A prohormone is a substance that the body converts into a hormone. It is often used to enhance muscle growth and athletic performance. Prohormones are typically taken as supplements and can lead to increased levels of hormones like testosterone, which may help improve strength and recovery. These compounds are different from anabolic steroids, as they are precursors that require conversion in the body. While some athletes use prohormones for their potential benefits, they can also carry risks and side effects, similar to those associated with anabolic steroids. It's important to consult a healthcare professional before using them.
