Got mine today(damn I love BN's fast shipping!), took two after a small meal just to guage what it is like....
Gave me a good
energy rush after about 30-40 minutes, didn't really change my mood at all but I really wanted to get to the gym (I was at work). Killed my appetite, took the two pills around 3pm and wasn't hungry all day, finally ate around 8pm just because a co-worker wanted to grab dinner.
Its too early to say if I would recommend this yet, I'll probably take 3 next time. Look for my review in a week or two in the products section.
