DHEA is the most abundant adrenal steroid hormone found in the body. This vital hormone is the metabolic precursor to testosterone and may support muscle growth, cellular energy formation, and fat metabolism. DHEA has been shown to combat the catabolic effects that cortisol have on muscle mass. Because of this, it may have a profound influence on positive body composition supporting the growth of lean muscle tissue. Many bodybuilders use DHEA to ensure their bodies have the raw ingredients needed to produce sufficient testosterone, the muscle-building hormone.
