This is a complete list of androgens/anabolic steroids (AAS) and formulations that are approved by the FDA Tooltip Food and Drug Administration and available in the United States. AAS like testosterone are used in androgen replacement therapy (ART), a form of hormone replacement therapy (HRT), and for other indications.
As such, the distinction between the terms anabolic steroid and androgen is questionable, and this is the basis for the revised and more recent term anabolic–androgenic steroid (AAS). [70] [75] [218] David Handelsman has criticized terminology and understanding surrounding AAS in many publications.
However, anabolic steroids with a very high ratio of anabolic to androgenic action like nandrolone still have significant androgenic effects and can produce symptoms of masculinization like hirsutism and voice deepening in women and children with extended use.
Metandienone has high oral bioavailability. [1] It has very low affinity for human serum sex hormone-binding globulin (SHBG), about 10% of that of testosterone and 2% of that of DHT. [ 25 ] The drug is metabolized in the liver by 6β- hydroxylation , 3α- and 3β- oxidation , 5β-reduction , 17- epimerization , and conjugation among other ...
This is a list of androgens/anabolic steroids (AAS) or testosterone derivatives. Androgen esters are mostly not included in this list. The major classes of testosterone derivatives include the following (as well as combinations thereof):
Use of high-dose steroids for more than a week begins to produce suppression of the person's adrenal glands because the exogenous glucocorticoids suppress release of hypothalamic corticotropin-releasing hormone (CRH) and pituitary adrenocorticotropic hormone (ACTH). With prolonged suppression, the adrenal glands atrophy (physically shrink), and ...
High-dose progestogen-only contraceptives, such as DMPA, inhibit follicular development and prevent ovulation as their primary mechanism of action. [ 133 ] [ 134 ] The progestogen decreases the pulse frequency of gonadotropin-releasing hormone (GnRH) release by the hypothalamus , which decreases the release of follicle-stimulating hormone (FSH ...
