[ 15][ 4][ 6] It was given at a dosage of 5 to 10 mg/day in men and 2.5 mg/day in women. [ 16][ 17][ 1] v. t.
Chemistry. Nandrolone phenylpropionate, or nandrolone 17β-phenylpropionate, is a synthetic estrane steroid and a derivative of testosterone. [ 8][ 9] It is an androgen ester; specifically, it is the C17β phenylpropionate ester of nandrolone (19-nortestosterone), which itself is the 19- demethylated analogue of testosterone. [ 8][ 9] v. t. e.
Trenbolone acetate was discovered in 1963 and was introduced for veterinary use in the early 1970s. [ 5][ 10][ 11] In addition to its veterinary use, trenbolone acetate is used to improve physique and performance, and is purchased from black market suppliers. [ 5] The drug is a controlled substance in many countries and so non-veterinary use is ...
Anabolic steroids, also known as anabolic-androgenic steroids (AAS), are a class of drugs that are structurally related to testosterone, the main male sex hormone, and produce effects by binding to the androgen receptor (AR). Anabolic steroids have a number of medical uses, [ 1] but are also used by athletes to increase muscle size, strength ...
Nandrolone is an agonist of the AR, the biological target of androgens like testosterone and DHT. Unlike testosterone and certain other anabolic steroids, nandrolone is not potentiated in androgenic tissues like the scalp, skin, and prostate, hence deleterious effects in these tissues are lessened. [ 22]
Side effects of boldenone undecylenate include symptoms of masculinization like acne, increased hair growth, voice changes, and increased sexual desire. [6] The drug is a synthetic androgen and anabolic steroid and hence is an agonist of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT).
Doping in sport. The government of the German Democratic Republic (GDR) conducted a decades-long program of coercive administration and distribution of performance-enhancing drugs, initially testosterone, later mainly anabolic drugs, to its elite athletes. The aim of the program, which began in the 1960s, was to bolster East Germany's state ...
Side effects of nandrolone decanoate may include symptoms of masculinization like acne, increased hair growth, and voice changes. [3] The medication is a synthetic androgen and anabolic steroid and hence is an agonist of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT).
