Quinbolone steroid

Drugs can be added and removed from this list by WADA annually, although not all of the banned substances are explicitly named. Caroline Hatton, PhD , a sports anti-doping science consultant, told in a Mar. 12, 2010 email that "A key concept in prohibited lists is that they avoid being finite. Instead of listing all banned drugs one by one, they list entire drug classes and name drugs merely as examples. This is to keep users who took designer drugs from claiming that they didn't break the rules because the drugs they took weren't listed."

Alkylated testosterone at 17-alpha position such as methyltestosterone show more pharmacologic activity than testosterone itself. Methyltestosterone, a synthetic androgen, is used to treat testosterone deficiency in males. For females it is used in the relief of postpartum breast pain and swelling after pregnancy. It is used to treat the symptom of menopause and in the palliation of certain inoperable breast cancers. Methyltestosterone is a white to creamy white crystalline powder; melting point 162 - 167 C; practically insoluble in water; soluble in various organic solvents; administered orally or sublingually. The chemical designation is 17beta-hydroxy-17alpha-methyl-4-androsten-3-one.

Quinbolone itself has very few androgenic effects, and most of what it does have are a result of its conversion to boldenone and its metabolites . Because of high doses necessary for androgenic effects, cost and inconvenience meant that quinbolone never proved to be commercially successful, and its clinical applications were fulfilled by alternative, more effective, steroids. Its illicit usage in bodybuilding and athletics likewise proved limited, though drug tests are still used to detect its metabolites as it remains a banned substance for most competitive sports.

The disappearance of this product from the black market seemed to go surprisingly unnoticed, probably because athletes usually considered this steroid too mild to warrant consideration. Even when taken in high doses, muscle mass gains would typically be very slight. Clearly this was not simply an alternative to injecting Equipoise, no doubt due to the low bioavailability of this compound. Used in combination with other steroids it might have proven to have solid benefit as an anabolic, but the money would still have been better spent on a number of more cost-effective items. Men who have experimented with this compound generally found a dosage of 80-120 mg (8-12 capsules) per day necessary for any noticeable results. It would obviously not have much use in a bulking cycle, but perhaps the added weak effect might have been welcome during cutting cycles. Women who were curious about steroid use might have found this steroid ideal to experiment with though, perhaps finding notable muscle growth and low side effects on 30-40 mg (3-4 capsules) daily. Of course with its stop in production women are still left with the orals Oxandrolone, Primobolan or Winstrol to fiddle with.

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 [37] 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. [38] [ 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 . [2] :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. [38]
