VANIILA AND CHOCOLATE PROTEIN???
did you try adding like 1/4 cup of milk to your coffee first? I find that it is the TEMPERATURE that often makes the powder clump up and do NASTY things in my coffee. If I add some milk fist to get the temp down....NO Problem. I buy EAS from Sams and mix it in my coffee every morning and have had terrible issues when the coffee is HOT.
