[2] [3] [6] It is the C17β undecylenate (undecenoate) ester of boldenone (δ 1-testosterone, 1-dehydrotestosterone, or androsta-1,4-dien-17β-ol-3-one), which itself is the C1(2) dehydrogenated analogue of testosterone and a naturally occurring androgen found in the scent gland of Ilybius fenestratus (a species of aquatic beetle).
Equine estrogens, or horse estrogens, are estrogens found in horses. [1] [2] [3] ... Testosterone: T; 4-Androstenolone <0.0001–<0.01 <0.002–0.040 >5000 >5000 ...
In the 20th century, testosterone was isolated and characterized by scientists. [55] In 1941, the first record of synthesized testosterone use occurred when a horse was given testosterone which successfully improved its race performance. [56] Sports trainers soon after began advocating for testosterone use. [55]
Boldenone, also known as Δ 1-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.
Stallions follow the conformation and phenotype of their breed, but within that standard, the presence of hormones such as testosterone may give stallions a thicker, "cresty" neck, as well as a somewhat more muscular physique as compared to female horses, known as mares, and castrated males, called geldings.
Altrenogest, also known as 17α-allyl-19-nor-δ 9,11-testosterone or as 17α-allylestra-4,9,11-trien-17β-ol-3-one, is a synthetic estrane steroid and derivative of 19-nortestosterone and 17α-allyltestosterone, or of 17α-allyl-19-nortestosterone.
A few horse owners delay gelding a horse on the grounds that the testosterone gained from being allowed to reach sexual maturity will make him larger. However, recent studies have shown that this is not so: any apparent muscle mass gained solely from the presence of hormones will be lost over time after the horse is gelded, and in the meantime ...
Trenbolone, also known as 19-nor-δ 9,11-testosterone or as estra-4,9,11-trien-17β-ol-3-one, is a synthetic estrane steroid and a derivative of nandrolone (19-nortestosterone). [ 2 ] [ 3 ] [ 6 ] It is specifically nandrolone with two additional double bonds in the steroid nucleus.
