Pump Formulas

It means the brand's ingredient list contains no caffeine and no other stimulant ingredient. It describes what is not in the product, and the wording is the brand's, so check the ingredient list of the product you choose: not every product in this category is caffeine-free.

Compare the price per serving (pack price divided by servings per pack), the serving size in grams or millilitres, and the amount of each main ingredient the label states per serving. A label that lists citrulline malate gives the weight of the compound, which includes malic acid and is more than the citrulline in it; read the line that names citrulline if the label has one. An ingredient inside a complex with no amount cannot be compared.

Many pump formulas already contain creatine, taurine, beta-alanine or betaine, so check every label and add up the amount of each ingredient when you use more than one product. Follow the directions printed on each pack, and ask a doctor or pharmacist first if you are pregnant, breastfeeding, under 18 or take medication.
