For athletes who train hard who need a superior-quality post-workout supplement, look no further than our hydrolysed whey protein isolate, and our own proprietary ISO Whey GF-1 blend.

In that post-workout recovery window, you need to give your body the fuel it needs to grow big and strong so it can repair and develop your muscles. Hydrolysed WPI is the answer. This form of WPI absorbed extremely rapidly by the body thanks to the addition of tailored enzymes during manufacturing that pre-digests them, making it easier for you to absorb.
