The benefits of Serious Mass

Promotes rapid weight gain

Gainers provide a significant caloric surplus, ideal for those who have difficulty gaining weight, especially 'ectomorphs'.

High protein intake

Serious Mass contains 25g of protein per dose, which stimulates muscle synthesis.

Increases calorie intake without forcing you to eat

Useful for those who don't have much of an appetite but need to consume 3,000 to 4,000 calories a day.

Less nauseating than solid food

When your stomach is full, drinking a gainer is often easier than eating a big meal.

All about Serious Mass

What is a gainer?

A gainer is a calorie-rich dietary supplement combining mainly carbohydrates and proteins. It is designed to help people who have difficulty gaining weight or increasing muscle mass.

Why use a gainer?

Gainers make it easy to increase your daily calorie intake, essential for promoting mass gain. They are particularly suited to people with fast metabolisms or those who have difficulty consuming sufficient calories through diet alone.

More about Serious Mass

Description

image item

ON's Serious MASS is a formula designed primarily to build muscle mass.

Ideal for people who have difficulty gaining weight, Serious Mass helps to increase volume and develop the physique.

To gain mass and weight, you need to consume enough calories.

Sometimes it's difficult to properly ingest the increased nutritional intake needed to build muscle tissue and gain weight.

That's why Serious Mass was developed.

In fact, for people with a fast metabolism and who are very active during the day, it's virtually impossible to get the right nutrients in sufficient quantities on a daily basis through a conventional diet.

Thanks to its high-calorie formula with high protein and carbohydrate content plus the addition of a complete profile of vitamins, minerals and certain nutrients essential for muscle growth.

Serious Mass meets these needs. Each preparation contains 1,250 quality calories, providing over 50g of protein and 250g of carbohydrates.

To be enjoyed between meals, after training or simply as a meal replacement, Serious Mass is the ideal companion for those with ambitions in the weight room.

Swiss excellence for your fitness


Founded in 1999 by Pascal Guzzo, a sports, physiotherapy and nutrition enthusiast, STS was born of a simple conviction: better eating habits lead to better performance and better health.


As a physiotherapist and trainer of top-level athletes, Pascal quickly realized that even athletes often lack appropriate nutrition.

He then decided to offer them quality supplements, such as protein powder. Success was immediate! STS was born, and even obtained exclusive authorization to sell Whey Gold Standard in Switzerland, a first at the time.


Since then, STS has established itself as a key player in Switzerland, renowned for its irreproachable products, all manufactured in Europe or the UK and selected with the highest standards.

Guided by a strong ethic and the desire to help everyone regain their shape and vitality, the company now distributes to over 3,000 points of sale and continues to develop formulas perfectly adapted to the needs of the Swiss market.
