Want to lose weight, keep your lean muscle and be race ready? While diet and exercise are the best ways to get there, everyone could a little extra help from a supplement like ThermoLean®.
Since 1997 Bio-Synergy has been setting standards in sports nutrition. Certified B Corporation®. Made in the UK. Independently tested. Used by elite and professional athletes for over 25 years.
Activeman Thermo Lean® is a high performance fat burner, engineered by Bio-Synergy and James Cracknell to help you strip away body fat and reach your ideal racing weight. Thermo Lean® is the result of our relentless search for the world’s the most effective yet natural fat burning ingredients, backed by reliable scientific studies from reputable institutions. We picked the top 10 and combined them into one product. Our patented formula starts with green tea, green coffee and caffeine to boost your metabolism, enhancing your body’s ability to burn fat while giving you an energy surge. We also included high doses of calcium and copper, which contribute to energy yielding metabolism, meaning they help your body turn fat into energy. Zinc and alpha lipoic acid are also included as they contribute to protein, carbohydrate and fat metabolism, ensuring these macronutrients from food are used for energy and don’t become body fat. You also get a dose of chromium, which supports the maintenance of normal blood glucose levels, and can curb your sugar cravings. As you can see, Thermo Lean is packed full of micronutrients that are designed to burn fat, boost your energy levels and power you to a PB performance.
