i havent used p83 too much, what kind of results have you gotten?
i love p79, its like supersizing your fries, it makes you feel more. anything i use with is feels amplified. ive used it by itself at the gym and as soon as i get little hyped, its like mario kart when youre going fast then you grab a red mushroom, youre instantly faster
thats the best way to explain it. i know some people said it can make you feel depressed or self conscious. personally i think it just makes you feel more of whatever is there. i didnt feel self conscious at all when i used it by itself at the gym
p74 is also really good.(u can make a great mix out of ammo, p79, and p74) i use p74 and IS when I have to write papers. the mix wakes me up and gets me focused.
ive been trying to find p75 which i heard gets great results, but i havent tesed it myself. dont count on finding it anytime soon
ive heard good things about p86 as well. i have it, but i havent used it much either
definitely get p79 + p74, you wont be disappointed
