It is early to decide, but it appears to have helped my wife. The site is great! Shipping was quick and painless! Looking forward to exploring more options from Onnit!

I took the supplements as recomended, for 15 days. I personally did not notice any increase in my ability to focus or concentrate. No side effects either. May work for others

After taking it for a few weeks, I've noticed better memory, focus, and what I would call mental energy. Good product that I definitely recommend. I've tried other cheaper versions of this product and they do not even compare.

Gives lots of energy when taken correctly! I really enjoy the results I’m seeing. Both my gf and I have been using it for 3 weeks straight and plan to continue.

I didn’t notice anything until the first bottle was almost gone. But taking this daily has been a game changer. I was looking for an alternative to pre-workouts and definitely found one! Simply clean energy, tons of focus in the gym too.

This absolutely works! By day 2 I thought I felt more present and by the end of the first week I was absolutely convinced. I just placed my second order.

After reading the bottle and it says take two capsules at a time, I felt like I was going to throw up all day. I told myself that going forward I will only take one at a time but I haven't been very eager to try it again since.

I love it. I take 1 on days I train jujitsu have school or work both jobs. It wakes me up, helps me focus, I feel great. Taking two sometimes burns me out, taking them everyday is not recommended

I went into this purchase with open arms because I have heard Joe Rogan speak very highly of this product. Unfortunately, after two weeks of using as directed, I have determined that I did not get any result from the supplement.

I got three bottles of this thinking it was going to do what Joe Rogan says it does to him. But i think the B-Vitamin is what kicks in for me. Am i quoting Shakespeare by memory? No. So i'll keep taking it until its gone and we'll go from there.
