Methyltrienolone (Metribolon)

Basic Information

Common Name(s): Methyltrienolone, Metribolone, Methyl Tren Chemical Name: 17β-hydroxy-17α-methyl-estra-4,9,11-trien-3-one Class/Category: Anabolic-Androgenic Steroid (AAS)

Methyltrienolone, commonly known as Metribolone, is considered one of the most potent and toxic oral steroids ever developed. Structurally similar to Trenbolone, it has been modified for oral ingestion, resulting in extreme hepatotoxicity and risks that far outweigh its potential benefits for most users. While its anabolic potential is off the charts, Metribolone is rarely used in bodybuilding except by the most advanced and risk-tolerant individuals.

Pro Tip: Metribolone is a “nuclear option” in the world of steroids. If you’re not prepared to monitor your health obsessively, avoid it altogether.

Administration & Dosage

Metribolone is incredibly potent, and dosages are measured in micrograms (mcg) rather than milligrams.

Dosage Guidelines:

  • Common Range: 500–1000 mcg per day, split into two doses (e.g., morning and pre-workout).
  • Cycle Length: Rarely exceeds 2–3 weeks due to extreme liver toxicity.

Key Considerations:

  • Short Half-Life (~6–8 hours): Splitting doses maintains stable blood levels.
  • Supportive Measures: Liver protection (e.g., TUDCA, NAC) and blood pressure management are non-negotiable.

Pro Tip: Bloodwork before, during, and after your cycle is essential to monitor liver enzymes, lipids, and overall health.

Effects & Experience

Intended Effects:

  1. Extreme Anabolic Potency:
  • Tiny doses yield dramatic strength, muscle hardness, and performance boosts.
  1. Aggression & Drive:
  • Heightened intensity in workouts, though it can spill into irritability outside the gym.
  1. Minimal Water Retention:
  • Offers a dry, hardened look, particularly effective for users already at low body fat levels.

Common Side Effects:

  • Severe Hepatotoxicity:

  • Rapidly elevates liver enzymes. Symptoms like jaundice, dark urine, or abdominal pain are signs of serious damage.

  • High Blood Pressure & Lipid Imbalance:

  • Metribolone can devastate your HDL/LDL profile and spike blood pressure.

  • Androgenic Fallout:

  • Acne, oily skin, hair loss (if predisposed), and extreme aggression/mood swings.

  • Hormone Suppression:

  • Shuts down natural testosterone production, requiring robust PCT.

Pro Tip: Gains are quick but fleeting—many users feel the risks aren’t worth the short-term rewards.

Time Course of Effects:

  • Onset: Strength and aggression ramp up within days.
  • Peak: Effects are consistent throughout the short cycle.
  • After Effects: Expect a steep crash in testosterone and recovery challenges post-cycle.

Stacking

Common Approaches:

  • Solo Use:

  • Due to its extreme potency and toxicity, most users keep Metribolone standalone.

  • Minimal Stacks:

  • A low-dose testosterone base may be added to maintain hormonal function.

Avoid:

  • Combining Metribolone with other hepatotoxic compounds (e.g., Anadrol, Dianabol).
  • Adding multiple strong androgens like high-dose Tren—the synergy could be disastrous.

Pro Tip: Keep stacks minimal and match your cycle length to ensure Metribolone remains the short-term booster.

Safety & Risk Management

Major Risk Factors:

  1. Liver Damage:
  • Metribolone is infamous for being among the most hepatotoxic steroids available.
  • Use liver support supplements (TUDCA, NAC) and keep cycles exceptionally short.
  1. Hormonal Imbalance:
  • Complete shutdown of natural testosterone production requires a robust PCT with SERMs (Clomid, Nolvadex) and potentially hCG.
  1. Blood Pressure & Cardiac Stress:
  • Monitor BP and lipid profiles regularly. Incorporate cardiovascular exercise and a heart-healthy diet.
  1. Psycho-Emotional Impact:
  • Aggression and mood swings can become unmanageable—assess your tolerance early and adjust or stop as needed.

Warning Signs:

  • Fatigue, Nausea, Jaundice:

  • Indicators of acute liver stress. Discontinue use immediately and seek medical attention.

  • Excessive Nosebleeds or Headaches:

  • Likely high blood pressure—adjust dosage or stop use.

  • Severe Mood Swings:

  • Common with strong androgens; reassess your cycle and goals.

Post Cycle Therapy (PCT):

  • Timing:
  • Start PCT 1–2 days after the last dose.
  • Protocol:
  • Use Clomid or Nolvadex to stimulate testosterone recovery.

Pro Tip: Avoid strong compounds post-cycle to allow your body to recover fully.

Final Word

Methyltrienolone (Metribolone) is a last-resort, experimental compound with extreme risks. Even seasoned users often avoid it due to its toxicity. For those who choose to use it, meticulous health monitoring is critical, and cycles must remain short and controlled.

Key Takeaways:

  • Extreme Caution: Metribolone is not a casual steroid—it’s for very advanced users willing to accept significant health risks.
  • Short Cycles Only: Limit to 2–3 weeks with microgram-level dosing.
  • Supportive Measures Required: Use liver aids, monitor blood pressure, and prioritize regular bloodwork.
  • Evaluate the Risks: The fleeting gains may not justify the potential long-term damage.

If you’re determined to experiment, proceed responsibly and prioritize your health over short-term results. Lift hard, but lift smart! 💪
