Details

Mega Mass is a comprehensive gainer with a high content of protein, vitamins, minerals, and creatine, designed for anyone looking to increase their caloric intake

Mega Mass is a complex blend, rich in carbohydrates and protein, ideal for those aiming to increase their caloric intake. The carbohydrate content includes maltodextrin, known for its fast absorption. The formula is also packed with protein, which supports muscle growth, maintenance, and bone health. The proteins are primarily sourced from milk protein isolate, whey protein concentrate, and dried egg albumin. Thanks to these ingredients, the gainer’s energy value can significantly increase caloric intake, with one serving containing at least 540 kcal, depending on the flavour.

 

If mixed with 550 ml of semi-skimmed milk (1.5% fat) instead of water, the caloric value can exceed 800 kcal. Additionally, the formula includes a functional dose of vitamins and minerals, with vitamin C being particularly noteworthy. Vitamin C contributes to maintaining the proper functioning of the immune system, supports the reduction of fatigue, and, along with thiamine, has an effect on the nervous system. Next, zinc contributes to proper protein synthesis and maintaining normal testosterone levels in the blood.

 

The effectiveness of this gainer is further enhanced by the inclusion of creatine monohydrate, which increases performance during short, consecutive intervals of intense training, provided a daily intake of 3 g is met—something easily achieved with Mega Mass. Overall, Mega Mass is an excellent choice for ectomorphs, hardgainers, and anyone looking to increase their caloric intake and build muscle mass. A nice bonus is its delicious taste and creamy consistency, making it enjoyable post-workout or any time of the day.

I have a vanilla flavor, and it tastes almost not at all; rather, it tastes like sweetened starch. It is not repulsive, but I cannot enjoy it due to the taste. Regarding the results, I cannot assess

    From this gainer, combined with creatine, I have gained mass impressively. In two months, 15 kg up. Of course, with proper nutrition as well. Super for building volume.
