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. 
Androx is famous because it was one of the first anabolic steroid where were a mix of 4 different testosterone esters. This preparation contains: testosterone propionate, testosterone isocaproate, testosterone phenylpropionate and testosterone decanoate. It was created for fast and at the same time long action. It is a strong anabolic steroid with well-expressed androgenic component. The active live of this anabolic is approximately 21 days. Once you started a cycle of 8-12 days of injecting, like one time during 5 days of Androx, it will give effective results. In the first 5 days, already you will notice an increase in your weight training. Bodybuilders are using Androx usually to put on mass and size while increasing the strength. Taking Androx even during the first cycle, it can bring very good results in the first cure, even if the dose isn’t so big. Because of its ability to absorb water, this preparation is not suitable for pre-competition preparation in bodybuilding. At the same time, being very a strong androgen, post course therapy should take place approximately 2 weeks after the last injection of the preparation, because it is active during long time in the blood. If you really need extreme volume, then you may combine Androx with Anadrol or Dianabol. But if you need for a clear relief, it could be combined with Trenbolone Mix or of Androx:· Increase of power rate· Increase of muscle mass· Increase of red blood cell formation· Increase of catabolic processes· Increase sexual desire during the cycle, and decline after its completionSpecification:· Active Life - 21 days· Average Dose - 250-1000 mg/weekly· Aromatization - Yes..
Hypercalcemia may develop both spontaneously and as a result of androgen therapy in women with disseminated breast carcinoma. If it develops while on this agent, the drug should be discontinued. Caution is required in administering these agents to patients with cardiac, renal or hepatic disease. Cholestatic jaundice is associated with therapeutic use of anabolic and androgenic steroids. Edema may occur occasionally with or without congestive heart failure. Concomitant administration of adrenal steroids or ACTH may add to the edema. In children, anabolic steroid treatment may accelerate bone maturation without producing compensatory gain in linear growth. This adverse effect may result in compromised adult stature. The younger the child the greater the risk of compromising final mature height. The effect on bone maturation should be monitored by assessing bone age of the wrist and hand every six months. This drug has not been shown to be safe and effective for the enhancement of athletic performance. Because of the potential risk of serious adverse health effects, this drug should not be used for such purpose.
