I have purchased several different nootropics and products to stimulate my mind and body. I knew that the two were connected but could never quite keep that equilibrium for long. I started to feel it with phenylpiracetam mixed with aniracetam and piracetam but I think that I needed more choline for that and started to feel a pain in my side. When I got my Liftmode products I tried them and there was no immediate response. But the very next day I could see the changes taking place. I leaped out of bed. This is significant because I normally drag out. But after I started using the yohimbine hcl, man o man. I can't describe it in words but for the sample it is only 6 or 7 dollars. But I guarantee you it will change your life!
