YK11 (10MG) (50 TABLETS)

Myostatin Inhibitor & Gene-Selective SARM | Follistatin Expression, Myofibrillar Density & Extreme Muscle Growth

Overview:
YK11 is a unique, steroidal Selective Androgen Receptor Modulator (SARM) that functions simultaneously as a potent Myostatin inhibitor. By binding selectively to androgen receptors in skeletal muscle, YK11 triggers a dramatic upregulation of Follistatin—a naturally occurring glycoprotein that neutralizes Myostatin (the protein that limits genetic muscle growth). This dual-action mechanism allows muscle tissue to bypass standard genetic growth limits, accelerating myofibrillar protein synthesis, muscle cell proliferation, and structural density.

This product is supplied as a secure bottle containing 50 oral tablets, with each tablet accurately dosed at 10mg of active YK11.

Standard SARMs and anabolic agents promote growth primarily through direct androgen receptor stimulation. YK11 takes muscle building a step further by removing the body’s natural genetic brake system (Myostatin) via elevated Follistatin gene expression.

This produces exceptional muscle fullness, rapid power gains, and high-density mass retention even in advanced protocols. The 10mg tablet configuration simplifies daily protocol management, and 50 tablets per bottle provides a complete supply for standard 6- to 8-week breakthrough strength and mass cycles.

• Myostatin Inhibition via Follistatin: Stimulates local Follistatin production to disable the protein restricting muscle hypertrophy.
• Rapid Muscle Mass Accumulation: Drives significant increases in dense, dry muscle tissue without water bloat.
• Extreme Strength & Power Spikes: Rapidly increases heavy compound lifting capacity and muscle fiber contraction force.
• Zero Aromatization: Completely resists conversion into estrogen—no risk of water retention, fluid bloat, or gynecomastia.
• High-Potency 10mg Strength: Provides ideal single-tablet daily dosing for advanced research cycles.

• Half-Life & Timing: YK11 has an estimated active elimination half-life of approximately 6 to 10 hours. Daily intake is typically split into two doses (e.g., 5mg to 10mg morning and evening) with water to keep plasma levels steady.
• Protocol Length: Standard advanced cycles run 6 to 8 weeks maximum due to its high potency.
• Swallowing: Swallow tablets whole with water. Do not crush or chew.

• HPTA Suppression: YK11 is a high-potency compound that causes dose-dependent suppression of natural testosterone levels. A structured Post-Cycle Therapy (SERM-based PCT such as Nolvadex or Clomid) is required post-cycle.
• Joint & Tendon Health: Rapid strength jumps combined with dry tissue gains can place added strain on tendons; pairing with joint support compounds or adequate hydration is recommended.
• Non-Aromatizing: Does not convert to estrogen, but natural hormone suppression during cycle requires proper post-protocol restoration.
