The Story: In February 2005 Canseco released his autobiography and steroid tell-all, Juiced , Wild Times, Rampant 'Roids, Smash Hits, and How Baseball Got Big. In it he described himself as 'the chemist' having experimented on himself for years. He claimed to have educated and personally injected many players including Mark McGwire, Rafael Palmeiro, Juan Gonzalez, Ivan Rodriguez, and Jason Giambi. In his second book, Vindicated , Canseco added Magglio Ordonez to the list of players he had educated and injected with steroids. He also said he introduced Alex Rodriguez to a trainer/PED supplier after Rodriguez had asked where he could get steroids.
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.
