Ecdysterone is a substance that in the world of bodybuilding passes without much of echo. In reality, however, it is strongly correlated with anabolic hormones and shows a great potential. As it turns out that regular supplementation in appropriate doses can contribute to an increase in lean body mass, increase of muscle strength and endurance, as well as acceleration of metabolism. Ecdysterone significantly improves protein synthesis, characterized by anti-catabolic properties and blocking too high estrogen levels. It is also expected that it may increase erythropoiesis.
