I’ve been using this for a few weeks now, mixing it before my morning workouts. The Concord Grape flavor tastes great and isn’t too sweet. I noticed the energy kick from the 100mg caffeine is clean and sustained, not jumpy like some pre-workouts. The powder dissolves well in water, and I appreciate the low-calorie aspect. While it’s a bit pricey at $115, the quality feels solid. Honestly, it’s better than that rayo vallecano vs lech poznaÅ„ match I watched last weekend – at least this gives me consistent energy!
