I work in construction and train in martial arts. I purchased the whey protein and the recovery smoothie, I did notice a difference when it came to recovery after taking the recovery smoothie after my training sessions. I used the whey with my oats in the morning every morning during a fight prep and sometimes after training. I did notice I kept quite a lot of muscle on still and shaved off fat, this is not a byist review either their whey concentrate has got to be one of the best tasting ones I have ever tried. Thank you for your service, I would definitely be keen to try other products in the future. For other buyers out there, be willing to pay a bit more to get more out of your supplements.
