The use of Clenbuterol Hydrochloride also carries with it possible side effects that can be severe; in fact, dangerous would be a more accurate description. Such effects are most commonly associated with abuse through high doses and far beyond recommended extended periods of use. The severe side effects of Clenbuterol include high blood pressure, irregular heartbeat, trembling and even panic. Some studies have also shown that Clenbuterol abuse can also lead to cardiac hypertrophy, which could potentially lead to death. It is very possible to use this compound without such effects, but as with so many things in life it will require responsible use and a thorough understanding of Clen.
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.
