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. 
NOT NECESSARILY TRUE . Faced with an unnatural rise in estrogen, some steroid users will then take a class of drugs called aromatase inhibitors , which are designed to block the production of estrogen in women with breast cancer, Weinerman says. That's right: It's a breast cancer drug. And aside from the obvious danger in further messing with hormones, guys who turn to aromatase inhibitors can have side effects like joint and muscle pain, the loss of sex drive, and the loss of bone density, which can then result in osteoporosis, according to a Susan G. Komen Foundation report .
DNP is one of if not the most powerful fat burner in history. This compound will see fat, pure body fat melt off the individual’s frame rapidly and abundantly. Further, once the fat is lost it will be very easy to maintain the now lower body fat percentage. This compound literally attacks and destroys fat cells. Consider twenty pounds of pure fat loss in only a few weeks. For that matter consider only half that amount and already you have an extremely appealing fat loss medication. No one can deny DNP is powerfully effective, so effective it’s seemingly magical when we consider the fat loss potential. However, we cannot consider the fat loss potential without recognizing the risks. DNP truly is poison, and it will claim lives. Granted, some will get away with use, this is simply the way many things work in life, but many will not. Even if you follow the guidelines about staying cool and keep your dose at a low to moderate level the risk is still there, you may die.
