it is not the caffeine though. i can have coffee containing that much and not much will happen. there is many more stims in hyde. there is a pre being tested right now that has 190mg of caffeine per scoop, you would except people to use two scoops. most are using half, saying one blew their mind. no yohimbe or amp, dmaa or anything like that either. just strong dopaminergic and serotonergic modulation. of course norepi, acetylcholine etc. are also increased but it must be the dopamine and serotonine. one serving is strong enough for me and i can take extreme periphera stimuation due to taking an inhibitory medication. this stuff is very centrally active. blablabla, hyde was not so strong because of the caffeine. is that a new version you posted? large dose of nmt, citrulline-aspartate, aspartate is an excitatory neurotransmitter ad octopamine is a medication as far as i know. it definitely looks like more of a stim than strong coffee ;-)
