Nandrolone, also known as 19-nortestosterone, is an endogenous androgen which exists in the male body at a ratio of 1:50 compared to testosterone. It is also an anabolic steroid (AAS) which is medically used in the form of esters such as nandrolone decanoate and nandrolone phenylpropionate. Nandrolone esters are used in the treatment of anemias, cachexia, osteoporosis, breast cancer, and for other indications. They are now used by oral administration or instead are given by injection into muscle or fat.
Trenbolone is an androgen and anabolic steroid (AAS) of the nandrolone group which itself was never marketed. Trenbolone ester prodrugs, including trenbolone acetate and trenbolone hexahydrobenzylcarbonate, are or have been marketed for veterinary and clinical use. Trenbolone acetate is used in veterinary medicine in livestock to increase muscle growth and appetite, while trenbolone hexahydrobenzylcarbonate was formerly used clinically in humans but is now no longer marketed. In addition, although it is not approved for clinical or veterinary use, trenbolone enanthate is sometimes sold on the black market under the nickname Trenabol.
Oxabolone cipionate, or oxabolone cypionate, also known as 4-hydroxy-19-nortestosterone 17β-cypionate or estr-4-en-4,17β-diol-3-one 17β-cypionate, is synthetic and injected anabolic–androgenic steroid (AAS) and derivative of nandrolone (19-nortestosterone) which has been marketed in Europe. It is the C17β cypionate ester and a prodrug of oxabolone (4-hydroxy-19-nortestosterone).
Bolandiol is an anabolic-androgenic steroid (AAS) that was never marketed. However, a dipropionate ester derivative, bolandiol dipropionate, has been marketed. Bolandiol and its dipropionate ester are unique among AASs in that they reportedly also possesses estrogenic and progestogenic activity.
Hydroxyprogesterone heptanoate (OHPH), also known as hydroxyprogesterone enanthate (OHPE) and sold under the brand names H.O.P., Lutogil A.P., and Lutogyl A.P. among others, is a progestin medication used for progestogenic indications. It has been formulated both alone and in together with estrogens, androgens/anabolic steroids, and other progestogens in several combination preparations. OHPH is given by injection into muscle at regular intervals.

Nandrolone cypionate, or nandrolone cipionate, also known as 19-nortestosterone 17β-cyclopentanepropionate, is a synthetic androgen and anabolic steroid and a nandrolone ester.
Nandrolone cyclohexylpropionate, or nandrolone cyclohexanepropionate, also known as 19-nortestosterone 17β-(3-cyclohexyl)propionate (NTHCP), is a synthetic androgen and anabolic steroid and a nandrolone ester that is or has been marketed in Spain, Austria, and Israel.
Nandrolone cyclotate, or nandrolone ciclotate, also known as 19-nortestosterone 17β-ciclotate, is a synthetic and injected anabolic–androgenic steroid (AAS) of the nandrolone (19-nortestosterone) group which was never marketed. It is an androgen ester – specifically, the C17β ciclotate (4-methylbicyclo[2.2.2]oct-2-ene-1-carboxylate) ester of nandrolone. Nandrolone cyclotate has potent and prolonged activity as an AAS when administered by intramuscular injection and is reported to have a similar duration of action to that of nandrolone decanoate via this route.
Nandrolone furylpropionate (NFP), also known as 19-nortestosterone 17β-(2-furanyl)propanoate, is a synthetic androgen and anabolic steroid and a nandrolone ester. It was developed and marketed by Mochida Pharmaceutical in Japan in the 1960s.
Nandrolone hexyloxyphenylpropionate, also known as 19-nortestosterone 17β-(3- phenyl)propionate, is a synthetic androgen and anabolic steroid and a nandrolone ester that is marketed in France, Denmark, Austria, Luxembourg, and Turkey. It has been studied as a potential long-acting injectable male contraceptive, though it has not been marketed for this indication. Approximately 70% of men became azoospermic, while the remaining men all became oligospermic. NHPP has a mean residence time in the body of 29.1 days and an elimination half-life in the body of 20.1 days.
Nandrolone hydrogen succinate, or nandrolone hemisuccinate, also known as 19-nortestosterone 17β-(3-carboxy)propionate, is a synthetic androgen and anabolic steroid and a nandrolone ester that is or has been marketed in Italy.
Nandrolone laurate, or nandrolone dodecanoate, also known as 19-nortestosterone 17β-laurate, is a synthetic androgen and anabolic steroid and a nandrolone ester. It is used in veterinary medicine in Austria, France, the Netherlands, and Switzerland.
Nandrolone phenylpropionate (NPP), or nandrolone phenpropionate, sold under the brand name Durabolin among others, is an androgen and anabolic steroid (AAS) medication which has been used primarily in the treatment of breast cancer and osteoporosis in women. It is given by injection into muscle once every week. Although it was widely used in the past, the drug has mostly been discontinued and hence is now mostly no longer available.
Nandrolone propionate, or nandrolone propanoate, also known as 19-nortestosterone 17β-propionate, is a synthetic androgen and anabolic steroid and nandrolone ester that is or has been marketed in Spain.
Nandrolone sulfate, also known as 19-nortestosterone 17β-sulfate and used medically as the sodium salt nandrolone sodium sulfate, is a synthetic androgen and anabolic steroid and a nandrolone ester which is or has been used as an ophthalmic drug in the form of eye drops in Spain, Denmark, Switzerland, France, Portugal, and Belgium.
Nandrolone undecanoate (NU), also known as nandrolone undecylate, and sold under the brand names Dynabolon, Dynabolin, and Psychobolan, is an androgen and anabolic steroid medication and a nandrolone ester. It was developed in the 1960s, and was previously marketed in France, Germany, Italy, and Monaco, but has since been discontinued and is now no longer known to be available. The pharmacokinetics of nandrolone undecanoate alone (Dynabolon) and in combination with other steroid esters (Trophobolene) have been studied and compared.
Bolandiol dipropionate (USAN), or bolandiol propionate (JAN), also known as norpropandrolate or 19-nor-4-androstenediol dipropionate, as well as estr-4-ene-3β,17β-diol 3,17-dipropionate, is a synthetic anabolic-androgenic steroid (AAS) and derivative of 19-nortestosterone (nandrolone). It is an androgen ester – specifically, the 3,17-dipropionate ester of bolandiol (19-nor-4-androstenediol).
Androstenediol dipropionate, or 5-androstenediol 3β,17β-dipropionate, also known as androst-5-ene-3β,17β-diol 3β,17β-dipropionate, is a synthetic anabolic–androgenic steroid and an androgen ester – specifically, the dipropionate diester of 5-androstenediol (androst-5-ene-3β,17β-diol) – which has been marketed in Europe, including in Spain, Italy, and Austria.
