Synthetic hormones derived from testosterone that promote muscle and bone growth (anabolic effect) and masculine characteristics (androgenic effect). Prescription medicines in most countries and controlled substances in many.
The term covers testosterone itself, its injectable esters, oral 17-alpha-alkylated compounds and structurally modified derivatives. All act through the androgen receptor, which is why anabolic and androgenic effects cannot be fully separated. Not to be confused with corticosteroids, the anti-inflammatory steroids used in asthma inhalers and skin creams.
