I wanted to order the AT-2 and Lean Extreme. I wanted to make sure these are non-stimulant since I am stim-sensitive. I've read up on both and feel comfortable with the Lean Extreme but am a little concerned about the ingredients in the AT-2. Some say it stims them out but I've read other views where they say it actually slows their heart rate down and relaxes them. What's the truth?? Thanks.
