You told him to add the that too the other shit he was already taking fuckface, he said he was taking the crap you claim is amphetamine.
BTW, calm down smart guy, it'll be ok 
Yes, because what he was taking is green tea and caffeine, as i told him.
L-Tyrosine blocks noradrenalin, so any fatburner stack that works through thermogenesis and adrenalin reaction will be more effective at lower doses if you add L-Tyrosine, because it blocks the stuff that destroys adrenalin.
L-Tyrosine uses the same transporters as BCAA, so it is good to supplement, especially if you're cutting.
Learn your stuff before you bash people. I am just giving people advice here how to supplement smart.
Not wasting money due to wrong consumption, not risking your health by taking some medical drugs nobody has researched (aka designer steroids) and other stuff.
If you want to start a fight, do it somewhere else. If you have good advice, post it. If you're not sure or have just hearsaying, better keep it to yourself if somebody else knows it better.
