My son, Skyler, is an offensive lineman on Paloma Valley’s Varsity football team. I bought this for him to try to keep his energy up (especially in the 4th quarter!). He noticed the difference right away. It definitely helps him go head to head against those Defensive lineman play after play after play. After the game he noticed he was not as exhausted as usual. He is now passing them out to our whole O line! Watch out Sunbelt League! Here come the Wildcats!!!!
