Bests & Worsts Reviews from Amazon

I took before Jiu Jitsu training, another before a sparring session and a few times before work I didn't notice any difference in memory or focus. I agree with the guy about diarrhea, maybe not 12-15 times a day for me but a significant increase in my toilet visits is about the only thing i noticed. Everyone is different but this was my experience with Alpha Brain. I also consume a massive amount of coffee and water throughout my day so this may have an effect on the products benefits. Try it if you're curious, like i said this was my personal experience. Everyone's body reacts differently.
