Oxymetholone Anadrol: A Comprehensive Review

Anadrol and Dianabol are two of the most popular anabolic steroids used by bodybuilders and athletes who want to increase muscle mass, strength, and performance. Although both drugs belong to the same class—synthetic derivatives of testosterone—they differ in chemical structure, potency, dosing schedule, side-effect profile, legal status, and overall suitability for different training phases. Understanding these differences is essential for anyone considering a steroid cycle or looking to compare how each compound works within a typical bodybuilding program.

Anadrol (Oxymetholone) Steroid – Uses, Side Effects, and More

Primary Uses
Anadrol is a potent anabolic agent known for its ability to rapidly increase lean body mass and enhance muscular strength. It is most frequently used in the following contexts:

- Mass-gaining cycles: The drug’s high anabolic rating (approximately 5–6 on the A/B scale) makes it an ideal choice for athletes seeking quick bulk gains.
- Recovery after injury or surgery: Its ability to stimulate protein synthesis helps accelerate tissue repair and reduce downtime.
- Medical applications: In certain clinical settings, Anadrol is prescribed to treat anemia and cachexia because of its erythropoietic effects (the stimulation of red blood cell production).

Dosing and Cycle Length
Typical anabolic steroid cycles that include Anadrol run for 4–6 weeks. Dosages vary depending on the user’s experience level:

- Beginner: 20–30 mg per day, divided into two doses.
- Intermediate: 40–50 mg per day, split between morning and evening.
- Advanced: 60–70 mg per day for a shorter duration (3–4 weeks) to limit side-effects.

It is common practice to pair Anadrol with an estrogen blocker such as an aromatase inhibitor or a selective estrogen receptor modulator (SERM) because the drug’s estrogenic activity can cause gynecomastia and fluid retention.

Side-Effect Profile
Anadrol carries several notable risks, especially when used in higher doses or for extended periods:

- Estrogenic effects: Gynecomastia, water retention, and bloating are common. Hormonal suppression of the hypothalamic–pituitary axis can also lead to testicular atrophy.
- Liver toxicity: As an oral steroid, Anadrol is hepatotoxic. Regular liver function tests (ALT/AST) are recommended during a cycle.
- Cardiovascular strain: Elevated LDL cholesterol and decreased HDL levels increase the risk of atherosclerosis.
- Psychological changes: Mood swings, aggression (“roid rage”), and anxiety can occur.
- Other effects: Acne, hair loss, and night sweats.

Because of these risks, Anadrol is often considered one of the most “heavy” steroids in terms of both potency and potential harm. Users frequently employ a post-cycle therapy (PCT) regimen to restore natural hormone production after discontinuation.

What is Anadrol?

Anadrol, chemically known as 17α-methyl-2β-hydroxy-androstan-3-one, is an orally active anabolic steroid derived from dihydrotestosterone. The addition of a methyl group at the 17α position protects the molecule from first-pass hepatic metabolism, allowing it to survive in the bloodstream after ingestion. This modification also contributes significantly to its hepatotoxic potential.

Anadrol’s anabolic properties stem from its high affinity for androgen receptors in muscle cells, which triggers an increase in protein synthesis and nitrogen retention. The steroid is also highly estrogenic because testosterone metabolites are converted into estradiol by aromatase; Anadrol enhances this conversion due to its structural similarity with natural testosterone.

Anadrol History and Overview

Anadrol was first synthesized in the 1950s by Dr. Hans Selye and his colleagues at the University of Toronto, who were investigating new anabolic agents for patients suffering from wasting syndromes. The drug entered clinical use under the brand name Anadrol in the early 1960s as a treatment for anemia caused by chronic disease or chemotherapy. Its effectiveness in stimulating erythropoiesis and increasing lean body mass led to broader adoption among athletes, particularly in the United States.

50mg . Food & Drug Administration approved Anadrol for medical use in 1973, but its popularity among bodybuilders surged in the 1980s and 1990s as it became widely available on the black market. Over time, regulatory agencies classified Anadrol as a controlled substance due to its potential for abuse and serious health risks.

Today, Anadrol remains one of the most potent oral anabolic steroids on the market. Its historical significance lies not only in its medical applications but also in how it shaped modern bodybuilding culture by demonstrating that significant muscle gains could be achieved through an oral compound rather than injections alone. Despite its potency, users must weigh the benefits against the increased risk for liver damage and hormonal imbalance.

Anadrol vs Dianabol Cycle

Chemical Nature
- Anadrol: 17α-methylated dihydrotestosterone derivative; highly potent but hepatotoxic.
- Dianabol (Methandrostenolone): 17α-methylated testosterone derivative; moderate potency, less estrogenic than Anadrol.

Potency and Mass Gains
Anadrol typically produces larger mass gains in a shorter time frame because of its higher anabolic rating. Dianabol is still effective but often requires longer cycles or higher doses to match Anadrol’s bulk.

Side-Effect Profile
- Estrogenic side-effects: More pronounced with Anadrol; Dianabol causes mild estrogenic effects, but less severe.
- Liver toxicity: Both are oral steroids and hepatotoxic; however, Anadrol is generally considered more damaging due to its stronger 17α-methyl group.
- Cardiovascular impact: Both raise LDL/HDL ratios, but Anadrol’s effect can be more pronounced.

Cycle Structure
A typical Anadrol cycle may last 4–6 weeks with a total dose of 80–120 mg per week. Dianabol cycles often run for 8–12 weeks at doses ranging from 20–30 mg daily (40–60 mg weekly). Because Dianabol’s half-life is shorter, users sometimes split the dose more frequently.

Hormonal Suppression
Both steroids suppress endogenous testosterone production, but Anadrol’s estrogenic activity can lead to stronger suppression and greater need for post-cycle therapy. Dianabol also requires PCT, though some users report milder suppression.

Use in Combination with Other Steroids
Anadrol is often combined with other aromatase-blocking agents (e.g., anastrozole) or SERMs (tamoxifen) to mitigate gynecomastia and fluid retention. Dianabol can be paired with anabolic steroids like Trenbolone or Testosterone for a “stack” that balances mass gain with strength.

Popularity Among Bodybuilders
- Anadrol: Preferred by bodybuilders looking for rapid, significant size increases during bulking phases.
- Dianabol: Favored by athletes who need quick strength gains and are less concerned about long-term liver damage or estrogenic side-effects; also used as a “first-time” steroid due to its milder profile.

Legal Status
Both Anadrol and Dianabol are classified as Schedule III controlled substances in the United States. Possession without prescription is illegal, and their use can lead to legal penalties and disqualification from professional sports.

Conclusion

When comparing Anadrol and Dianabol cycles, it becomes clear that each steroid serves distinct purposes within a training program. Anadrol’s unparalleled anabolic potency delivers rapid muscle growth but at the cost of higher hepatotoxicity and estrogenic side-effects. Dianabol offers solid mass and strength gains with a slightly lower risk profile, making it suitable for longer cycles or users who wish to avoid extreme liver strain.

Choosing between them requires careful consideration of individual goals, tolerance for side-effects, legal implications, and the ability to manage post-cycle recovery. Both substances demand strict adherence to dosing guidelines, medical monitoring, and a comprehensive support plan—including hormone therapy and lifestyle modifications—to mitigate health risks while achieving desired performance outcomes.
