As stated in an earlier post, I am so far a big fan of the AI- last night I tried AI Highpro and was not a fan- where as it is supposed to provide a deep and restful sleep- I woke up thru the night with severe cotton mouth, and kind of a groggy haze when I finally woke up for the day. But maybe give it a try, supplements do effect everyone on a slightly different level. It just doesn't work for me. So far in this trial with AI sports I am 50/50. Can't complain! Tonight I will be trying AI , lets' see how this bad boy boosts my already pretty high sex drive! I will let ya know tomrrw!
