Complete Mass™ is a calorie dense weight gainer, designed for real hard gainers. Not only does Complete Mass™ contain over 500kcal per serving, but it is crammed with multiple sources of protein and is fortified with amino acids such as leucine. In addition, Complete Mass™ tastes so good that you’ll look forward to each and every shake.

Complete Mass™ focuses on quality ingredients — not just cheap sources of protein and sugar. Even so, Complete Mass™ still packs a massive 40g protein and 66g carbohydrate per serving. If you compare the sources of protein and carbohydrate to your existing weight-gainer, it’ll further highlight the quality of the Complete Mass™ formula.

For those trying to increase muscle mass, it is clear that the body requires additional calories. After all, simply speaking, calories consumed must be greater than calories used to promote weight gain. It isn’t always quite that simple though. Generally, nobody trying to put on mass does it with the aim of getting fat. In respect of this, Complete Mass™ has been formulated for those with higher calorie requirements, but who want a quality formula that isn’t packed with cheap sugar. The inclusion of Ultra Fine Scottish Oats then, rather than sugar-based dextrose or maltodextrin, ensures that the body has a sustained release of energy, while also helping to regulate blood sugar levels.


  • Calorie dense shake, over 500kcal
  • 40g of protein from multiple sources
  • Slow and fast release protein blend
  • 66g of Low GI carbohydrate
  • 5g of Leucine per serving
  • Contributes to the growth in muscle mass
  • Contributes to the maintenance of muscle mass


Complete Mass™ provides you with over 500kcal from ideal sources of protein and carbohydrate. Complete Mass™ utilises a slow and fast release protein blend so that your muscles receive a rich supply of amino acids over an extended period of time. Complete Mass™ utilises a low GI source of carbohydrate as an alternative to sugary sources of carbohydrates you may find in other products, such as dextrose and Maltodextrin. This will help to prevent fat gain alongside increases in muscle mass.


Slow and Fast Release Protein Blend

A multi-protein blend of 40% whey protein concentrate, 40% milk protein concentrate and 20% egg white powder delivers a complete collection of amino acids at different speeds of absorption. All three of these protein sources are popular in their own right for strength athletes, and are ideal for promoting weight gain. Unlike many other brands, we are happy to detail the percentage contribution of each protein source in this product — we have nothing to hide!


Complete Mass™ has a market-leading 5g leucine per serving. Often, products with a protein blend are lower in Leucine (as whey is richer in Leucine than other protein sources); to make up for this, Complete Mass™ contains added Leucine.

Ultra Fine Scottish Oats

Oats provide a healthy source of carbohydrate that fuel the body with a sustained release of energy and additionally are a great source of healthy fibre.


Complete Mass™ is ideal for anyone looking to increase muscle mass and promote weight gain. Complete Mass™ is ideal for hard gainers and those who struggle to put on muscle mass.
