Cobra Labs, the people behind the highly succesful The Curse pre-workout and The Ripper fat burner have released their latest product, Shadow X. Like The Curse, Shadow X is a powerful pre-workout delivering energy, strength and mental focus.

There are no proprietary blends in Shadow X which is refreshing to see, with each ingredient dosed specifically for maximum results. Split into three matrices (muscle power, muscle pump and mental focus), the ingredient that stands out is the Olive Leaf Extract. It's not something we see in your normal pre-workout (aside from The Curse) and the reason behind its inclusion is to help lower blood pressure and it can have a benefit for your immune system too.

Aside from the Olive Leaf Extract though, the other active ingredients are your standard pre-workout ingredients such as Caffeine Anhydrous at a chunky 350mg dose that will really get you moving, Beta-Alanine, Taurine and a healthy 2g of Citrulline to give fantastic pumps, vascularity and muscle endurance.

Shadow X is another great offering from Cobra Labs and works effectively to improve overall performance, but comparing it to other pre-workouts such as Driven Sports Frenzy or Craze we struggle to see where it offers a unique pre-workout experience.
