This formula combines four carefully selected ingredients for their complementary action on men’s tone and vitality: tribulus terrestris, maca, Shoden ashwagandha and Ultimine zinc. Together they provide broad support for energy metabolism, muscle function and natural hormonal balance, with each ingredient chosen for purity, concentration and optimal bioavailability, in the Nutrimuscle quality tradition.

Tribulus terrestris is an adaptogenic plant used for centuries in Ayurveda and traditional Chinese medicine to support male vitality. Rich in steroidal saponins, notably protodioscin, tribulus is traditionally associated with maintaining tone, energy and general wellbeing, and is particularly popular with athletes and active men.

Maca (Lepidium meyenii) is a root grown above 4,000 metres in the Peruvian Andes. Considered an adaptogenic superfood, it is traditionally used to support energy, physical endurance and overall wellbeing, and is particularly known for its action on stress resistance and its content of essential minerals such as calcium, iron, potassium and zinc.

Ashwagandha (Withania somnifera) is one of the most iconic plants in Ayurvedic medicine. Nutrimuscle selected the Shoden extract, standardised to 35% withanolides — the highest concentration available on the market. This patented quality ensures optimal effectiveness in supporting hormonal balance, stress resistance and sleep quality, and is also known to support physical and mental performance.

Zinc is a crucial trace element for many bodily functions: carbohydrate and protein metabolism, immune function, fertility, and DNA synthesis. Nutrimuscle uses the Ultimine form, a highly bioavailable zinc complex. Zinc contributes to the maintenance of normal testosterone levels in the blood, to normal acid-base metabolism, and to normal cognitive function, and plays a key role in fertility and reproduction.

The recommended dose is 4 capsules per day, spread across meals for optimal absorption of the actives. The 120-capsule bottle covers a full one-month course. Because of its zinc content, it’s recommended to limit use to a course of a few weeks to a few months rather than continuous long-term use. For best results, combine the Testosterone Booster with a balanced diet, regular physical activity and good-quality sleep.

Not recommended for children, teenagers, or pregnant or breastfeeding women. People with hyperthyroidism or haemochromatosis should consult a healthcare professional before use. Not recommended alongside treatment for high blood pressure or diabetes. Do not exceed the recommended daily dose. Store in a cool, dry place away from light and out of reach of children.

Is the Testosterone Booster a doping substance?

No, it’s a food supplement made from natural ingredients (adaptogenic plants and minerals) containing no substance on any prohibited list. Actives such as tribulus, maca, ashwagandha and zinc are permitted in competition.

When should I take the 4 capsules during the day?

It’s best to spread the 4 capsules across meals — for example 2 in the morning and 2 at lunch, or 1 at each meal (breakfast, lunch, snack, dinner). This optimises absorption and provides steady release through the day.

How long before I feel the effects?

First effects on tone and vitality are usually felt after 2-4 weeks of regular use. For best results, a full one-month course is recommended, extendable to 2-3 months depending on your needs, as part of an overall approach including diet, exercise and sleep.
