Dihydrotestosterone undecanoate (DHTU), also known as androstanolone undecanoate or stanolone undecanoate, is a synthetic androgen and anabolic steroid (AAS) which was never marketed.[2][1][3][4] It is an androgen ester; specifically, it is the C17β undecanoate (undecylate) ester of dihydrotestosterone (DHT).[2][1][3][4][5] DHTU is a prodrug of DHT.[2][5][4] Similarly to testosterone undecanoate (TU), DHTU is orally active.[1][3][4] It occurs as an important active metabolite of oral TU.[6][2][5][7][8] The 5α-reductase inhibitor finasteride in combination with oral TU has no effect on the first-pass transformation of TU into DHTU or DHT, probably because of its unique lymphatic route of absorption.[9] Oral DHTU may be absorbed by the lymphatic system similarly to TU, and this may explain its oral bioavailability.[2][1][3][4]
