4-Hydroxytestosterone (4-OHT or 4,17beta-dihydroxy-4-androstene-3-one) is an anabolic steroid. It was first patented by G.D. Searle & Company in 1955 and is testosterone with a hydroxy group at the four position. 4-OHT has moderate anabolic, mild androgenic, and anti-aromatic properties and is similar to the steroid clostebol.

4-Hydroxytestosterone  is a legal steroidal compound that is relatively new to the market. Unlike prohormones, 4-OHT does not require enzymatic conversion to have an anabolic effect. It was first patented by G.D. Searle & Co. in 1955, but it did not reach the commercial market, and has recently become available as a dietary supplement. Chemically, 4-OHT is testosterone with a hydroxy group at the four position, making it most similar to the steroid clostebol, which has a chloro group at the four position. These two compounds are also very similar in effect.
