Mass & Size Builders

Here at Peak Body Nutrition, we offer a wide choice of protein powders and protein bars. Designed for those who want to build muscle mass and body size, these supplements can help you maximise results in combination with your own dietary consumption of food.

Our range of mass and size supplements have all the required protein you could ask for in order to increase your strength and endurance without compromising any meal plan you may have in place.

Amongst our range of protein products, we offer whey protein. This has been determined as the most vital type of protein for pushing protein synthesis. As it is made from milk, it contains a large quantity of amino acids, which are ideal for repairing muscle tissues. The repair process will in turn see an increase in the muscle you are building. Why protein also has the advantage of being quick to digest, so it reaches where it needs to go with efficiency.

As well as protein powders, as part of our mass and size builders’ range, we provide products such as protein bars and bundles that contain various products for building mass. Whatever muscle mass supplements you desire, they include different flavours to suit your taste, making it an enjoyable part of your day.

Also known as a mass gain, protein supplements such as these also contain calories to promote weight gain, so it’s important to take these with a balanced diet, along with exercise, in order to achieve and maintain your desired results.
