   1. Product Overview 

Myosarm (YK-11) is a unique SARM with dual-action potential—it not only binds androgen receptors but also inhibits myostatin, promoting muscle growth and bone density in research models. Lawless Labs offers it in these research-grade formats:

  1. Tincture – 10 mg/mL, 30 mL bottle
  2. Capsules – 90 capsules, 5 mg per capsule
    3. Raw Powder – 1,000 mg pure crystalline YK-11 

All products are lab-tested, third-party verified, and packaged to maintain integrity.

   2. Chemical & Physical Data

CAS:

431579-34-9

Molecular Formula:

C₂₅H₃₄O₆

Molar Mass:

~430.54 g/mol

Appearance:

Off-white to beige crystalline powder (capsule/powder) or PEG400-based solution (tincture)

Solubility:

Soluble in ethanol, DMSO, PEG400; sparingly soluble in water

Bioactivity:

Binds androgen receptors and inhibits myostatin, enhancing muscle cell growth, strength, and bone density

   3. Research Significance

YK-11 is notable for its potential to surpass traditional SARMs in anabolic efficacy, thanks to its myostatin-inhibiting mechanism. This makes it a compelling compound for studies on muscle hypertrophy, bone integrity, and metabolic signaling. Preclinical findings show superior anabolic effects compared to testosterone and conventional SARMs.
