What is Thermo Fusion®?

Thermo Fusion® is a diet supplement designed specifically to support weight management goals, with the correct doses of the highest quality ingredients.

James Phillips, Managing Director, explains;

“When we formulated Thermo Fusion® we did so with one aim, to provide consumers with something that really delivers. That’s only really possible when you use the right ingredients in meaningful doses. That’s exactly what we deliver and we guarantee it.

Most competitor products will try and deliver using one or two capsules per dose, I’m afraid to say that type of approach is very limiting to the consumer and ignorant on behalf of the formulator.”

Who is it for?

Thermo Fusion® is the perfect diet aid for men and women wanting that extra boost whilst dieting and exercising. First and foremost, Thermo Fusion® is absolutely unique, it has been designed with a single aim – to outperform every other product in the category.

Not for use by individuals under the age of 18. Do not use if you are pregnant or lactating, or if you suffer from high blood pressure.

What are the benefits?

    (verified owner):

    I consistently train and keep a well balanced diet all year round. However when I want to accelerate fat loss for a photo shoot or physique competition, Reflex Thermo Fusion is an invaluable supplement to achieving the more lean look.
    It contains the perfect mix and balance of ingredients that speed up thermogenesis in my body to burn extra calories whilst maintaining my energy levels.
    The high caffeine levels found in the competition are significantly replaced by green tea which also provide an impressive list of health benefits too. A win win product!
