Oxandrolone is a synthetic androstane steroid and a 17α-alkylated derivative of DHT.    It is also known as 2-oxa-17α-methyl-5α-dihydrotestosterone (2-oxa-17α-methyl-DHT) or as 2-oxa-17α-methyl-5α-androstan-17β-ol-3-one, and is DHT with a methyl group at the C17α position and the C2 carbon replaced with an oxygen atom.    Closely related AAS include the marketed AAS mestanolone (17α-methyl-DHT), oxymetholone (2-hydroxymethylene-17α-methyl-DHT), and stanozolol (a 2,3- pyrazole A ring -fused derivative of 17α-methyl-DHT) and the never-marketed/ designer AAS desoxymethyltestosterone (3-deketo-17α-methyl-δ 2 -DHT), methasterone (2α,17α-dimethyl-DHT), methyl-1-testosterone (17α-methyl-δ 1 -DHT), and methylstenbolone (2,17α-dimethyl-δ 1 -DHT).   
It is no secret that bodybuilders and athletes often use steroidal supplements; this is because steroids are known to be an effective aid in getting people their ideal body characteristic. Steroids are hormones that are naturally produced in the body, helping the organs, tissues, and muscles. Artificially-produced steroids, such as anabolic steroids and corticosteroids, are the ones people are most familiar with. Corticosteroids are widely used in the field of medicine as it aids in curing conditions such as allergic rhinitis, hay fever, and asthma. Corticosteroids is an anti-inflammatory medicine that works replicates the hormones naturally produced by your adrenal glands. Unlike corticosteroids, anabolics copy the male sex hormone, testosterone. It is so named because it promotes the body’s anabolic effects such as skeletal muscle growth, and develops male sexual characteristics. Anabolics, however, were initially developed to treat patients with insufficient testosterone in their body, to facilitate normal growth. It is only in recent years that anabolics shifted from its medical use to its potential in bodybuilding.
Anabolic steroids are used by bodybuilders, weightlifters and athletes alike because it supplements the body with more testosterone, and more testosterone means a higher level of endurance and physical performance, as well as muscular growth. The use of this steroidal supplement has been proven to aid in the increase of muscle mass and reduction of body fat. It functions by increasing protein synthesis, which in turn increases training intensity. An increase in training intensity then provides a greater stimulus to your muscles, telling it to adapt by getting stronger. Proper use of this supplement will maximize the effects of your work-out routine, helping you get to that ideal body in a faster and more convenient manner. For some, it is also a plus that an increase of the body’s testosterone levels also boosts your sexual drive and endurance. However, along with the wide use of anabolics are the reported abuses which bring about adverse side effects. A spike in your testosterone level may be well and good to some extent, but too much of it can cause hormonal imbalance, heart problems, and damage to the liver.
