This herb is supposed to aid mental focus, an action that is weakly supported by research (Auguet, et al 1986). It is supposed to improve blood flow to the cerebral cortex and help alertness, as well as enhance ATP synthesis and glucose uptake in the brain (Gebner, et al 1985; Allard 1986; Hindmarch 1986).
Keeping focused during training is crucial to maximum gains, as we all know, so this product is used by some bodybuilders. Unfortunately, it has a side effect that makes it useless, in that it gives terrible headaches. Maybe give it a try, but if you get a headache, it's not worth using it again.
