What is your intent?: Majority do not, but depends why you are taking it. If just want protein, most are "just" protein. If nutritional or stacking or alertness seeking, then unfortunately need to check labels. May get symptoms from other stimulating nutritionals as well, though, so start low(-dose) and see how you tolerate them.
