| Hey there, Many people have been asking me about turkesterone, which is a type of hormone known as a phytoecdysteroid that’s produced by various plants and fungi to defend against plant-eating insects. It’s a matter of the moment because studies apparently show that turkesterone can do many things, including boosting muscle protein synthesis and muscle growth, enhancing physical performance, improving glucose sensitivity, appetite, and digestion, lowering cholesterol levels, and more. There's a catch, though: All of these claims are based on animal research, which is useful for beginning to understand how substances work, but which also can't be directly extrapolated to humans. Unfortunately, there's very little research on turkesterone's effects in humans, and in the case of ecdysteroids, there's a study often held up as definitive proof of their power that came from scientists at German Sport University Cologne. Its findings are highly dubious, however, and were challenged by a higher-quality study from the University of Mary Hardin Baylor that found several ecdysteroids had no effect on fat loss, muscle or strength gain, or hormone levels. So, while turkesterone and other ecdysteroids are interesting molecules, we know very little about how they work, especially in humans, and many of the exaggerated claims made by the people selling them aren't borne out by the evidence.
