YK11 by Dragon Pharma - Myostatin Inhibition & Extreme Muscle Growth

YK11 by Dragon Pharma is one of the most aggressive muscle-building SARMs available, designed for advanced users who want to push past natural growth limits.
Unlike traditional SARMs that only activate androgen receptors, YK11 works through a unique mechanism - myostatin inhibition. Myostatin is the protein that limits how much muscle your body can build. By suppressing it, YK11 unlocks a new level of hypertrophy, strength, and density that standard compounds simply can't match.

This is why YK11 is often described as a "SARM-steroid hybrid." It delivers rapid visual changes: thicker muscles, harder appearance, and explosive strength gains in a short time frame. Dragon Pharma's tablet-based YK11 provides precise dosing and consistent potency, making it suitable for serious mass phases and aggressive growth cycles.

When myostatin levels drop, muscle cells are allowed to grow larger and stronger without the usual biological brakes. At the same time, YK11 increases follistatin expression - a natural protein that further supports muscle growth and recovery. The result is faster hypertrophy, fuller muscle bellies, and increased training intensity session after session.

YK11 is not a beginner compound. It is built for experienced lifters who already understand SARMs, training volume, nutrition, and recovery. When used correctly, it delivers dramatic size increases while keeping water retention low, producing a dense, dry, "real muscle" look rather than bloated mass.

Key Benefits of YK11 for Muscle Growth

• Suppresses myostatin - removes natural growth limits
• Increases follistatin levels for enhanced hypertrophy
• Rapid lean muscle mass gains
• Significant strength increases
• Dense, dry muscle appearance
• Improves training intensity and workload capacity
• Ideal for advanced bulking or mass-focused recomp cycles

How YK11 Works in the Body

YK11 binds to androgen receptors similarly to SARMs but also activates pathways associated with muscle differentiation and satellite cell activity.
This dual action leads to faster muscle fiber growth and improved recovery between heavy training sessions. Unlike wet bulking compounds, YK11 promotes quality muscle tissue with minimal water retention, making gains easier to maintain after the cycle.

Dosage Recommendations

Begin conservatively, especially if this is your first experience with YK11.

Beginner (advanced SARM user): 5mg per day
Standard dose: 10mg per day
Maximum recommended: 15mg per day (experienced users only)

Cycle length typically ranges from 6 to 8 weeks.
Because YK11 can be suppressive, post-cycle support is strongly recommended after use.

Best Stacks for Extreme Muscle Growth

YK11 stacks best with compounds that support recovery and joint health, as strength gains can increase quickly.

YK11 + MK-677
Boosts GH and IGF-1 to support recovery and muscle fullness.

YK11 + CJC-1295 DAC
Improves recovery, sleep quality, and tissue repair during heavy training phases.

YK11 + BPC-157
Helps protect tendons and joints under increased load.
