Anabolic steroids influence cellular differentiation while favoring the development of muscle cells over fat-storage cells. [138] Research in this field has shown that structural modifications in anabolic steroids are critical in determining their binding affinity to ARs and their resulting anabolic and androgenic activities. [82]
Schematic diagram showing anabolism and catabolism. Anabolism (/ ə ˈ n æ b ə l ɪ z ə m /) is the set of metabolic pathways that construct macromolecules like DNA or RNA from smaller units. [1] [2] These reactions require energy, known also as an endergonic process. [3] Anabolism is the building-up aspect of metabolism, whereas catabolism ...

English: *Enzymes, their cellular location, substrates and products in human steroidogenesis. Shown also is the major classes of steroid hormones: progestagens, mineralocorticoids, glucocorticoids, androgens and estrogens.
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). [ 10 ] [ 5 ] It has strong androgenic effects and moderate anabolic effects, which make it useful for producing masculinization and suitable for androgen ...
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): Testosterone derivatives: direct derivatives of testosterone not falling into the groups below
Dehydroepiandrosterone (DHEA), also known as androstenolone, is an endogenous steroid hormone precursor. [4] It is one of the most abundant circulating steroids in humans. [ 5 ] DHEA is produced in the adrenal glands , [ 6 ] the gonads , and the brain. [ 7 ]
An extended or bulkier group at the C17α position reduces AR agonist activity or changes the steroid into an antiandrogen. An ethynyl group (e.g., ethisterone , norethisterone ), allyl group (e.g., allylestrenol ), or vinyl group (e.g., norvinisterone ) all dramatically reduce AR agonist activity.
