found all my jokes really funny. and i must admit, sometimes i did make some pretty bad jokes. haha
more people tried to make small talks with me. the people that i usually dont really talk to or do the cursory nods stopped by my desk to ask how i was doing etc. etc.
one of the professors stopped me on the way out to comment that i looked really happy. i mean, she’s usually a very personable professor, but we do have a HUGE class.
from what i experienced, i think it could be dubbed as one of the sunshine series. other than me being really happy and others around it, nothing seemed sexual and some of the hits were very very subtle. i personally would like to try this in an unscented or neroli scented version to even out the playing field. (i found that some people really dont like the smell and actually commented on it the next day)
def. give p104 a shot if you want to be happy sunshiney
