List Of Banned Substances In Baseball
Major League Baseball's drug policy prohibits players from using, possessing, selling, facilitating the sale of, distributing, or facilitating the distribution of any Drug of Abuse and/or Steroid. Any and all drugs or substances listed under Schedule II of the Controlled Substances Act are considered drugs of abuse covered by the Program. Players who require prescription medication can still use it with a "Therapeutic Use Exemption" granted by MLB. In December 2019, MLB removed cannabinoids and added cocaine and opiates to its list of Drugs of Abuse. However, players were told that they could still be suspended for possessing or selling cannabis, or driving under the influence of cannabis.

Major League Baseball
Major League Baseball (MLB) is a professional baseball organization and the oldest major professional sports league in the world. MLB is composed of 30 total teams, divided equally between the National League (NL) and the American League (AL), with 29 in the United States and 1 in Canada. The NL and AL were formed in 1876 and 1901, respectively. Beginning in 1903, the two leagues signed the National Agreement and cooperated but remained legally separate entities until 2000, when they merged into a single organization led by the Commissioner of Baseball. MLB is headquartered in Midtown Manhattan. It is also included as one of the major professional sports leagues in the United States and Canada. Baseball's first all-professional team, the Cincinnati Red Stockings, was founded in 1869. Before that, some teams had secretly paid certain players. The first few decades of professional baseball were characterized by rivalries between leagues and by players who often jumped from on ...

Codeine
Codeine is an opiate and prodrug of morphine mainly used to treat pain, coughing, and diarrhea. It is also commonly used as a recreational drug. It is found naturally in the sap of the opium poppy, ''Papaver somniferum''. It is typically used to treat mild to moderate degrees of pain. Greater benefit may occur when combined with paracetamol (acetaminophen) or a nonsteroidal anti-inflammatory drug (NSAID) such as aspirin or ibuprofen. Evidence does not support its use for acute cough suppression in children or adults. In Europe, it is not recommended as a cough medicine in those under 12 years of age. It is generally taken by mouth. It typically starts working after half an hour, with maximum effect at two hours. Its effects last for about four to six hours. Codeine exhibits abuse potential similar to other opioid medications. Common side effects include vomiting, constipation, itchiness, lightheadedness, and drowsiness. Serious side effects may include breathing difficult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bolasterone
Bolasterone (, ) (brand names Myagen, Methosarb; former developmental code name U-19763), also known as 7α,17α-dimethyltestosterone, is a 17α-alkylated androgen/anabolic steroid (AAS) which is used in veterinary medicine. It has close structural similarity to testosterone, and like methyltestosterone has a methyl group at C17α in order to increase oral bioavailability. In addition, it is also 7α-methylated, similar to its 7β-methylated isomer calusterone. The medication has a low to moderate ratio of anabolic to androgenic activity, similar to that of fluoxymesterone. Bolasterone is on the World Anti-Doping Agency The World Anti-Doping Agency (WADA; french: Agence mondiale antidopage, AMA) is a foundation initiated by the International Olympic Committee based in Canada to promote, coordinate, and monitor the fight against drugs in sports. The agency's k ...'s list of prohibited substances, and is therefore banned from use in most major sports. References Andr ...

Bolandiol
Bolandiol (INN, also known as 19-nor-4-androstenediol, estr-4-ene-3β,17β-diol, or 3β-dihydronandrolone) is an anabolic-androgenic steroid (AAS) that was never marketed. However, a dipropionate ester derivative, bolandiol dipropionate, has been marketed. Bolandiol and its dipropionate ester are unique among AASs in that they reportedly also possesses estrogenic and progestogenic activity. Bolandiol is on the World Anti-Doping Agency's list of prohibited substances, and is therefore banned from use in most major sports. It is a potential metabolic precursor to nandrolone. However, several clinical studies have concluded that bolandiol does not alter strength, body composition, or exercise performance. See also * 4-Androstenediol * 19-Nor-5-androstenediol * 19-Nor-5-androstenedione * Bolandione (19-nor-4-androstenedione) * Bolenol Bolenol (, ), also known as 17α-ethyl-19-norandrost-5-en-17β-ol (ethylnorandrostenol), is a synthetic, orally active anabolic-androgenic ste ...

Androstenetrione
4-Androstene-3,6,17-trione (4-AT; also marketed as 6-OXO or 4-etioallocholen-3,6,17-trione) is a drug or nutritional supplement that may increase the testosterone-estrogen ratio, but has no proven effect on body composition. Its use can be detected in urine. 4-AT is a potent irreversible aromatase inhibitor that inhibits estrogen biosynthesis by permanently binding and inactivating aromatase in adipose and peripheral tissue. Aromatase is responsible for the conversion of testosterone to estradiol. Blocking aromatase causes the body to decrease in levels of estradiol, which then results in increase of LH and consequently, testosterone. Since testosterone has myotropic activity and estradiol does not, elevated testosterone levels increase muscle mass. However, there appear to be no human or animal studies testing the hypothesis that 4-AT will produce an anabolic effect. 4-AT is used by steroid or prohormone users to counteract estrogen level increases caused by aromatizati ...

Androstenedione
Androstenedione, or 4-androstenedione (abbreviated as A4 or Δ4-dione), also known as androst-4-ene-3,17-dione, is an endogenous weak androgen steroid hormone and intermediate in the biosynthesis of estrone and of testosterone from dehydroepiandrosterone (DHEA). It is closely related to androstenediol (androst-5-ene-3β,17β-diol). Biological function Androstenedione is a precursor of testosterone and other androgens, as well as of estrogens like estrone, in the body. In addition to functioning as an endogenous prohormone, androstenedione also has weak androgenic activity in its own right. Androstenedione has been found to possess some estrogenic activity, similarly to other DHEA metabolites. However, in contrast to androstenediol, its affinity for the estrogen receptors is very low, with less than 0.01% of the affinity of estradiol for both the ERα and ERβ. Adrenarche In children aged 6 to 8 years old, there is a rise in androstenedione secretion along with DH ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Androstenediol
Androstenediol, or 5-androstenediol (abbreviated as A5 or Δ5-diol), also known as androst-5-ene-3β,17β-diol, is an endogenous weak androgen and estrogen steroid hormone and intermediate in the biosynthesis of testosterone from dehydroepiandrosterone (DHEA). It is closely related to androstenedione (androst-4-ene-3,17-dione). Biological activity Androstenediol is a direct metabolite of the most abundant steroid produced by the human adrenal cortex, DHEA. It is less androgenic than the related compound, Δ4-androstenediol, and has been found to stimulate the immune system. When administered to rats, androstenediol, '' in vivo'', has approximately 1.4% of the androgenicity of DHEA, 0.54% of the androgenicity of androstenedione, and 0.21% of the androgenicity of testosterone. Androstenediol possesses potent estrogenic activity, similarly to DHEA and 3β-androstanediol. It has approximately 6% and 17% of the affinity of estradiol at the ERα and ERβ, respective ...

Androstanedione
Androstanedione, also known as 5α-androstanedione or as 5α-androstane-3,17-dione, is a naturally occurring androstane (5α-androstane) steroid and an endogenous metabolite of androgens like testosterone, dihydrotestosterone (DHT), dehydroepiandrosterone (DHEA), and androstenedione Androstenedione, or 4-androstenedione (abbreviated as A4 or Δ4-dione), also known as androst-4-ene-3,17-dione, is an endogenous weak androgen steroid hormone and intermediate in the biosynthesis of estrone and of testosterone from dehy .... It is the C5 epimer of etiocholanedione (5β-androstanedione). Androstanedione is formed from androstenedione by 5α-reductase and from DHT by 17β-hydroxysteroid dehydrogenase. It has some androgenic activity. In female genital skin, the conversion of androstenedione into DHT through 5α-androstanedione appears to be more important than the direct conversion of testosterone into DHT.

Androstadienedione
Boldione, also known as androstadienedione or 1-dehydroandrostenedione, as well as 1,4-androstadiene-3,17-dione, is an important industrial precursor for various steroid hormones. In the United States the chemical is regulated as a Schedule III Controlled Substance. Uses Androstadienedione is an important industrial-scale precursor for a wide variety of steroid hormones within the estrane and androstane classifications. Preparation Androstadienedione is obtained in high yield from both plant and animal sterols by biotransformation. The chemical is a common byproduct derived from other processes (e.g. vegetable oil deodorization and the production of lanolin from wool processing). The product is produced in a single step via a simultaneous side-chain cleavage at the C17 position and an alcohol oxidation in the C3 position. Regulation United States In 2004 the United States Congress passed the Anabolic Steroid Control Act of 2005 which placed 36 steroids and over-the-counter ...

Phencyclidine
Phencyclidine or phenylcyclohexyl piperidine (PCP), also known as angel dust among other names, is a dissociative anesthetic mainly used recreationally for its significant mind-altering effects. PCP may cause hallucinations, distorted perceptions of sounds, and violent behavior. As a recreational drug, it is typically smoked, but may be taken by mouth, snorted, or injected. It may also be mixed with cannabis or tobacco. Adverse effects may include seizures, coma, addiction, and an increased risk of suicide. Flashbacks may occur despite stopping usage. Chemically, PCP is a member of the arylcyclohexylamine class, and pharmacologically, it is a dissociative anesthetic. PCP works primarily as an NMDA receptor antagonist. PCP is most commonly used in the United States. While usage peaked in the US in the 1970s, between 2005 and 2011 an increase in visits to emergency departments as a result of the drug occurred. As of 2017 in the United States, about 1% of people i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
