Serious Mass - all-in-one blend that is a source of protein and contains a high dose of carbohydrates, which will help to significantly increase energy intake
Serious Mass is a packed gainer that will help effectively increase energy intake, for example, during the bulking phase when it can be challenging to consume enough calories. The base of the mixture is a good dose of quality carbohydrates. In addition, thanks to the whey concentrate, the gainer is also a source of proteins that contribute to the growth and maintenance of muscle mass, as well as to maintaining healthy bones. But the ingredients also include creatine and a variety of vitamins and minerals to help with overall health and vitality.
It contains vitamin B1 (thiamine), which supports proper heart function. It also contributes to normal energy metabolism. Vitamins B2 (riboflavin) and B3 (niacin), in turn, contribute to the normal functioning of the nervous system. Vitamins B6 (pyridoxine), B7 (biotin) and B9 (folic acid), in turn, play a role in maintaining proper mental function. However, not to be missed is vitamin B12 (cobalamin), which contributes to the reduction of both fatigue and exhaustion. In the composition, you will also find vitamin C (ascorbic acid), which supports the proper function of the immune system. In addition, it also contributes to the optimal production of collagen for the proper function of bones, cartilage, blood vessels and skin. However, we can't forget vitamin E, which contributes to the protection of cells from oxidative stress.
Minerals also contribute to optimal body function. Magnesium, for example, supports proper muscle and bone function. Zinc, in turn, contributes to normal cognitive functions. In addition, it supports the maintenance of normal testosterone levels in the blood. Iron also plays an important role, which contributes to the normal production of red blood cells and haemoglobin and supports oxygen transport in the body. Creatine also plays a role, helping to boost performance during short intervals of intense training.
As you can see, Serious Mass is packed with not only macronutrients but also micronutrients to help with overall body care. Plus, it will win you over with its great taste and quick preparation, making it an ideal addition to the pack of all strength athletes and fitness enthusiasts. Enjoy this gainer between meals, after training or before bedtime.

I opened the product, and the taste is not very good, especially because of the vanilla flavour. When mixed with water, it feels like I am drinking sugar water. I will never order from these websites again and, if possible, I would like a refund with other products, at least banana-flavoured ones.Was this review helpful to you?- Verified purchase

Serious Mass - Optimum Nutrition is a high-calorie supplement designed to increase your total energy intake. While it can be consumed on non-training days, its protein content is specifically included to contribute to the growth and maintenance of muscle mass, which is stimulated by exercise. Consuming a significant calorie surplus without corresponding physical activity may lead to an increase in body fat rather than muscle.
Optimum Nutrition Serious Mass is a comprehensive gainer formulated to support significant mass and weight gain, delivering over 1,260 kcal per serving from a blend rich in carbohydrates. While it includes whey protein to contribute to muscle growth, its primary purpose is to create a substantial calorie surplus for bulking. A typical whey protein supplement, by contrast, is a concentrated protein source with far fewer calories, carbohydrates, and fats, and is generally used to increase protein intake for muscle maintenance without significantly impacting overall calorie consumption.
