17α-Hydroxyprogesterone (17α-OHP), also known as 17-OH progesterone (17-OHP), or hydroxyprogesterone (OHP), is an endogenous progestogen steroid hormone related to progesterone. It is also a chemical intermediate in the biosynthesis of many other endogenous steroids, including androgens, estrogens, glucocorticoids, and mineralocorticoids, as well as neurosteroids.
Prednimustine, sold under the brand names Mostarina and Sterecyst, is a medication which is used in chemotherapy in the treatment of leukemias and lymphomas. It is the ester formed from two other drugs, prednisolone and chlorambucil. Rarely, it has been associated with myoclonus.
Clocortolone pivalate, also known as clocortolone trimethylacetate, is a synthetic glucocorticoid corticosteroid and corticosteroid ester which is marketed in the United States and Austria. It is the C21 pivalate (trimethylacetate) ester of clocortolone, and acts as a prodrug of clocortolone in the body.
Formebolone, also known (confusingly) as formyldienolone, as well as 2-formyl-11α-hydroxy-17α-methyl-δ1-testosterone, is an orally active anabolic-androgenic steroid (AAS) described as an anticatabolic and anabolic drug that is or has been marketed in Spain and Italy. As an AAS, it shows some anabolic activity, though it is inferior to testosterone in terms of potency, but is said to have virtually no androgenic activity. Formebolone counteracts the catabolic effects of potent glucocorticoids like dexamethasone phosphate. A close analogue, roxibolone, shows similar antiglucocorticoid activity to formebolone but, in contrast, is devoid of activity as an AAS.

Testosterone phenylpropionate, or testosterone phenpropionate, also known as testosterone hydrocinnamate, is a synthetic anabolic-androgenic steroid (AAS) and an androgen ester – specifically, the C17β phenylpropionate ester of testosterone – which was formerly marketed in Romania. It was first synthesized in 1951 and was first described in the literature by 1953. The medication was an ingredient of several isolated AAS commercial products, but was never widely used. Testosterone phenylpropionate was also notably a component of Sustanon and Omnadren, as well as of Estandron Prolongatum, Lynandron Prolongatum, and Mixogen.
Testosterone decanoate (BAN) is an androgen and anabolic steroid and a testosterone ester. It is a component of Sustanon, along with testosterone propionate, testosterone phenylpropionate, and testosterone isocaproate. The medication has not been marketed as a single-drug preparation. Testosterone decanoate has been investigated as a potential long-acting injectable male contraceptive. It has a longer duration of action than testosterone enanthate, but its duration is not as prolonged as that of testosterone undecanoate.
Testosterone isocaproate, sold under the brand names Sustanon 100, Sustanon 250, and Omnadren 250, is an androgen and anabolic steroid medication and a testosterone ester which has been used as a component of mixed testosterone ester preparations.
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.
Estradiol butyrylacetate (EBA), sold under the brand names Follikosid and Klimanosid-R Depot, is an estrogen medication which is no longer marketed. It is an estrogen ester, specifically, an ester of estradiol. It is administered by intramuscular injection and a single 10 mg dose has been said to have a duration of action of 2 to 3 weeks. The excretion of EBA in women has been studied.
Estradiol pivalate, also known as estradiol trimethyl acetate (E2-TMA) and sold under the brand name Estrotate, is an estrogen medication and an estrogen ester; specifically, the C3 pivalic acid ester of estradiol. It was marketed as an oil solution for intramuscular injection in the 1940s and 1950s. A combination of estradiol pivalate (1 mg/mL) and progesterone (10 mg/mL) in oil solution for intramuscular injection was available in 1949.
Testosterone hexahydrobenzoate (THHB), or testosterone cyclohexanecarboxylate (TCHC), sold under the brand names Testormon Depot, Sterandryl Retard, Tardosterandryl, and Testosteron-Depot among others, is an androgen and anabolic steroid medication and a testosterone ester. It is used by intramuscular injection and is provided in the form of ampoules containing 100 mg THHB in oil solution. The medication is no longer marketed.
Testosterone isobutyrate, sold under the brand names Agovirin-Depot and Perandren M among others, is an androgen and anabolic steroid medication and a testosterone ester which is used for indications such as low testosterone levels in men and delayed puberty in boys. It is available only in the Czech Republic and Slovakia. The medication is administered by injection into muscle once every 1 to 2 weeks in males. Unlike most other testosterone esters, which are provided as oil solutions, testosterone isobutyrate is formulated as a microcrystalline aqueous suspension.
Testosterone nicotinate is an androgen and anabolic steroid medication made by esterifying nicotinic acid and testosterone It was formulated as a 50 mg/mL aqueous suspension provided in ampoules. The medication was manufactured and sold by Lannacher Heilmittel GmbH in Austria. It is no longer marketed.
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 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.
Prebediolone acetate, also known as 21-hydroxypregnenolone 21-acetate or 21-acetoxypregnenolone (A.O.P.), as well as 3β,21-dihydroxypregn-5-en-20-one 21-acetate, is a synthetic pregnane steroid which is described as a glucocorticoid and has been used in the treatment of rheumatoid arthritis. It is the C21 acetate ester of prebediolone (21-hydroxypregnenolone), the C21 hydroxylated derivative of pregnenolone. Prebediolone acetate has been known since at least 1950. The compound is also an intermediate in a synthesis of deoxycorticosterone acetate (21-acetoxyprogesterone).
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.
