1-androstenediol
1-Androstenediol, or 5α-androst-1-ene-3β,17β-diol, also known as 4,5α-dihydro-δ-4-androstenediol, is a prohormone of 1-testosterone (Δ-). It has been used as a dietary supplement, and is identified by the World Anti-Doping Agency as a prohibited substance related to anabolic steroids.

Androgen Prohormone
An androgen prohormone, or proandrogen, is a prohormone (or prodrug) of an anabolic-androgenic steroid (AAS). They can be prohormones of testosterone or of synthetic compound, synthetic AAS, for example, nandrolone (19-nortestosterone). Dehydroepiandrosterone (DHEA), DHEA sulfate (DHEA-S), and androstenedione may all be considered proandrogens of testosterone. In the last two decades, prohormones have also been used by bodybuilders, athletes, and nonmedical users of AAS and other hormones to refer to substances that are expected to convert to active hormones in the body. The intent is to provide the benefits of taking an AAS without the legal risks, and to achieve the hoped-for benefits or advantages without use of AAS themselves. Many of these compounds are legal to manufacture, sell, possess and ingest eliminating the legal problems associated with schedule III AAS. This also enables chemists to further their legal research and get around the law (albeit for a short time). The ty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dietary Supplement
A dietary supplement is a manufactured product intended to supplement a person's diet by taking a pill (pharmacy), pill, capsule (pharmacy), capsule, tablet (pharmacy), tablet, powder, or liquid. A supplement can provide nutrients either extracted from food sources, or that are synthetic (to increase the quantity of their consumption). The classes of nutrient compounds in supplements include vitamins, Dietary mineral, minerals, Dietary fiber, fiber, fatty acids, and amino acids. Dietary supplements can also contain substances that have not been confirmed as being essential to life, and so are not ''nutrients'' per se, but are marketed as having a beneficial biological effect, such as plant pigments or polyphenols. Animals can also be a source of supplement ingredients, such as collagen from chickens or fish for example. These are also sold individually and in combination, and may be combined with nutrient ingredients. The European Commission has also established harmonize ...

World Anti-Doping Agency
The World Anti-Doping Agency (WADA; , AMA) is an international organization co-founded by the governments of over 140 nations along with the International Olympic Committee based in Canada to promote, coordinate, and monitor the fight against drugs in sports. The agency's key activities include scientific research, education, development of anti-doping capacities, and monitoring of the World Anti-Doping Code, whose provisions are enforced by the UNESCO International Convention Against Doping in Sport. The aims of the Council of Europe Anti-Doping Convention and the United States Anti-Doping Agency are also closely aligned with those of WADA. WADA is responsible for the World Anti-Doping Code, adopted by more than 650 sports organisations, including international sports federations, national anti-doping organisations, the IOC, and the International Paralympic Committee. History The World Anti-Doping Agency is a foundation created through a collective initiative led by the na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anabolic Steroid
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). Anabolism, Anabolic Steroid, steroids have a number of medical uses, but are also used by athletes to increase muscle size, strength, and performance. Health risks can be produced by long-term use or excessive doses of AAS. These effects include harmful changes in cholesterol levels (increased low-density lipoprotein and decreased high-density lipoprotein), acne, high blood pressure, hepatotoxicity, liver damage (mainly with most oral AAS), and left ventricular hypertrophy. These risks are further increased when athletes take steroids alongside other drugs, causing significantly more damage to their bodies. The effect of anabolic steroids on the heart can cause myocardial infarction and strokes. Conditions pertaining to hormonal imbalances such as gynecomas ...

1-Androstenedione
1-Androstenedione, or 5α-androst-1-ene-3,17-dione, also known as 4,5α-dihydro-δ1-4-androstenedione, is a Chemical synthesis, synthetic androgen and anabolic steroid. It is a 5α-reductase, 5α-reduced isomer of the endogenous steroid 4-androstenedione and acts as an androgen prohormone of 1-testosterone (4,5α-dihydro-δ1-testosterone), a derivative of dihydrotestosterone (DHT). 1-Androstenedione is on the World Anti-Doping Agency's list of prohibited substances, and is therefore banned from use in most major sports.

Androstanes
An androgen (from Greek ''andr-'', the stem of the word meaning ) is any natural or synthetic steroid hormone that regulates the development and maintenance of male characteristics in vertebrates by binding to androgen receptors. This includes the embryological development of the primary male sex organs, and the development of male secondary sex characteristics at puberty. Androgens are synthesized in the testes, the ovaries, and the adrenal glands. Androgens increase in both males and females during puberty. The major androgen in males is testosterone. Dihydrotestosterone (DHT) and androstenedione are of equal importance in male development. DHT ''in utero'' causes differentiation of the penis, scrotum and prostate. In adulthood, DHT contributes to balding, prostate growth, and sebaceous gland activity. Although androgens are commonly thought of only as male sex hormones, females also have them, but at lower levels: they function in libido and sexual arousal. Andro ...
