Steroid isolation , depending on context, is the isolation of chemical matter required for chemical structure elucidation, derivitzation or degradation chemistry, biological testing, and other research needs (generally milligrams to grams, but often more [38] or the isolation of "analytical quantities" of the substance of interest (where the focus is on identifying and quantifying the substance (for example, in biological tissue or fluid). The amount isolated depends on the analytical method, but is generally less than one microgram. [39] [ page needed ] The methods of isolation to achieve the two scales of product are distinct, but include extraction , precipitation, adsorption , chromatography , and crystallization . In both cases, the isolated substance is purified to chemical homogeneity; combined separation and analytical methods, such as LC-MS , are chosen to be "orthogonal"—achieving their separations based on distinct modes of interaction between substance and isolating matrix—to detect a single species in the pure sample. Structure determination refers to the methods to determine the chemical structure of an isolated pure steroid, using an evolving array of chemical and physical methods which have included NMR and small-molecule crystallography . [2] : 10–19 Methods of analysis overlap both of the above areas, emphasizing analytical methods to determining if a steroid is present in a mixture and determining its quantity. [39]


Side-effects from the use of steroids are extremely common and can be quite significant. Most side-effects are reversible once the athlete stops usage although serious long-term side-effects and even death have occurred as a direct result of steroid use.
    •    Decreased sperm production and sex drive

(By David Steen) Anabolic androgenic steroids are synthetic compounds related to the sex hormone testosterone, naturally produced in both male and female bodies. Testosterone-producing organs include adrenal glands, ovaries and especially Leydig cells of male testes. Testosterone, as other steroid hormones, is derived from cholesterol through series of chemical reactions. Testosterone converts into either dihydrotestosterone (DHT), a strong androgen, or to estradiol (a major estrogen) in a process called aromatization. Testosterone and DHT can both activate androgen receptors in certain cells while estradiol activates estrogen receptors...
