I’ve had a full bottle, and this is a steady focus supplement. It’s potent and strong for about 3 hours or more and it’s pretty good relative to other products out there’s recommend.

Day 1 I was impressed! I took 4 capsules (6 is suggested) and that’s all I needed to kickstart my day. Afterwards I just took 2 a day except when I had a lot to accomplish (work reports, meetings, proposals). I’ve been without for almost a week and I’m back to where I was before Xbrain.
