Michael A. Ball, DVM, completed an internship in medicine and surgery and an internship in anesthesia at the University of Georgia in 1994, a residency in internal medicine, and graduate work in pharmacology at Cornell University in 1997, and was on staff at Cornell before starting Early Winter Equine Medicine & Surgery located in Ithaca, . He is also an FEI veterinarian and works internationally with the United States Equestrian Team. Ball authored Understanding The Equine Eye , Understanding Basic Horse Care , and Understanding Equine First Aid , published by Eclipse Press and available at or by calling 800/582-5604.
Richard Pound , chairman of the World Anti-Doping Agency and a partner in the Canadian law firm Stikeman Elliott, says: "The use of performance-enhancing drugs is not accidental; it is planned and deliberate with the sole objective of getting an unfair advantage. I don't want my kids, or your kids, or anybody's kids to have to turn themselves into chemical stockpiles just because there are cheaters out there who don't care what they promised when they started to participate. I don't want my kids in the hands of a coach who would encourage, condone or allow the use of drugs among his or her athletes."
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  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.  [ 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 .  : 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.
