Thanks to SNS for letting me try out a tub of. Below is my initial impression, though to be honest I haven't used a lot or very often.
Focus: 7/10 - This definitely helps me to regain attention to my work and also snap out of the 2PM duldrums. It's not a heightened sense of focus though, just pulls me back to focusing on work when my mind wanders.
Energy: 7/10 - Good energy, I don't feel tired mentally or physically, but the sense doesn't last too terribly long IMO. In the evening about 4 hours or so I'm getting tired. I'd like it to last a little longer.
Mood: 6/10 - No real significant boost in mood that I can tell other than a little reinvigoration. I wish some of the nootropics would give me a better sense of well being, but amines seem to do a better job for me.
Taste: 6/10 - taste is pretty decent, but not what I'd say is something I'd rush out to drink.
Overall: 7/10 - While a lot of people rave about Focus XT, I only think it's giving me average results for focus and energy. I'm hoping with more use it'll have a cumulative effect and increase effect. I need to get more consistent in using it though.
