I just got my first tub of Kwick Karb from Nutraplanet. Really I don't know what I should do as far as a serving size. I usually use Primaforce, but I wanted to save money and support my favorite e-tailor. Usually I get my tub of whatever I purchased and put it into my paid version of Fitday straight away. With this tub of Kwick Karb I seem to be having an extended brain fart.....
