for the first part of what u wrote. u didnt understand what i said. its legal for rats. aka research chemical and hence u can buy it for research purposes without problems here in the US. i assume the OP meant that he did not want a "stim" effect as in didnt want to feel stimmed out and wired. im not sure if youve used it personally, but it had no such effect in me, my gf, or my gym buddies. im not sure if im allowed to link to other forums but there was a discussion on another forum about how it makes a lot of people tired, but one guy said it kept him up. the half life is 35 hours, so if it did "stim" you up i imagine it would be a terrible experience. depending on how you wana define stim, it will increase heartrate and make ur hands shake if you dose high but its not like a ephedra/caffeine super awake feeling as far as ive observed and none of my buddies have had any trouble sleeping while dosing in the PM.
OTOH, lean xtreme seems to also be popular. or cortisol modulation
