Ultimate Nutrition ISO Mass Gainer supplies more than 900 calories per serving. In addition to lean protein and an exceptional amount of carbohydrates, the supplement packs creatine into the mix. Creatine hydrates the muscle, which can cause electrolyte imbalance and muscle cramping, but it is widely used by bodybuilders trying to gain bulk. This supplement may contain a lean source of protein and very little fat, but it is not intended for weight loss or dieting. Bodybuilders need to protect muscle mass and supply muscles with a huge amount of protein when training hardest. This supplement will not only cause weight gain, it will cause water retention.

Product Features

There are two different times in bodybuilding – bulking and cutting. During the bulking phase, bodybuilders push the muscle harder than humanly possible. Carbohydrate stores are quickly used up and the body turns to fat and protein sources, like muscle, for the energy it needs to keep going. This is not what the bodybuilder wants to happen. There is nothing worse than doing everything right to gain muscle only to find you weigh less after the bulking phase because you burned off muscle fibers while trying to build more muscle. Ultimate Nutrition ISO Mass prevents the body from using protein stores for energy.

Ultimate Nutrition ISO Mass is more than a basic weight gainer. Weight gainers typically have just protein and carbohydrates, but this supplement offers much more. Creatine, branched chain amino acids, enzymes and omega fatty acids are added to the basic protein/carbohydrate combination. The super weight gainer supports overall muscle and body health while preventing the breakdown of muscle fibers with 900 calories per serving.

Ultimate Nutrition ISO Mass is a gainer supplement for bodybuilders. Though many of the complexes promote overall health, the huge caloric load will not promote weight loss. This formula also contains creatine, known to cause water retention and weight gain. This is fine for the bodybuilder, but not for the dieter trying to lose weight. Dieters want to stay away from supplements with the word “mass” or “gainer” in the title. These are exclusively for bodybuilders.
