Pero Instant Natural Beverage is a 100% natural and caffeine free formula. It will not cause sleeplessness, high blood pressure or stomach problems, because it contains none of the stimulants that coffee and tea contain.

DIRECTIONS: To enjoy PERO® as an instant hot beverage, place one heaping teaspoon into a cup. Add very hot (not boiling) water, stir. Add milk and sugar to taste if desired.
