YK 11

What is YK 11?

YK 11 is a selective androgen receptor modulator (SARM) and myostatin inhibitor at 10 mg/tab in a 100-tab pack from Dragon Pharma. Structurally a steroidal SARM, it's used in bodybuilding to promote rapid muscle growth by inhibiting myostatin, a protein that restricts muscle development. As an oral compound, it has moderate hepatotoxicity and does not aromatize, minimizing estrogenic side effects.

What Does YK 11 Do?

YK 11 enhances muscle growth by binding to androgen receptors and inducing follistatin expression, which inhibits myostatin, allowing users to surpass genetic muscle-building limits. It also promotes bone formation and muscle hardening, delivering lean, high-quality gains. Users notice significant size and strength increases within weeks.

Does YK 11 Burn Fat?

YK 11 is not primarily a fat burner but supports fat loss indirectly by increasing muscle mass and metabolic rate. When paired with a calorie-controlled diet, it can enhance body composition, making it effective for lean bulking or cutting cycles.

How Long Does YK 11 Stay in Your System?

YK 11 has a half-life of approximately 12 hours, requiring twice-daily dosing for stable blood levels. It may remain detectable in the body for 1-2 weeks, depending on dosage, individual metabolism, and testing methods. Bloodwork and professional guidance are advised for precise clearance timelines.

Mechanism of Action YK 11

YK 11 binds selectively to androgen receptors, promoting protein synthesis and nitrogen retention for muscle growth. Its unique mechanism induces follistatin expression, inhibiting myostatin to unlock greater muscle-building potential. This dual action (SARM and myostatin inhibitor) results in rapid, lean gains. It has a steroidal backbone but is less suppressive than traditional steroids. Users notice muscle fullness and strength within 1-2 weeks.

How It Works & Key Benefits

YK 11 excels for bodybuilders in bulking or recomp cycles, requiring a high-protein diet and intense training to maximize its anabolic potential.

• Promotes rapid muscle growth via myostatin inhibition.
• Enhances strength for intense workouts.
• Supports lean, dry gains without significant bloating.
• Improves bone health and muscle density.
• Delivers noticeable results in short cycles.
• Stacks effectively for tailored physique goals.

Who It's For & Product Specifications

Best for intermediate to advanced bodybuilders seeking rapid muscle growth and strength; suitable for men and women (with lower doses for women to avoid virilization). Not recommended for beginners or those with liver issues.

What is YK 11 Used For in Bodybuilding?

YK 11 is used in bodybuilding for bulking or recomp cycles to promote rapid muscle growth, enhance strength, and improve body composition by inhibiting myostatin. It's ideal for surpassing genetic muscle limits and achieving lean, high-quality gains.

How to Use

1. Dosage: Men: 10-30 mg/day (1-3 tabs), split into 2 doses (e.g., 5-15 mg morning/evening); Women: 2-5 mg/day (0.2-0.5 tabs). Start low to assess tolerance.
2. Frequency: Twice daily due to 12-hour half-life.
3. Cycle length: 6-8 weeks to minimize liver stress and side effects.
4. Preparation/Monitoring tips: Take with food to reduce GI upset; monitor liver function and testosterone via labs; use liver support (milk thistle, NAC); maintain high-protein diet (2g/kg body weight).
5. Results timeline: Muscle and strength gains in 1-2 weeks; peak results by 4-6 weeks.
6. PCT timing: Start 1-2 days after last dose; use tamoxifen (20-40 mg/day) or clomiphene (50-100 mg/day) for 4-6 weeks, guided by bloodwork.

Popular Stacks

MK-677: Boosts GH and appetite for bulking synergy.

RAD-140: Enhances muscle growth and strength.

Cardarine: Supports fat loss and endurance.

Cycle Support: Protects liver and lipid health during cycles.

Comparisons & Alternatives

YK 11 vs RAD-140: YK 11 uniquely inhibits myostatin for superior muscle growth; RAD-140 is a non-steroidal SARM with less potency but milder side effects.

YK 11 vs LGD-4033: YK 11 offers myostatin inhibition; LGD-4033 is better for straightforward bulking with less suppression.

YK 11 vs Testosterone: YK 11 is less suppressive with targeted effects; Testosterone is broader with estrogenic risks.

Side Effects & Risk Management

• Hepatic: Liver strain—monitor labs, use liver support (milk thistle, NAC).
• Endocrine: Mild testosterone suppression—plan PCT with SERMs.
• Systemic: Joint pain, mild aggression—use joint support, monitor mood.
• Cardiometabolic: Possible lipid changes—monitor labs, use omega-3s.
• Follistatin-Related: Elevated follistatin risks (rare)—monitor health markers.

Review labs with a professional where lawful to ensure authenticity and disciplined dosing for safety. YK 11 is not FDA-approved for human use and is sold for research purposes only.

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 4-6 weeks. Bloodwork guides HPTA recovery, ensuring sustained gains and hormonal balance.
