The ability to crush rocks, indiscriminately of tendon wear or sluggish recovery!
I train hard and this stuff gives me the nutritional boosts I need to keep my tendons happy and recovering well.
The Endure X is a fantastic product as well. I used to be a heavy gym rat and have tried a number of pre workouts. This if by far preferable, and the direct forearm recovery between hard burns is noticeable.
Will continue to purchase as long as it's available.
