Mibolerone

Basic Information

Common Name(s): Mibolerone, Check Drops Chemical Name: 7α,17α-Dimethyl-19-nortestosterone Class/Category: Anabolic-Androgenic Steroid (AAS)

Mibolerone, commonly known as Check Drops, is one of the most potent and toxic oral steroids available. Originally designed to prevent female dogs from going into heat, it found its way into strength sports for its short-term aggression-boosting effects. However, its extreme hepatotoxicity and cardiovascular risks mean it’s used sparingly, even among advanced users.

Pro Tip: If considering Mibolerone, ensure strict precautions, including liver support and blood pressure monitoring.

Administration & Dosage

Mibolerone is oral with a short half-life (a few hours). Its strength and toxicity require cautious handling.

Dosage Guidelines:

  • Typical Use Scenario:

  • A drop or two (~100–200 mcg) 15–30 minutes pre-workout or pre-competition.

  • Some advanced users may extend to multiple doses over a week, but this is extremely risky.

  • Cycle Length:

  • Not used in traditional cycles—often employed sporadically or for 1–2 weeks maximum.

  • Beginner Warning:

  • There’s no “beginner” approach—Mibolerone is strictly for the ultra-experienced.

Pro Tip: Even limited doses can severely strain your liver. Avoid consecutive daily use and always combine with strong liver support (e.g., TUDCA, NAC).

Effects & Experience

Intended Effects:

  1. Unprecedented Aggression & Drive:
  • Provides explosive mental focus and single-minded determination.
  1. Strength Spike:
  • Users often report a temporary boost in lifting capacity and intensity.
  1. Zero Water Retention:
  • Offers a “dry” effect, though it’s primarily used for its mental and neural push rather than aesthetics.

Common Side Effects:

  • Extreme Hepatotoxicity:

  • Among the harshest orals. Liver enzyme levels can spike dangerously, even with a single dose.

  • Cardiovascular Strain:

  • Can elevate blood pressure, increase heart rate, and disrupt lipid profiles.

  • Androgenic Fallout:

  • Severe acne, oily skin, hair loss (if predisposed), and notable mood swings (aggression/rage).

  • Hormonal Suppression:

  • Even minimal use shuts down natural testosterone production—requires PCT if used repeatedly.

  • Nausea or GI Issues:

  • Some users experience stomach discomfort or sickness due to the compound’s potency.

Onset and Duration:

  • Onset: Aggression and focus typically hit within minutes of ingestion.
  • Duration: Effects last for several hours, but side effects may linger longer.

Pro Tip: The mental edge is powerful, but be prepared for side effects that far outlast the benefits.

Stacking

Typical Usage:

  • Solo Use:

  • Mibolerone is usually taken alone, added to an ongoing injectable cycle for occasional aggression boosts.

  • Minimal Stacking:

  • Advanced users might combine it with a testosterone base for hormonal support, but additional orals or harsh compounds (e.g., Tren, Anadrol) are strongly discouraged.

Avoid: Stacking with other hepatotoxic compounds—Mibolerone alone is already pushing liver health to its limits.

Safety & Risk Management

Major Risk Factors:

  1. Liver Toxicity:
  • The most critical concern. Even a single dose can impact liver health. Use strong liver support (TUDCA, NAC) and monitor enzymes closely.
  1. Cardiovascular Stress:
  • Expect blood pressure spikes and potential arrhythmias. Daily cardiovascular exercise and a heart-healthy diet are strongly advised.
  1. Mood & Behavior Changes:
  • The aggression boost can lead to poor decision-making or interpersonal conflicts.
  1. Hormonal Suppression:
  • Even brief use shuts down endogenous testosterone, necessitating PCT.

Warning Signs:

  • Fatigue, Jaundice, Abdominal Pain:

  • Immediate indicators of liver stress—stop use and seek medical advice.

  • Chest Pain, Heart Palpitations:

  • Signs of cardiovascular strain—discontinue use immediately.

  • Extreme Irritability or Rage:

  • Aggression should stay in the gym. If it spills into daily life, it’s time to stop.

Post Cycle Therapy (PCT):

  • When to Start:

  • If used repeatedly or alongside suppressive compounds, begin PCT 1–2 days after the last dose.

  • Protocol:

  • Use Clomid or Nolvadex to restore natural testosterone production.

Final Word

Mibolerone (Check Drops) is an extremely toxic oral steroid reserved for specific and short-term purposes like aggression boosts for powerlifting or competitions. Even among advanced users, its risks often outweigh the benefits.

Key Takeaways:

  • Extreme Caution Required: Mibolerone is for the highly experienced who can monitor and mitigate its severe side effects.
  • Sporadic Use Only: Avoid prolonged exposure; limit to single doses or very short stints.
  • Prioritize Health: Use liver and cardiovascular supports and never neglect bloodwork.
  • Aggression vs. Health: Ask yourself if the temporary drive is worth the potential long-term damage.

Pro Tip: For most people, safer alternatives like pre-workout supplements, mental preparation, or adrenaline-boosting techniques are better options. Use Mibolerone only as an absolute last resort.
