The typical dosage range of 11-OXO is 300-900 mg/day, depending on what effects the user is looking for. Dosages in the lower end of this range will yield fat loss and a muscle preservation effect while on a restricted calorie diet. Dosages in the higher end of this range will also yield mild gains in strength and possibly size. Because 11-OXO is mild in nature and non-methylated, it can be used for longer cycles than other prohormones, up to 10 weeks in length. Typical cycle length is 5-10 weeks, where a shorter cycle would typically use a higher dose and a longer cycle would typically use a lower dose. Because of Its cortisol controlling effects, taking a dose of 11-OXO after training is a good idea as cortisol levels are elevated at this time. 11-OXO should be taken with a meal containing some fat to help increase absorption.
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.
