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.
