Great boost of energy but not too much caffeine im sensitive to caffeine because I dont drink alot of coffee. Works great though a good boost for after work workouts or get you going for early morning workouts.*

Both taste great. Rainbow blast is more subtle but that is preferred imo. Good energy, good pump - mixes well with water and not too intense. If anything I could go for a little more caffeine but 0 complaints!*
