Stanozolol

Product Details

Stanozolol (abbrev. Stz), sold under many brand names, is an androgen and anabolic steroid (AAS) medication derived from dihydrotestosterone (DHT). It is used to treat hereditary angioedema. It was developed by American pharmaceutical company Winthrop Laboratories (Sterling Drug) in 1962, and has been approved by the U.S. Food and Drug Administration for human use, though it is no longer marketed in the USA.It is also used in veterinary medicine. Stanozolol has mostly been discontinued, and remains available in only a few countries. It is given by mouth in humans or by injection into muscle in animals.

Stanozolol is a synthetic anabolic steroid derived from dihydrotestosterone (DHT). It is commonly known by its brand name, Winstrol. Stanozolol was developed in the 1960s by Winthrop Laboratories and has been approved for medical use in treating various conditions.

Stanozolol is primarily used to promote weight gain and muscle mass in certain medical conditions like hereditary angioedema and in the treatment of severe burns. However, it is more commonly known for its use in the world of sports and bodybuilding, where it is often used illicitly to enhance athletic performance and improve muscle definition.

Stanozolol works by binding to androgen receptors in the body, which leads to an increase in protein synthesis and nitrogen retention. This helps to build and preserve lean muscle mass. It also has mild androgenic effects, meaning it can promote masculine characteristics such as increased facial hair growth and deepening of the voice.

Unlike most injectable AAS, stanozolol is not esterified and is sold as an aqueous suspension, or in oral tablet form. The drug has a high oral bioavailability, due to a C17α alkylation which allows the hormone to survive first-pass liver metabolism when ingested. It is because of this that stanozolol is also sold in tablet form.

Stanozolol is one of the AAS commonly used as performance-enhancing drugs and is banned from use in sports competition under the auspices of the International Association of Athletics Federations (IAAF) and many other sporting bodies. It is an anabolic steroid that is known to have a diuretic effect. Additionally, stanozolol has been highly restricted in US horse racing.

 

 

 

Stanozolol has been used with some success to treat venous insufficiency. It stimulates blood fibrinolysis and has been evaluated for the treatment of the more advanced skin changes in venous disease such as lipodermatosclerosis. Several randomized trials noted improvement in the area of lipodermatosclerosis, reduced skin thickness, and possibly faster ulcer healing rates with stanozolol. It is also being studied to treat hereditary angioedema, osteoporosis, and skeletal muscle injury.

 

 

Stanozolol is used for physique- and performance-enhancing purposes by competitive athletes, bodybuilders, and powerlifters.

 

 

Stanozolol has high oral bioavailability, due to the presence of its C17α alkyl group and the resistance to gastrointestinal and liver metabolism that it results in. The medication has very low affinity for human serum sex hormone-binding globulin (SHBG), about 5% of that of testosterone and 1% of that of DHT.Stanozolol is metabolized in the liver, ultimately becoming glucuronide and sulfate conjugates. Its biological half-life is reported to be 9 hours when taken by mouth and 24 hours when given by intramuscular injection in the form of an aqueous suspension. It is said to have a duration of action of one week or more via intramuscular injection.

 

 

The protein anabolic ability of Stanozolol is 320% of that of methyltestosterone. It looks very strong, but because Stanozolol has extremely poor affinity with androgen receptors, its real muscle-building ability is not high, and its fat-reducing and water-analyzing abilities are even stronger. protrude. It is generally used as an additive for fat reduction and dehydration.

Stanozolol, commonly known by its brand name Winstrol, is a popular anabolic steroid that has gained significant popularity in the world of bodybuilding and athletics. Several factors contribute to its popularity:

Anabolic Properties: Stanozolol exhibits strong anabolic properties, meaning it promotes muscle growth, protein synthesis, and nitrogen retention. It can help users achieve significant gains in lean muscle mass, making it attractive to bodybuilders and athletes.

Performance Enhancement: Stanozolol is valued for its ability to enhance athletic performance. It can increase strength, speed, and endurance, making it particularly popular among sprinters, track and field athletes, and other sports that require explosive power and speed.

Low Estrogenic Activity: Stanozolol does not aromatize into estrogen, reducing the risk of estrogen-related side effects such as water retention and gynecomastia. This makes it appealing to those seeking a lean, dry, and defined physique.

Oral Administration: Stanozolol is available in both oral and injectable forms. The oral form is favored by some users due to its convenience and ease of administration, as it does not require injections.
