Anadrol
Active Substance: Anadrol
Description
Anadrol (Oxymetholone) is a potent synthetic anabolic-androgenic steroid (AAS) derived from dihydrotestosterone (DHT). It is a Schedule III controlled substance in the United States, meaning it has accepted medical uses but also a potential for abuse.
What is Anadrol?
Anadrol, also known by its generic name Oxymetholone, was originally developed in the 1960s to treat severe cases of anemia and muscle wasting diseases like AIDS. It works by stimulating the production of red blood cells (erythropoiesis) and increasing protein synthesis. While it has legitimate medical applications, it is also widely misused by athletes and bodybuilders for its powerful muscle-building and performance-enhancing effects.
Side Effects and Benefits
Benefits:
-
Rapid Muscle Growth and Strength Gains: Anadrol is well-known for its ability to produce significant and rapid increases in muscle mass and strength. This is one of the primary reasons for its use in bodybuilding.
-
Increased Red Blood Cell Production: Medically, this is the main benefit, as it helps treat anemia by increasing the body's red blood cell count, which in turn improves oxygen delivery to muscles and tissues.
-
Enhanced Appetite: It can help individuals with muscle wasting conditions by stimulating their appetite, leading to increased caloric intake and weight gain.
-
Improved Recovery: By increasing protein synthesis and red blood cell count, it can help the body recover more quickly from intense workouts.
Side Effects:
Anadrol is a potent and hepatotoxic (toxic to the liver) oral steroid, and its use is associated with a wide range of significant and potentially severe side effects.
-
Hepatic Toxicity: This is one of the most concerning side effects. Long-term use or high doses can lead to liver damage, including liver tumors, peliosis hepatis (blood-filled cysts in the liver or spleen), and cholestatic jaundice (yellowing of the skin and eyes).
-
Androgenic Side Effects: These are related to the development of male characteristics and can be particularly pronounced.
-
In men: Gynecomastia (development of breast tissue), male pattern baldness, and suppression of natural testosterone production, which can lead to testicular atrophy.
-
In women: Virilization, which can be irreversible even after stopping the drug. This includes a deepened voice, increased facial and body hair (hirsutism), male pattern baldness, and clitoral enlargement.
-
-
Cardiovascular Side Effects: Anadrol can negatively impact cholesterol levels, increasing LDL ("bad") cholesterol and decreasing HDL ("good") cholesterol, which raises the risk of cardiovascular disease.
-
Estrogenic Side Effects: Although Anadrol does not aromatize (convert to estrogen) itself, it can cause water retention and bloating, a common side effect of high estrogen levels. The exact mechanism for this is not fully understood, but it is believed to be related to its progestogenic or other direct effects on estrogen receptors.
-
Other Side Effects:
-
Nausea, vomiting, diarrhea, and loss of appetite.
-
Insomnia and mood changes, including irritability and aggression ("roid rage").
-
High blood pressure.
-
Acne.
-
Suppression of the hypothalamic-pituitary-testicular axis (HPTA), leading to a decline in natural hormone production.
-
Pros and Cons
Pros:
-
Extremely effective for rapid muscle mass and strength gains.
-
Stimulates appetite.
-
Increases red blood cell production, which can improve endurance.
Cons:
-
Highly hepatotoxic (damaging to the liver).
-
Severe and potentially irreversible androgenic side effects, especially in women.
-
Significant cardiovascular risks.
-
High potential for water retention and bloating.
-
Suppresses natural hormone production.
-
Requires a post-cycle therapy (PCT) to help restore natural testosterone levels.
Dosage and Frequency
Medically, the dosage of Anadrol for treating anemia is typically 1-5 mg/kg of body weight per day. However, in the context of performance enhancement, doses are often much higher, ranging from 50 to 150 mg per day. The typical frequency is once daily due to its half-life. Due to its hepatotoxicity, cycles are usually kept short, no more than 4-6 weeks. It is important to note that these are not medical recommendations and such use is not approved by regulatory bodies.
Half-Life and Detection Time
-
Half-Life: The half-life of Anadrol (Oxymetholone) is approximately 8-9 hours. This means that half of the drug is eliminated from the body within this timeframe.
-
Detection Time: Due to its chemical properties and metabolites, Anadrol has a relatively long detection time. It can be detectable in urine drug tests for up to 2 months after the last dose.
Sterogenic, Progestogenic, and Prolactin Effects
-
Sterogenic: This refers to its general properties as an anabolic steroid. It binds to androgen receptors to promote anabolism (tissue building) and androgenic effects.
-
Progestogenic: Anadrol is not a progestin, and it does not directly bind to the progesterone receptor. However, some sources suggest it may have progestogenic-like effects, which could contribute to some of its side effects, such as water retention and gynecomastia.
-
Prolactin: Anadrol is not known to have a direct effect on prolactin levels. However, some studies suggest that other androgens can cause an increase in prolactin, which can lead to galactorrhea (milky nipple discharge) and erectile dysfunction.
Anabolic Androgenic Ratio
The anabolic-androgenic ratio is a measure of a steroid's anabolic (muscle-building) effects versus its androgenic (masculinizing) effects, typically compared to testosterone, which has a ratio of 100:100.
Anadrol (Oxymetholone) is considered to have a very high anabolic rating, but it also has a significant androgenic rating. While some sources may provide varying figures, its anabolic to androgenic ratio is often cited as being around 320:45, indicating it is much more anabolic than it is androgenic. However, its high anabolic potency is often accompanied by significant androgenic side effects, which can be due to its interaction with other hormones and its overall potency.
