Sorry guys, yea actually I have been wired since about 1:30 and still feel it. This stuff is no joke. 1 capsule would have been a good start for me. After about 30 minutes it started to kick in then hit hard after about an hour. I had already had my workout earlier today so I had to leave the computer because yes I did feel like my avatar and go mow the grass, then wash my car. For 3 hours there I felt like I could run a marathon. Breathing seemed easier, and just felt on a different level. Honestly I was a little jittery however I think It was because of taking both capsules at once. I have not used any stimulant like this in a while and they not part of my normal supplements however this one could be the next addition. I feel leveled off now but still have good energy and feel good. Taking this first thing in the morning to kick start the day or before a workout would be killer.
