I'm taking PowerFULL right now. I decided to only dose it once at night because i always have carbs in my system Pre-workout.
I can't say it's helping my sleep but i am starting to have dreams which i normally don't so i keep taking it. I'm playing with the doses trying 2-5 caps a night.
I have a bottle of AI's HGHPro coming and i honestly can't wait to give it a try after im done with PowerFULL.
I also like that AI has GABA.
I actually looked up GABA earlier today and found it may actually be fairly bogus, possibly works if it is taken before working out. Regardless of that, i've taken it stand alone before and it has helped with sleep.
