Cordyceps is a bioactive mushroom, taking about six years to complete its life cycle, from which natural Cordyceps Sinensis is created. Consequently, the natural product is extremely rare and incredibly expensive. Due to the scarcity and high price of natural Cordyceps, scientists have developed a variety of mycelial products to be used as a substitute.

Our mushroom extract takes all of the active ingredients in the mushroom, using our latest technology to get the most concentrated benefits, meaning you can get the same effect for a much smaller price. Reflex Nutrition obtain this highly sought after Cs-4 extract direct from China and immediately encapsulate it without any heat or additives to preserve its freshness and strength.
