Boldenone (developmental code name RU-18761), is a naturally occurring anabolic–androgenic steroid (AAS) and the 1(2)-dehydrogenated analogue of testosterone.[3][4][5][6][7] Boldenone itself has never been marketed; as a pharmaceutical drug, it is used as boldenone undecylenate, the undecylenate ester.[3][4][7]

Pharmacology
Pharmacodynamics
Like other AAS, boldenone is an agonist of the androgen receptor (AR).[7] The activity of boldenone is mainly anabolic, with a low androgenic potency. Boldenone will increase nitrogen retention, protein synthesis, increases appetite and stimulates the release of erythropoietin in the kidneys.[8]
Chemistry
Boldenone, also known as Δ1-testosterone, 1-dehydrotestosterone, or androsta-1,4-dien-17β-ol-3-one, is a naturally occurring androstane steroid and a derivative of testosterone.[3][4][7] It is specifically testosterone with a double bond between the C1 and C2 positions.[3][4][7] A related compound is quinbolone, the 17-cyclopentenyl enol ether of boldenone.[3][4]
Sources
Boldenone occurs naturally in the scent gland of Ilybius fenestratus, a species of aquatic beetle.[3]
History
Ciba reportedly patented boldenone in 1949.[7] It subsequently developed several experimental esters of the drug in the 1950s and 1960s.[7] One of these was boldenone undecylenate, which was introduced for clinical use under the brand name Parenabol and saw some use in the late 1960s and early 1970s.[7] However, it was discontinued before the end of the 1970s.[7] Subsequently, boldenone undecylenate was introduced by Squibb under the brand name Equipose for veterinary use, most commonly in horses.[7]
Society and culture
Generic names
Boldenone is the generic name of the drug and its INN and BAN.[3][4][5][6]
Brand names
Boldenone is marketed as veterinary drug as boldenone undecylenate (a derivative of boldenone) under the following brand names: Boldebal H, Equipoise, and Sybolin.[6] It is marketed as a veterinary combination drug with methandriol under the brand name Drive.[6]
In Ukraine, it is marketed for human consumption as the injectable steroid Boldenol.[9]
Doping in sports
There are many known cases of doping in sports with boldenone undecylenate by professional athletes.
