This is an interesting supplement that I have been taking for a month now.
I started taking it before bed to help me sleep. Ever since I took them, I have been having insanely vivid dreams! I can remember what I dreamed about even hours after I wake up. Also, I found it easier to wake up in the morning.
I thought I could benefit from increased levels of growth hormone, since I like to lift weights. I did manage to reduce my body fat percentage from 15% to 13.3% while taking this, but it is hard to tell whether or not GABA supplementation played a role.
