Each Primaforce caffeine tablet contains 200mg of caffeine. Let that sink in for a minute. Each tiny pill contains the amount of caffeine that can be found in 4 standard cups of coffee. That is incredible, and an incredible asset that you can learn to harness for your personal energy needs and goals. Instead of buying a coffee for work or for those late nights catching up on course work you can simply take a pill and chase it with your favorite beverage without having to sip on coffee all night long. If you are in the market for a pre workout supplement these pills can provide an ample energy boost to get you to and past your fitness goals without the purchase of expensive workout mixes and chemical laden powders. If you wish to take it one step further, caffeine can ramp up your metabolism to expedite fat loss from a rigorous exercise program and diet structure.
