In bodybuilding are often used synthetic testosterone drugs.
Testosterone itself biologically inactive and weakly binds to the androgen receptor (is actually a prohormone), and before the act on the androgen receptors of the target cell, it should be subject to modification by the enzyme 5α-reductase. This forms the biologically active form of testosterone - dihydrotestosterone.
