YK11

Myostatin Inhibitor & Androgen Receptor Modulator

Nordic Labs YK11 is an advanced research compound that combines the selective targeting of androgen receptors with unique myostatin inhibition properties to explore muscle growth and anabolic signalling pathways. Known for its distinctive dual action, YK11 is widely studied in cellular and laboratory settings for effects on lean muscle development and strength potential.

Main Benefits of Nordic Labs YK11

• May support lean muscle mass research and growth pathways
• Acts as a partial androgen receptor agonist
• Encourages expression of follistatin, a myostatin inhibitor
• Potential to enhance strength and anabolic signalling
• Useful for studies on muscle cell differentiation

YK11’s unique activity makes it a compound of interest where research into muscle anabolism, myostatin regulation, and androgen receptor signalling is being explored. 

How YK11 Works

YK11 is classed among selective androgen receptor modulators (SARMs) with additional myostatin inhibition activity. It binds selectively to androgen receptors, triggering anabolic signalling in muscle tissues while also increasing production of follistatin — a natural protein that inhibits myostatin, which can otherwise limit muscle growth. This dual action is often the reason YK11 is studied alongside other SARMs and performance pathways. 

Because of this mechanism, YK11 is distinct from traditional non‑steroidal SARMs and is researched for its potential to support enhanced anabolic responses in laboratory models.

Frequently Asked Questions

What is Nordic Labs YK11?

Nordic Labs YK11 is a research compound that combines selective androgen receptor modulation with myostatin inhibition potential, making it a compound of interest in studies focused on muscle growth, strength signalling, and anabolic pathways. 

How does YK11 differ from other SARMs?

Unlike many non‑steroidal SARMs, YK11 has a unique steroidal backbone and may increase follistatin expression — a protein that inhibits myostatin, which limits muscle growth. This gives it a different research profile compared with traditional SARMs. 

Can YK11 help support muscle research?

In laboratory studies, YK11 may influence pathways linked to muscle cell differentiation and anabolic signalling, making it a valuable tool for research into lean mass biology. 

Is this product approved for human use?

No — YK11 is supplied for research purposes only and should not be used for human or animal consumption. Always adhere to applicable legal and safety requirements.
