"I started using this before early morning client sessions when I need to be sharp but don't want to be bouncing off the walls. The clean energy is perfect for the job. No shakiness, no anxiety, just dialed in. I looked into the ingredient list and seen Alpha-GPC, B-vitamins, ginseng, and it got me HYPED that this is actually a well-formulated product, not just caffeine in a fricken tub. I've already recommended it to a few of my clients who deal with mental fatigue and they've all had good things to say. Worth every penny."
