Anabolic steroidAnabolic steroidsalso known more properly as anabolic—androgenic steroids AASandrogenic anabolic steroid hormones are steroidal androgens that include natural androgens like testosterone as well as synthetic androgens that are structurally related and have similar effects to testosterone. They are anabolic and increase protein within anwbolicespecially in skeletal musclesand androenic have varying degrees of androgenic and virilizing effects, including induction of the development and maintenance of masculine secondary sexual characteristics such as the growth of facial and body hair. Androgens or AAS are one of three types of sex hormone agoniststhe others being estrogens like estradiol and progestogens like progesterone. AAS were synthesized in c10 wiki s, and are now used therapeutically aanbolic medicine to stimulate androgenic anabolic steroid hormones growth and appetiteinduce male puberty and treat chronic androfenic conditions, such as cancer and AIDS. The American College of Sports Medicine acknowledges that AAS, in the presence of adequate diet, can contribute to increases in body weightoften as lean androgenic anabolic steroid hormones increases and that the gains in muscular strength achieved through high-intensity exercise and proper diet can be additionally increased by the use of AAS in some individuals.
Anabolic steroid - Wikipedia
Endocrine responses in seven power athletes were investigated during a 12 week strength training period, when the athletes were taking high doses of andro genic-anabolic steroids, and during the 13 weeks fol lowing drug withdrawal. In relation to the changes in the thyroid function param eters measured, we suggest that the primary target of androgen action was TBG biosynthesis.
In five of the seven subjects, serum concentrations of growth hor mone increased at some point of the study 5 to fold. Because of the use of exogenous testosterone, serum testosterone concentration tended to increase. This was characterized by a very low serum testosterone concentration 5. Cessation of drug use resulted in return of all the variables measured to the initial values, except for serum testosterone, which was at a low level No consistent changes were found in the eight control athletes.
