With their Pre-Wkt range PhD Nutrition have elected to design three different products covering just about any workout need. Their Pre-Wkt Perform is devoted to improving performance while Pre-Wkt Burn is a preworkout designed principally to boost fat loss. The final one in their trinity of new products is Pre-Wkt Pump and like the name suggests, this is the one for those who love to train for the kind of roadmap vascularity and engorged muscle pumps that are sure to catch the eye of other gymgoers.

Endurance Focused Formula

Trialling a few samples of Pre-Wkt Pump it became clear immediately that this would work best for high rep, short rest interval style workouts as well as evening workouts where you would not be advised to use stimulants.

Pre-Wkt Pump contains a number of ingredients which support enhanced oxygen and blood supply to muscles including citrulline malate, AAKG, as well as the endurance promoting trimethylglycine, also known as betaine anhydrous. Perhaps the most interesting inclusion is Oxystorm®, a trademarked ingredient which acts as a natural nitrate. Nitrate based supplements have a great reputation for boosting vascularity and endurance so it is great to see a British company introducing an ingredient which is new to us, and certainly something of a rarity.

If you are looking for a stimulant free product then this is a good option although we must stress that the dosing of the citrulline malate is on the low side here but it has enough other nutrients that will combine to make it an effective aid to endurance performance.
