Garbage
Really regret spending $75 on this product. I take as directed by the bottle. 2-3 in am 2 in pm. A few times I have become extremely tired around 4 pm. Even yesterday I fell asleep and didn't wake up until 14 hours later. I missed out on a lot i needed to do. Terrible short term crashes. Don't get any energy from it. Doesn't improve function of the brain in the slightest. Maybe it's just me but for me, I'll definitely never ever waste my money on this product again.
