got it on christmas eve day...tried it in the late afternoon...it is something you take during the day as a "mood enhancer", not before bed...i can tell you it made me pretty loopy and a little speedy...something hurt my stomach...i don't know if it was the renew g or just the stress of christmas, or something i may have eaten (because i ate some reall junk on christmas eve"..my friend took it too, and said he felt like he was almost rolling....i will give you more info later, but the stuff seems pretty legit...it kind of gave me the xenadrine type buzz, but more of a head thing then a body....weird
