Sustained Release

Sustained Release is what you get when you combine whey, casein and milk into a single protein supplement. Doing so allows you to feed your body for the next 8 hours with a steady supply of amino acids and nitrogen - perfect for creating an anabolic environment!

This makes sustained release protein great for increased satiety (keeping you feeling full) AND good for giving your body the amino acids you need in the short term.This is an excellent choice for snacks, meals and post-workout shakes when you can't eat a full meal.
