Product Uses
Recommended Usage

To maximise muscle recovery and lean muscle mass gains, ideally you should be having a high-quality protein feeds of 20-40 g every 3-4 hours. PROTEIN20 can be used immediately post-exercise or as a daily snack to meet your protein needs.

Do not consume more than 2 per day.


There are thousands of proteins in our bodies, all of which perform a variety of daily functions to promote health, well-being and performance. We must consume adequate protein in our diet so that we have the relevant building blocks to make the new proteins required for our body to function.

When strength training, the combination of lifting weights and protein intake is used to build new proteins, especially the contractile proteins. This repeated muscle damage and protein feeding results in muscle growth.

In relation to endurance performance, protein intake is equally as important. In this situation the stress of endurance exercise creates a signal to instruct our muscles to make new proteins involved in aerobic energy production.
