I just started a T2 and OEP stack today. I took oe of each when I woke, and one of each 7 hours later. I am full of energy and feel like I could run 50ks without stopping. I have better concerntration and have not felt the need to eat all day. During the day I usually snack ALOT but today all i had was a shake for breakie and a hot meal for lunch. I know it has only been on day but I love it. You definately heat up
