Furazadrol
Active Substance: Furazadrol
Description
Furazadrol: An Overview
Furazadrol is a designer anabolic-androgenic steroid (AAS). It has been found in "dietary supplements" and is not an approved medication for human use. Its chemical structure is related to the drug danazol, and it is known for having a high anabolic-to-androgenic ratio.
Different Name: Furazadrol is also known by its systematic name: [1′,2′]isoxazolo[4′,5′:2,3]-5α-androstan-17β-ol. It is sometimes found as a mixture of isomers, with isofurazadrol being a related compound.
Side Effects and Benefits
Benefits:
-
Anabolic Activity: Furazadrol is reported to have noteworthy anabolic activity, meaning it can promote muscle growth.
-
Reduced Estrogen: It has been reported to effectively reduce estrogen biosynthesis, which can be a desirable effect for bodybuilders seeking to avoid water retention and gynecomastia (enlarged male breasts).
-
Increased Endogenous Steroids: It may significantly increase levels of endogenous steroids like dihydrotestosterone (DHT) and testosterone.
Side Effects:
As a powerful anabolic-androgenic steroid, Furazadrol likely shares many of the same side effects as other AAS, which can range from mild to severe and life-threatening. These can include:
-
Cardiovascular: High blood pressure, heart attack, and stroke.
-
Hepatic (Liver): Liver damage.
-
Neuropsychiatric: Mood swings, aggression, irritability, and depression.
-
Endocrine: Suppression of natural hormone production, testicular atrophy (in men), and menstrual cycle changes (in women).
-
Dermatological: Severe acne, oily skin, and male-pattern baldness.
-
Musculoskeletal: Weakening of muscles with long-term use.
Pros and Cons
Pros:
-
Potent Anabolic Effects: Can lead to significant increases in lean muscle mass and strength.
-
Anti-estrogenic Properties: Helps to avoid side effects related to high estrogen levels.
-
Oral Activity: Can be taken orally, which is more convenient for some users than injections.
Cons:
-
Illegality and Lack of Regulation: Furazadrol is not a legal or regulated substance for human use, meaning its purity, dosage, and safety are not guaranteed.
-
Serious Health Risks: The potential for severe and life-threatening side effects is a major concern.
-
No Clinical Studies: There is a lack of clinical studies on its safety and long-term effects on humans.
-
Detection in Drug Testing: It is a designer steroid and is actively screened for in anti-doping tests.
Dosage and Frequency
There is no standardized or medically recommended dosage for Furazadrol because it is not a prescription medication. Information on typical dosages and cycles is found only in unofficial sources, often from bodybuilding communities, and should be considered with extreme caution due to the high risks involved.
Half-Life and Detection Time
-
Half-Life: Specific information on the half-life of Furazadrol in humans is not widely available. However, as an oral steroid, its half-life is likely to be relatively short, often measured in hours.
-
Detection Time: The detection time for steroids varies significantly based on factors such as the specific drug, dosage, frequency of use, and individual metabolism. Oral steroids can be detectable in urine for several weeks (approximately 3-8 weeks), and certain metabolites can be detected for even longer. Hair and nail testing can detect steroid use for months to over a year.
Progestogenic and Prolactin Effects
-
Progestogenic Effects: The provided search results do not directly specify the progestogenic effects of Furazadrol. However, some anabolic steroids can have progestogenic activity, which can lead to side effects like gynecomastia, especially when combined with estrogenic activity.
-
Prolactin Effects: Similarly, the specific prolactin effects of Furazadrol are not detailed in the provided information. Some compounds can increase prolactin levels, leading to side effects such as galactorrhea (inappropriate lactation) and sexual dysfunction.
Anabolic-Androgenic Ratio
The anabolic-androgenic ratio is a measure of a steroid's ability to promote muscle growth (anabolic) versus its ability to produce male characteristics (androgenic). For Furazadrol, there is no widely cited, specific numerical ratio. However, it is generally described as having a high anabolic-to-androgenic ratio, which means its effects are primarily geared toward muscle building with less pronounced androgenic side effects. It is important to note that even with a "favorable" ratio, androgenic effects are still present and can be significant, especially at high doses.
