Mass Gainer

Our most popular weight gainer formula designed for serious bulking, containing over 500kcal per serving including 66g of carbohydrate, 5g of leucine, and 40g of protein from slow and fast release sources.

When it comes to building muscle, working out is only the first part. Your body needs protein to build new muscle, as protein contributes to the growth of muscle mass. So our Mass Gainer formula is loaded with a combination of protein from multiple sources, high quality carbs and added leucine – and it’s available in a selection of incredible flavours.

Each serving of Mass Gainer gives you over 500kcal in a blend of proteins and carbohydrates. By using a combination of 40% whey protein concentrate, 40% milk protein concentrate and 20% egg white powder, your body gets a range of proteins with different rates of absorption, and we use ultra fine Scottish oats rather than sugar-based carbohydrates to give you a high quality energy source while you gain. And to top it off, Mass Gainer contains 5g of leucine as well.

The Purpose

Mass Gainer is ideal for anyone looking to increase their muscle mass and promote weight gain. If you’re on an intense bulking programme, struggle to put on muscle, or want an easier way to pack in the calories every day, this is the formula for you. And if you’re looking for a dairy-free alternative, check out our Vegan Mass Gainer (it’s soya and gluten free too).
