Reflex Instant Mass Pro:

Instant Mass Pro 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 Pro weight gainer is different.

Instant Mass Pro is not a typical weight gainer. It is an ultra high quality weight gain product made with a near perfect 50/50 split of protein and carbohydrate.

Instant Mass Pro 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.
