Instant Mass® Heavyweight - a blend of quality protein and carbohydrates with 1089 kcal per serving

Instant Mass® Heavyweight is a combination of quality proteins, carbohydrates, creatine, chelated minerals, and vitamins, which supply 1089 kcal in one serving. More precisely, the source of 60 g of protein is whey protein hydrolyzate, selective bioactive whey concentrate, natural whey isolate, which is known for its high BCAA content, and ultra filtered micellar casein. Due to the fact that it is a combination of quickly and slowly absorbed proteins, they will start to enter your body almost immediately. However, thanks to the last-mentioned type of protein, the body will be supplied for more than four hours


Quality sources were also used for the carbohydrate component. The base is a blend of "whole grain" oat carbohydrates and maltodextrin. This combination ensures the body's energy supply for a longer period of time without much fluctuation. In addition, Gainer also contains creatine, which increases physical performance during short-term consecutive sessions of very intense exercise. The minerals contained are in the form of a chelate thanks to which they are well absorbed by the body. It further contains magnesium, which contributes to the reduction of fatigue and exhaustion, the proper function of muscles, the maintenance of healthy bones, and normal protein synthesis. The zinc contained has an effect on the metabolism of carbohydrates, proper cognitive function, and maintaining normal testosterone levels in the blood. 


The gainer also contains a wide range of vitamins. Specifically, vitamin A, vitamin C, complete B complex, and vitamin D, which contribute to the proper function of muscles and the immune system. Thanks to the ingredients, it is a quality and complex gainer that can help you gain muscle mass.
