Androstanolone benzoate, also known as stanolone benzoate or dihydrotestosterone benzoate (DHTB), as well as 5α-androstan-17β-ol-3-one 17β-benzoate, is a synthetic androgen and anabolic steroid and a dihydrotestosterone ester. It is used as an injectable and acts as a prodrug of androstanolone.

Androstanolone enanthate, also known as stanolone enanthate or dihydrotestosterone heptanoate (DHTH), as well as 5α-androstan-17β-ol-3-one 17β-heptanoate, is a synthetic androgen and anabolic steroid and a dihydrotestosterone ester. It is used as an injectable and acts as a prodrug of androstanolone. The drug has been studied in and found to be effective in the treatment of gynecomastia in boys and adult men. The pharmacology of androstanolone enanthate has been studied.

Androstanolone propionate, also known as stanolone propionate or dihydrotestosterone propionate (DHTP), as well as 5α-androstan-17β-ol-3-one 17β-propionate, is a synthetic androgen and anabolic steroid and a dihydrotestosterone ester that is marketed in Italy. It is used as an injectable and acts as a prodrug of androstanolone.

Androstanolone valerate, also known as stanolone valerate or dihydrotestosterone pentanoate, as well as 5α-androstan-17β-3-one 17β-valerate, is a synthetic androgen and anabolic steroid and a dihydrotestosterone ester. It is used as an injectable and acts as a prodrug of androstanolone.

Dihydrotestosterone acetate, also known as androstanolone acetate or stanolone acetate, as well as 5α-dihydrotestosterone 17β-acetate, is a synthetic androgen and anabolic steroid and a dihydrotestosterone ester that was never marketed.

Dihydrotestosterone butyrate, also known as androstanolone butyrate or stanolone butyrate, as well as 5α-dihydrotestosterone 17β-butanoate, is a synthetic androgen and anabolic steroid and a dihydrotestosterone ester that was never marketed.

Dihydrotestosterone formate, also known as androstanolone formate or stanolone formate, as well as 5α-dihydrotestosterone 17β-formate, is a synthetic androgen and anabolic steroid and a dihydrotestosterone ester that was never marketed.

Dihydrotestosterone undecanoate (DHTU), also known as androstanolone undecanoate or stanolone undecanoate, is a synthetic androgen and anabolic steroid (AAS) which was never marketed. It is an androgen ester; specifically, it is the C17β undecanoate (undecylate) ester of dihydrotestosterone (DHT). DHTU is a prodrug of DHT. Similarly to testosterone undecanoate (TU), DHTU is orally active. It occurs as an important active metabolite of oral TU. 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. Oral DHTU may be absorbed by the lymphatic system similarly to TU, and this may explain its oral bioavailability.

Testifenon, also known as testiphenon, testiphenone, chlorphenacyl dihydrotestosterone ester, or dihydrotestosterone 17β-(4- phenyl)acetate, is a synthetic anabolic–androgenic steroid (AAS) and a cytostatic antineoplastic agent that was never marketed. It is an androgen ester – specifically, a chlorphenacyl nitrogen mustard ester of dihydrotestosterone (DHT) – and acts as a prodrug of these two components in the body. The drug was developed in Russia as a tissue-selective cytostatic drug for the treatment of various cancers occurring in androgen receptor-expressing tissues that would have reduced side effects and toxicity relative to other chemotherapy drugs.
