Sharp brings clarity and focus to my morning. If for some reason I forget to take it I definitely notice. It’s an autoship for me now !

I ordered both stim and stim free, but SF is my go to taste wise! Both are great but SF the flavor is spot on- fresh, fruity, sweet! My go-to for an afternoon pick me up. So good I have to limit myself to 2 servings a day lol
