Oranabol (Oxymesterone): An Extensive Profile of the Androgenic Anabolic Steroid

Understanding the Background and Pharmacology of Oranabol (Oxymesterone)


In the world of anabolic steroids, Oranabol, also known as Oxymesterone, stands out as a unique and lesser-known compound. In this comprehensive profile, we will delve into the background, chemical structure, pharmacology, medical uses, dosages, side effects, and other essential aspects of Oranabol (Oxymesterone).

Background and Development

Oranabol (Oxymesterone) was first developed in the 1960s by pharmaceutical company Syntex. It is derived from dihydrotestosterone (DHT), making it a DHT-derived anabolic steroid. Oranabol was designed to possess strong anabolic properties with reduced androgenic effects, but it never gained widespread popularity in the medical community. Despite its limited medical use, it has attracted interest from the bodybuilding and athletic communities due to its anabolic potential.

Chemical Structure

The chemical structure of Oranabol (Oxymesterone) is similar to other DHT-derived steroids. It has an added 17-alpha-methyl group, which allows it to be administered orally, as well as a hydroxyl group at the C4 position. This chemical modification enhances its anabolic potency and makes it less susceptible to rapid breakdown in the liver, increasing its bioavailability when taken orally.

Pharmacology and Mechanism of Action

Oranabol (Oxymesterone) exerts its anabolic effects by binding to androgen receptors in target tissues, including muscle cells. This interaction activates specific cellular pathways responsible for increased protein synthesis, nitrogen retention, and muscle growth. Unlike some other anabolic steroids, Oranabol is not significantly aromatized to estrogen, reducing the risk of estrogenic side effects.

Medical Uses

Oranabol (Oxymesterone) was initially used in the medical setting to treat various conditions that required anabolic support. It was prescribed to patients with muscle-wasting diseases, malnutrition, and chronic illnesses. However, due to the availability of more effective and safer treatment options, its medical use has significantly declined over the years.

Dosages and Administration

The typical dosage of Oranabol (Oxymesterone) for medical purposes ranged from 2.5mg to 10mg per day. However, bodybuilders and athletes seeking performance enhancement often use higher dosages, ranging from 10mg to 50mg per day. The administration of Oranabol is generally through oral ingestion, as it is available in tablet form.

Effects and Benefits

Muscle Growth: Oranabol (Oxymesterone) is known for promoting significant muscle growth and increased muscle mass. It enhances protein synthesis and nitrogen retention in muscle tissues, contributing to muscle hypertrophy.

Strength and Power: Users of Oranabol often experience a notable increase in strength and power, which can be beneficial for athletes engaged in strength-based sports and weightlifting.

Enhanced Recovery: Oranabol aids in faster recovery between intense training sessions, reducing muscle fatigue and allowing individuals to train more frequently and intensely.
Boost in Red Blood Cell Production: Oranabol has been shown to increase red blood cell production, leading to improved oxygen-carrying capacity in the blood. This can enhance endurance and overall athletic performance.

Side Effects and Health Risks

As with all anabolic steroids, Oranabol (Oxymesterone) is associated with potential side effects, especially when used at high dosages or for prolonged periods. Common side effects may include:

Androgenic Effects: Androgenic side effects like acne, increased facial and body hair growth, and potential male pattern baldness may occur, particularly in individuals genetically predisposed to such reactions.
Hepatotoxicity: Oranabol is a 17-alpha-alkylated steroid, which can lead to liver strain and potential liver toxicity, especially with long-term use or high doses.

Cardiovascular Issues: Anabolic steroids can impact cholesterol levels, increasing the risk of cardiovascular problems like hypertension and heart disease.

Legal Status and Availability:

Oranabol (Oxymesterone) is a controlled substance in many countries and is not approved for medical use in most regions. Its use for non-medical purposes, such as performance enhancement or bodybuilding, is considered illegal in many places.


Oranabol (Oxymesterone) is a DHT-derived anabolic steroid with potent anabolic effects and reduced androgenic activity. While it was once used in the medical community for various therapeutic purposes, its medical application has significantly declined over the years. Today, Oranabol is not widely available and is considered illegal for non-medical use in many countries. As with any anabolic steroid, informed and responsible use is essential to minimize side effects and ensure safety. Individuals considering the use of Oranabol (Oxymesterone) should seek professional advice and be aware of the legal implications in their respective regions.
