Anabolic steroids, also known as anabolic-androgenic steroids (AAS), are a class of drugs that are structurally related to testosterone, the main male sex hormone, and produce effects by binding to the androgen receptor (AR). Anabolic steroids have a number of medical uses, [ 1 ] but are also used by athletes to increase muscle size, strength ...
Andro, DHEA, stanozolol, testosterone, and nandrolone, or derivates (see below) are banned anabolic steroids. Other banned anabolic agents include clenbuterol, tibolone, zeranol, zilpaterol, and selective androgen receptor modulators. [7] While a few of the banned drugs are endogenous, that is they are normally produced in the human body, most ...
Selective androgen receptor modulators (SARMs) are a novel class of androgen receptor ligands. They are intended to maintain the desirable muscle building effects of anabolic steroids while reducing undesirable androgenic actions (e.g., increased risk of prostate cancer).
Anabolic Steroids. When Arnold ruled the Mr. Olympia stage in the 1970s, steroid use was basic and legal. “You took one or two doses at a time, and the total amount most guys used per week was ...
Performance-enhancing substances, also known as performance-enhancing drugs (PEDs), [1] are substances that are used to improve any form of activity performance in humans. Many substances, such as anabolic steroids, can be used to improve athletic performance and build muscle, which in most cases is considered cheating by organized athletic ...
Estrogenic side effects such as gynecomastia and fluid retention can also occur. [1] Case reports of gynecomastia exist. [21] [22] As with other 17α-alkylated steroids, methandienone poses a risk of hepatotoxicity and use over extended periods of time can result in liver damage without appropriate precautions. [1]
Oxandrolone is an androgen and synthetic anabolic steroid (AAS) medication to help promote weight gain in various situations, to help offset protein catabolism caused by long-term corticosteroid therapy, to support recovery from severe burns, to treat bone pain associated with osteoporosis, to aid in the development of girls with Turner syndrome, and for other indications.
Nandrolone is an agonist of the AR, the biological target of androgens like testosterone and DHT. Unlike testosterone and certain other anabolic steroids, nandrolone is not potentiated in androgenic tissues like the scalp, skin, and prostate, hence deleterious effects in these tissues are lessened.
