PhD Pre-Wkt PUMP contains the latest breakthrough ingredient technology for bodybuilders seeking serious muscle pumps leading to muscle growth activation. Containing over 2g of Arginine and Betaine per serving Pre-Wkt PUMP also contains the super-ingredient L-Norvaline. It also contains NO CAFFEINE.
So why no caffeine?- The answer is complicated in its science but simple in it’s reasoning. Caffeine acts as both a vasoconstrictor and a mild diuretic, these are both reactions in the body that are exactly the opposite of what you want to happen if you are actively seeking a muscle pump. Firstly, vasoconstriction is the narrowing of blood vessels. Arginine (which is a key ingredient for the muscle pump) is a vasodilator (expansion of blood vessels), one allows more blood into the muscle, one allows less. If you have both in the same product, you are countering the effects of both. If you want to increase muscle pumps- then don’t use a pre workout with caffeine, but always use Arginine for it’s ability to increase Nitric Oxide production. This comes back to the reason why we have created 3 pre workout products. Remember we agreed that the reason for using a pre workout wasn’t to get ready for a night out?, the reason is to enhance the benefits of whatever type of training you are doing. More blood into the muscle means more nutrients and the greater ability to build muscle. So if you want a muscle pump and are training to get bigger, don’t use a pre workout with caffeine in. If you want to perform better and lose body fat, well that’s a different story and that’s why we have created pre workout BURN and PERFORM.
