The Benefits of the 24-Hour Pack

Supports post-workout recovery

Isolate quickly provides 25 g of high-quality protein, rich in essential amino acids, to support the maintenance and growth of muscle mass after a workout.

Quickly delivers protein to the muscles

Because it is digested slowly, casein gradually releases its amino acids over several hours. It is ideal before bedtime or during a long period without a meal.

Ensures a sustained release of amino acids throughout the night

The combination of Isolate and Casein helps meet your protein needs both day and night: rapid absorption after exercise and sustained release during recovery.

Everything You Need to Know About Pack 24h

Why Should You Consume Casein?

Casein is a slow-digesting protein that gradually releases its amino acids over several hours. It is particularly well-suited for consumption before bedtime or during long periods without meals, to prolong protein intake and support muscle recovery overnight.

Why Take Isolate?

Isolate is a rapidly absorbed protein, ideal for consumption after a workout or throughout the day. High in protein and low in sugar and fat, it helps maintain and build muscle mass while making it easy to increase your daily protein intake.

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.

Frequently asked questions

What exactly is included in the 24H Pack?

The pack includes a 930-gram 100% Isolate Gold Standard (about 31 servings), a 924-gram 100% Casein Gold Standard (about 28 servings), and a free 600-ml Optimum shaker with compartments.

Why is it called the 24-Hour Pack?

Because it combines two complementary proteins. The Isolate is quickly absorbed and is mainly used after a workout, upon waking, or between meals. Casein is digested more slowly and is particularly suitable in the evening or before a long period without food intake.

When should you take Isolate and Casein?

Isolate can be consumed after a workout, upon waking up, or as a snack to supplement your daily protein intake. Casein is ideal before bedtime or between meals that are far apart, thanks to its slower release.

Why is this bundle cheaper than buying the items separately?

The bundle includes both protein powders and the shaker at a special price of 109 CHF instead of 148 CHF—a savings of 39 CHF. The shaker is included in the offer so you can easily prepare and carry your drinks.

How long do the products in the pack last?

The Isolate container holds about 31 servings, and the Casein container holds about 28 servings. If you take one serving of each product per day, the pack will last approximately four weeks. It will last longer if you use them only based on your workouts and needs.

Is shipping free?

Yes, shipping is free in Switzerland on orders of 50 CHF or more. Since the 24-Hour Pack is priced at 109 CHF, shipping is free.
