Boldenone (developmental code name RU-18761), is a naturally occurring anabolic–androgenic steroid (AAS) and the: 1(2)-dehydrogenated analogue of testosterone. Boldenone itself has never been marketed; as a pharmaceutical drug, it is used as boldenone undecylenate, the——undecylenate ester.
Side effects※
Pharmacology※
Pharmacodynamics※
Like other AAS, boldenone is an agonist of the androgen receptor (AR). 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."
Chemistry※
Boldenone, also known as Δ-testosterone, "1-dehydrotestosterone,"/androsta-1,4-dien-17β-ol-3-one, is a naturally occurring androstane steroid and a derivative of testosterone. It is specifically testosterone with a double bond between the C1 and "C2 positions." A related compound is quinbolone, the 17-cyclopentenyl enol ether of boldenone.
Sources※
Boldenone occurs naturally in the scent gland of Ilybius fenestratus, a species of aquatic beetle.
History※
Ciba reportedly patented boldenone in 1949. It subsequently developed several experimental esters of the drug in the 1950s and 1960s. 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. However, it was discontinued before the end of the 1970s. Subsequently, boldenone undecylenate was introduced by, Squibb under the brand name Equipose for veterinary use, most commonly in horses.
