MK 2866 (Ostarine)

What is MK 2866 (Ostarine)?

MK 2866, or Ostarine (Enobosarm), is a selective androgen receptor modulator (SARM) classified as an oral compound in this 25 mg/tab, 100-tab pack from Dragon Pharma. Developed for muscle-wasting conditions, it's widely used in bodybuilding for lean muscle growth and preservation. As an oral compound, it has minimal hepatotoxicity, no aromatization, and mild HPTA suppression, requiring careful monitoring.

Mechanism of Action MK 2866 (Ostarine)

Ostarine selectively binds to androgen receptors in muscle and bone tissues, promoting protein synthesis and nitrogen retention for lean muscle growth and strength. It minimizes androgenic effects on other tissues, reducing side effects like hair loss or prostate issues. Users notice improved muscle definition and strength within weeks.

With a half-life of approximately 24 hours, Ostarine requires daily dosing for stable blood levels. It doesn't aromatize, avoiding estrogenic side effects, but may cause mild testosterone suppression. What doesn't happen: no significant liver toxicity or estrogenic effects, but PCT may be needed for longer cycles.

Overuse may cause mild suppression or lipid changes, manageable with proper dosing and PCT.

Side Effects & Risk Management

• Endocrine: Mild testosterone suppression—plan PCT for men.
• Cardiometabolic: Minor lipid changes—monitor labs, use omega-3s.

Review labs with a professional where lawful to ensure authenticity and disciplined dosing for safety.

Post-Cycle Therapy (PCT)

Start PCT 1-2 days after last dose due to oral form; use tamoxifen (20-40 mg/day) or clomiphene (50-100 mg/day) for 4 weeks for men. Women may skip PCT unless suppression is evident. Bloodwork guides HPTA recovery, ensuring sustained gains and hormonal balance.
