Core Effects

YK11 is a selective androgen receptor modulator (SARM) that is widely used in muscle hypertrophy research, muscle atrophy treatment, and athletic performance enhancement due to its unique myostatin inhibition mechanism and partial agonist properties .

✅ Dual mechanism of action :

Myostatin inhibition : Inhibits the myostatin signaling pathway, thereby relieving muscle growth restriction.

Partial agonist : As a partial agonist of androgen receptors, it promotes muscle protein synthesis.

Gene expression : Upregulation of myogenic regulatory factors (MRFs) expression

✅Quality advantages of Chinese manufacturing :

Purity Guarantee : Raw material purity ≥ 99.5%, conforming to USP standards.

Chirality control : S-configuration optical purity ≥ 99.8%

Excellent stability : Purity remains above 97% after 6 months of accelerated testing.

✅Global supply assurance :

Cold chain logistics : -20℃ cold chain transportation throughout the entire process to ensure product stability.

Multi-warehouse delivery : Regional warehouses are established in China, Europe, America, and the Asia-Pacific region, ensuring delivery within 7 days.

Customs clearance support : Professional document preparation ensures smooth customs clearance worldwide.
