(Dimethazine) Also Under The Brand Name Roxilon
Roxilon, known by the chemical names Dimethazine or Mebolazine, is a synthetic anabolic-androgenic steroid (AAS) designed for muscle building and performance enhancement. This compound is unique because it consists of two methyldrostanolone (Superdrol) molecules linked by a nitrogen atom. This design is believed to make the steroid less hepatotoxic (less damaging to the liver) than other oral steroids, though it still poses significant risks of liver damage among other side effects.
Introduction
Mebolazine, often referred to by its chemical name Dimethazine, is a designer steroid that has gained attention in bodybuilding circles for its strength-boosting and muscle-hardening properties. Originally developed in the 1960s, it was never widely used in mainstream medicine but found a niche among athletes and bodybuilders seeking rapid gains without excessive water retention.
This compound is known for delivering solid, dry muscle mass and enhanced workout performance — but like all anabolic steroids, it comes with potential side effects that require careful consideration.
What is Mebolazine?
Mebolazine is a C17-alpha-alkylated oral anabolic steroid. Structurally, it’s similar to Drostanolone (Masteron) but modified for oral use. Chemically, it’s essentially two Drostanolone molecules bonded together by an azine bridge, which is broken down in the body into active hormone.
Key Benefits for Bodybuilders
1. Lean Muscle Gains
Users often report quality, dense muscle gains rather than puffy, water-retentive size. This makes Mebolazine popular during cutting cycles or pre-contest preparation.
2. Strength Increases
It’s well-regarded for noticeable improvements in lifting strength, aiding progressive overload in the gym.
3. No Aromatization
Mebolazine does not convert to oestrogen, so there’s little risk of water retention, bloating, or gynaecomastia.
4. Stacking Versatility
It stacks well with other non-aromatising compounds for hard, dry physique results, but is also sometimes paired with bulking agents to improve muscle quality.
Typical Usage in Bodybuilding
- Dosage Range: Common anecdotal reports suggest 20–40mg per day for 4–6 weeks.
- Cycle Length: Short cycles are preferred due to its liver toxicity as a 17-aa steroid.
- Stacking Examples: Often used with Testosterone Propionate, Winstrol, or Trenbolone during cutting.
Potential Side Effects
Even though Mebolazine is considered a milder oral steroid in some respects, it can still cause:
- Liver strain (due to its C17-aa nature)
- Increased blood pressure
- Cholesterol imbalance (reduced HDL, increased LDL)
- Suppressed natural testosterone production
- Androgenic effects (acne, hair loss in predisposed individuals)
Post Cycle Therapy (PCT) is essential after use to restore natural hormone levels.
Female Use Considerations
Mebolazine is generally not recommended for women due to its strong androgenic activity and high risk of virilisation (deepened voice, facial hair growth, menstrual disruption). Safer alternatives for females might include low-dose Anavar (Oxandrolone) or Primobolan.
Bodybuilders on various forums often describe Mebolazine as:
- A “dry gainer” — giving strength and visible muscle hardness
- Useful in short bursts before a competition or photo shoot
- Less harsh on the joints than Winstrol
- Best used by those who already have low body fat to fully appreciate its effects
Final Thoughts
Mebolazine (Dimethazine) offers dry, lean muscle growth and significant strength gains without oestrogen-related side effects. However, its liver toxicity and hormonal suppression mean it should be approached cautiously, with proper cycle planning, support supplements, and PCT in place.
It’s a tool for advanced users who understand the risks and want to fine-tune muscle quality rather than gain sheer mass.
Mebolazine (Dimethazine) – Frequently Asked Questions
1. What is Mebolazine?
Mebolazine, also known as Dimethazine, is an oral anabolic steroid originally developed as a prohormone. It’s valued for promoting lean muscle mass, strength, and a hard, dry physique.
2. Is Mebolazine the same as Roxilon?
Yes, Roxilon is a brand name for Mebolazine, containing the same active compound. Some underground labs market it under different brand names.
3. How does Mebolazine work?
Mebolazine binds to androgen receptors, stimulating protein synthesis and nitrogen retention, which helps muscles grow and recover faster.
4. What are the benefits for bodybuilders?
It can help with rapid lean muscle gains, strength increases, reduced water retention, and improved muscle hardness, especially useful in cutting cycles.
5. Can women use Mebolazine?
Generally, it’s not recommended for women due to its high androgenic potential, which can lead to virilisation effects like voice deepening and excess hair growth.
6. What is a common dosage?
Most cycles range from 20–40 mg per day for 4–6 weeks. Higher doses can increase the risk of liver strain and other side effects.
7. Does Mebolazine cause water retention?
No, it does not aromatise into estrogen, so water retention and gynecomastia are not typical concerns.
8. What are the side effects?
Possible side effects include liver toxicity, suppressed testosterone production, increased blood pressure, and cholesterol changes.
9. Do I need Post Cycle Therapy (PCT)?
Yes, a proper PCT is essential to help restore natural testosterone levels after a Mebolazine cycle.
10. Is Mebolazine legal?
Its legal status varies. In many countries, it’s controlled and only legal with a prescription.
