Phenomenal price on this product and for me, just the right amount of everything since I stay away from high stim products these days. I don’t usually go for lemon lime or purple drank (grape) flavors but these actually taste very good and mixes easily. Rule1 has always made good products in my opinion and shipping was quite fast.*
