The most commonly used AAS in medicine are testosterone and its various esters (but most commonly testosterone undecanoate , testosterone enanthate , testosterone cypionate , and testosterone propionate ),  nandrolone esters (most commonly nandrolone decanoate and nandrolone phenylpropionate ), stanozolol , and metandienone (methandrostenolone).

Dihydrotestosterone (DHT; androstanolone, stanolone) and its esters are also notable, although they are not widely used in medicine.

This is accomplished by blocking/minimizing the effects of estrogen in the body. To be more specific Clomid is chemically a synthetic estrogen with both agonist/antagonist properties, and is very similar in structure and action to Nolvadex. In certain target tissues it can block the ability of estrogen to bind with its corresponding receptor. Its clinical use is therefore to oppose the negative feedback of estrogens on the hypothalamic-pituitary-ovarian axis, which enhances the release of LH and FSH. This of course can help to induce ovulation.
