MK 2866

MK-2866 (Ostarine) is a Selective Androgen Receptor Modulator (SARM) designed to mimic the effects of anabolic steroids with fewer side effects. It selectively targets androgen receptors in muscle and bone, promoting growth and repair while sparing other tissues.

How It Works:

• Binds to androgen receptors in muscle and bone, stimulating protein synthesis and bone density without converting to estrogen or DHT.

Uses:

1. Medical Applications (under research):

   • Muscle Wasting: Treats conditions like cachexia (muscle loss) in chronic diseases.
   • Osteoporosis: Increases bone density and reduces fracture risk.

2. Fitness/Bodybuilding (off-label):

   • Lean Muscle Gain: Supports muscle growth during bulking phases.
   • Fat Loss: Preserves muscle during calorie deficits in cutting phases.
   • Recovery: Speeds up healing from injuries or intense workouts.

Dosage:

• Typical dose: 10–30 mg daily, depending on goals and experience.
• Cycle length: 6–12 weeks, followed by Post-Cycle Therapy (PCT) to restore natural testosterone.

Benefits:

• Promotes lean muscle growth and fat loss.
• Enhances strength and endurance.
• Reduces muscle wasting and improves recovery.
• Minimal side effects compared to anabolic steroids.

Side Effects:

• Suppression: May partially suppress natural testosterone production, especially at higher doses.
• Potential Risks: Long-term safety is unknown; some users report joint pain or fatigue.
• Other: Risk of liver toxicity with high doses or prolonged use.
