I have used the liquid product from AG guys and have been very happy with the results. I started off taking 25mg an hour before the main event but quickly relaized that it took a lot longer to fully kick in. It lasts well into the 72hr range and seems to be working best at the 24hr mark, by this time Im constantly at half mast even if I'm watching baseball. So now I will take 25mg before bed on say Thursday night and then I'm good to go through Sunday. Really an amazing product, far superior to competiton. Experiment a little bit and you will quickly find what works best for you. Enjoy.
