what kind of substance is an anabolic-androgenic steroid
Anabolic steroid Anabolic steroids, also known more properly as anabolic–androgenic steroids (AAS),[1] 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 cells, especially in skeletal muscles, and also 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. The word anabolic, referring to anabolism, comes from the Greek ἀναβολή anabole, "that which is thrown up, mound". Androgens or AAS are one of three types of sex hormone agonists, the others being estrogens like estradiol and progestogens like progesterone.
Epinephrine Epinephrine, also known as adrenalin or adrenaline, is a hormone, neurotransmitter, and medication.[3][4] Epinephrine is normally produced by both the adrenal glands and certain neurons.[3] It plays an important role in the fight-or-flight response by increasing blood flow to muscles, output of the heart, pupil dilation, and blood sugar.[5][6] It does this by binding to alpha and beta receptors.[6] It is found in many animals and some single cell organisms.[7][8] Napoleon Cybulski first isolated epinephrine in 1895.[9]
