Got this for my other half. Originally picked the apple flavour but it was out of stock so lovely customer service lady (Carly) helped me out with the Blue Raz. My other half takes this pre-workout/training, it helps with soreness from a healing injury and makes the workout easier. He trains in rugby and mma so does a lot of high intensity stuff. Top notch product and service!
