Provides a very nice edge. Definitely a smooth and precise push. I like it, but must be careful with additional caffeine. If you are a coffee drinker, you might wish to reduce or eliminate coffee when taking. I add a bit of theanine with any additional coffee. But highly recommend you try Focus and find where it fits in your program. Nice product. Especially like how the taurine and tyrosine combine.

I’m still getting used to it. I had to start at a lower dosage because of the amount of caffeine in it. Building up to the recommended dosage. So far so good

Wonderful product!

A great supplement! Gives me energy and focus without getting jittery.
