On many ranches, weaned calves go directly from the pasture to the sale barn, where they’re sold at auction, by the pound, to feedlots. The Blairs prefer to own their steers straight through to slaughter and to keep them on the ranch for a couple of months of “backgrounding” before sending them on the 500-mile trip to Poky Feeders. Think of backgrounding as prep school for feedlot life: the animals are confined in a pen, “bunk broken”—taught to eat from a trough—and gradually accustomed to eating a new, unnatural diet of grain. (Grazing cows encounter only tiny amounts of grain, in the form of grass seeds.)
Caught: 6/13/07 , following his 38-second knockout loss against Bernard Ackah at Dynamite!! USA .
Tested positive for: Unspecified anabolic steroids. Morton’s pre-fight urine test came back as positive for a very elevated T/E (testosterone) ratio — , when the average for an athlete is 6.
Punishment: $2,500 fine and an indefinite suspension from the California State Athletic Commission. Morton’s $100,000 purse was also withheld after he refused to take a post-fight drug test. He hasn’t competed since.
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.
