YK-11

What is YK-11

YK-11 is a myostatin inhibitor and selective androgen receptor modulator (SARM) being researched for its potential to significantly boost muscle growth beyond genetic limits. It works by inhibiting myostatin, a protein that restricts muscle development, and simultaneously activates androgen receptors. YK-11 is a hybrid compound that acts more aggressively than typical SARMs and is favored for advanced bulking protocols.

Benefits of YK-11

• Potently enhances lean muscle growth
• Inhibits myostatin for unrestricted muscle development
• Increases strength and power output
• May improve muscle density and hardening
• Ideal for advanced bulking or strength stacking  

How to Use YK-11

Previous Research Dosages Used: Typical dosages range from 5mg to 15mg daily over 6–8 weeks. Due to its potency and partial androgenic effects, PCT is highly recommended following use.

Frequently Asked Questions

1. Is YK-11 a SARM or steroid?  
YK-11 is a SARM with steroidal properties. It selectively binds to androgen receptors but has partial androgenic effects.

2. Does YK-11 require a PCT?  
Yes, it is suppressive and should be followed by a post-cycle therapy protocol.

3. Can YK-11 be stacked?  
Yes, it is commonly stacked with LGD-4033 or RAD-140 for maximum size and strength gains.

4. What makes YK-11 different from other SARMs?  
Its myostatin inhibition gives it a unique muscle-building edge, pushing past normal growth limitations.

5. Are there side effects with YK-11?  
Potential side effects may include testosterone suppression and increased aggression. Proper cycle support is advised.
