While the above-mentioned drugs could be considered the basic introductory compounds, they are by no means the only drugs used by women...and this is where the grey area lies! Most women will freely mention the above drugs as part of their cycle. When it comes to contest preparation they'll also talk about Clenbuterol and T3 use (which will be discussed in greater depth in future articles); however, the truth of the matter is that many competitors also use substances like Equipoise, Turinabol, Dianabol and Testosterone. In fact, the use of testosterone by female bodybuilders is perhaps the most closely guarded secret amongst competitors. Those who are willing to talk about its use usually cite the propionate ester as their testosterone of choice with 25-50mg being injected every 5-7 days by the cautious and doses far exceeding this by the highly adventurous (crazy) women.
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.
