Ecdysteroids are a family of steroid hormones found primarily in insects and some plants. They've gained popularity in the fitness community for their potential muscle-building properties without the side effects of traditional anabolic steroids.
What Are Ecdysteroids?
Ecdysteroids are naturally occurring compounds that regulate molting and development in insects. In humans, they're believed to interact with estrogen receptors and may support protein synthesis and muscle growth.
Types of Ecdysteroids
The most popular ecdysteroids used in supplements include:
Turkesterone
The most popular ecdysteroid. Known for potential muscle-building effects.
