Halodrol
Active Substance: Halodrol
Description
What is Halodrol?
Halodrol, also known by its chemical name chlorodehydromethylandrostenediol (CDMA), is a synthetic, orally active anabolic-androgenic steroid (AAS). It is a derivative of a well-known steroid, chlorodehydromethyltestosterone (Oral Turinabol).
Halodrol was briefly sold as a "dietary supplement" or "prohormone" in the mid-2000s before a 2014 prohormone ban. Despite being marketed as a prohormone (a precursor to a hormone), it is a potent anabolic-androgenic steroid in its own right. Due to its chemical structure, it cannot be aromatized into estrogen, which means it doesn't cause estrogenic side effects like gynecomastia (enlargement of male breast tissue).
Benefits and Side Effects
Benefits
Halodrol is an anabolic steroid, meaning it promotes anabolism, or the building of muscle tissue. Users report benefits such as:
-
Muscle Growth: Increased protein synthesis leads to accelerated muscle development.
-
Strength Gains: It can contribute to an increase in muscular strength and endurance.
-
Fat Loss: It may help to reduce body fat percentage while gaining muscle mass.
-
Anti-Catabolic Effects: It may help to preserve muscle tissue, especially during periods of stress or caloric restriction.
Side Effects
As a 17$\alpha$-alkylated oral steroid, Halodrol is known to be hepatotoxic, meaning it can cause liver damage. Other side effects can include:
-
Liver Toxicity: This is a major concern with Halodrol and other oral steroids. Long-term use can lead to liver tumors or blood-filled cysts.
-
Androgenic Side Effects: While it has a relatively high anabolic-to-androgenic ratio, it can still produce androgenic side effects. These include oily skin, acne, and increased growth of facial and body hair.
-
Virilization in Women: In women, Halodrol can cause irreversible masculine features, such as a deepened voice, increased facial hair, male-pattern baldness, and an enlarged clitoris.
-
Cardiovascular Risks: Steroid use can increase the risk of heart disease, hypertension, and other cardiovascular issues.
-
Hormonal Imbalances: It can suppress the body's natural production of testosterone, leading to hypogonadism (reduced function of the testes). This can result in infertility and other issues.
-
Behavioral Changes: Halodrol can cause mood swings and increased aggression.
Pros and Cons
Pros
-
Muscle and Strength Gains: Effective for promoting muscle growth and strength.
-
No Estrogenic Side Effects: Cannot be aromatized into estrogen, so it doesn't cause gynecomastia or water retention.
-
Oral Administration: Convenient to take as a pill.
Cons
-
Illegal and Unregulated: It is a controlled substance and is illegal to include in supplement products. This means that products sold online may be counterfeit, mislabeled, or contain other dangerous substances.
-
Hepatotoxicity: Poses a significant risk of liver damage.
-
Androgenic Side Effects: Can still cause side effects like acne and hair loss.
-
Hormonal Suppression: Can shut down natural hormone production, requiring post-cycle therapy to restore normal function.
-
Lack of Scientific Evidence: There is limited reliable scientific information about its use, and there is no safe or appropriate dosage.
Dosage and Frequency
There is no reliable medical information on an appropriate dosage for Halodrol because it has never been approved for medical use. Any dosage information is based on anecdotal reports from users and is not supported by scientific research. Due to its potential for serious side effects, it is not recommended for use.
Half-Life and Detection Time
-
Half-Life: Approximately 16 hours.
-
Detection Time: The detection time for Halodrol is not definitively established in publicly available sources. However, as with other anabolic steroids, its metabolites can be detectable in urine for weeks or even months after a single dose.
Sterogenic, Progestronic, and Prolactin Effects
-
Estrogenic Effects: Halodrol cannot be aromatized into estrogen due to its chemical structure. Therefore, it does not cause estrogenic side effects.
-
Progestronic Effects: Halodrol does not have significant progestogenic activity.
-
Prolactin Effects: It is not known to directly affect prolactin levels. However, hormonal imbalances caused by anabolic steroid use can indirectly impact other endocrine functions.
Anabolic-Androgenic Ratio
The reported anabolic-androgenic ratio for Halodrol is approximately 74:28. This means it is considered to have a strong anabolic effect with a moderate androgenic effect. This is often compared to a ratio of 1:1 for testosterone.
