UPDATE: a fellow worker of mine recommended VPX Redline extreme and after work i drink one and it works like a charm. boosts energy, puts me in a better mood, gives me stamina at the gym. i would recommend it to anyone.
yea be careful one which ones you buy. some are more potent than other and the serving size is 1/4 of the bottle or 1/2 of the bottle. didnt read that one day and drank a whole bottle of some potent shit ..... not fun, or was it?
