Quick Overview


Instant Mass® is a weight gainer that totally redefines the category


Weight gainers have always been popular with bodybuilders. We believe that weight gainers should contain ingredients beneficial to overall health as well as helping you gain weight. Many of our competitors use sugars to provide the carbohydrates in their weight gainers. Read on to see why Instant Mass® weight gainer is different.

Instant Mass® is arguably the best weight gainer product you can buy on the market today for three simple reasons:
  • It contains more protein than ANY other brand.
  • It contains low GI carbohydrate in the form of organic oats and barley, where other brands will use sugars such as maltodextrin or dextrose.
  • Every batch is tested for protein content, protein is one of the most important foods given its contribution to growth in muscle mass and maintenance of muscle mass.

Instant Mass® weight gainer provides 54 grams of high quality protein per serving. An amazing high quality blend of ultra filtered whey protein concentrate, milk protein concentrate (80% micellar casein, 20% whey protein) and Egg White Protein Isolate. Instant Mass® contains our exclusive Muscle DriveTM complex, a combination of the amino acid glutamine. We also include Digezyme® digestive enzymes and Lactospore® probiotics.

Instant Mass® was the first weight gainer in the world to use an exclusive blend of organic oats and barley. In fact, it is still one of the only weight gainers you can buy today which offers a low GI, organic source of carbohydrate rich in naturally occurring vitamins, minerals and dietary fibre.

Instant Mass® weight gainer contains vital minerals. Couple this with added antioxidants and you have a nutrient package that few can better.

Serving Suggestions: Take 2 measures (approx 25g) and mix with 300ml of water or milk in a blender or Reflex shaker
