Myogenesis, follistatin upregulation, and advanced selective androgen receptor modulator (SARM) research laboratories consistently rely on our YK-11 capsules (Myostine / Next LVL Muscle) as a convenient, precisely dosed research format. Each capsule contains a standardized amount of YK-11, a steroidal SARM renowned for its dual androgen receptor partial agonism and unique myostatin-inhibiting properties via follistatin induction, supplied exclusively for controlled in vitro, pharmacological, muscle cell differentiation, follistatin/myostatin pathway, androgen signaling, and analytical investigations.
Laboratory-Grade Purity & Third-Party Verification
Our YK-11 capsules are formulated with ≥98% pure active compound (often ≥99%), confirmed through orthogonal analytical methods including HPLC, LC-MS/MS, GC-MS, and NMR spectroscopy. Independent third-party testing provides full Certificates of Analysis (CoA) for every batch, verifying chemical identity, exact potency per capsule, residual solvent levels, heavy metal screening, microbial purity, and absence of degradation products or contaminants. This stringent quality protocol ensures batch-to-batch consistency and clean, reproducible results in androgen receptor binding assays, myoblast proliferation/differentiation studies, follistatin gene expression analysis, myostatin pathway inhibition experiments, and reference standard preparation.
As a DHT-derived steroidal SARM, YK-11 stands out in preclinical models for strong anabolic effects in muscle tissue combined with potent follistatin upregulation and myostatin suppression — mechanisms that distinguish it from conventional non-steroidal SARMs and position it as a key reagent for studying enhanced myotube hypertrophy, muscle growth beyond genetic limits, and synergistic anabolic pathways.

Why Researchers Prefer YK-11 Capsules
The capsule format delivers clear advantages for:
- Precise, repeatable dosing without powder weighing variability
- Efficient chronic administration or dose-response protocols in myogenesis studies
- Reduced handling exposure in controlled laboratory settings
- Direct comparison of pre-dosed myostatin-inhibiting compounds in analytical workflows
YK-11 remains a flagship compound for investigating the convergence of androgen receptor activation and myostatin/follistatin signaling, enabling research into amplified muscle cell growth, differentiation, and hypertrophy potential.
“The reliable dosing and exceptional purity of these YK-11 capsules produced strong, dose-dependent follistatin increases and impressive myotube hypertrophy in our myostatin blockade assays – outstanding reagent.” – Muscle Cell Biology & Anabolic Pathway Research Group
