Overview
YK-11 is often described as a "high potency" compound that may both interact with androgen receptors and inhibit myostatin, a protein involved in limiting muscle growth. It's treated as experimental because the strongest evidence is still preclinical, and side effects - including liver and hormone-related risks - have been reported by users.
Plain-language summary
YK-11 is often described as a "high potency" compound that may both interact with androgen receptors and inhibit myostatin, a protein involved in limiting muscle growth. It's treated as experimental because the strongest evidence is still preclinical, and side effects - including liver and hormone-related risks - have been reported by users.
Administration Routes
- Oral
Also known as
Mechanisms
Steroid derivative with SARM-like properties - binds to androgen receptors and inhibits myostatin. Double mechanism: turns on muscle building AND removes the natural limit on how big muscles can get.
Detailed mechanism
Steroid derivative with SARM-like properties - binds to androgen receptors and inhibits myostatin. Selectively binds to androgen receptors in muscle and bone tissue while minimizing effects on other organs, promoting anabolic effects with reduced side effects compared to traditional steroids.
Safety
Side effects
- Testosterone suppression
- Liver stress (risk may increase with oral anabolic compounds)
- Hair loss (if prone)
- Joint pain
- Sleep disruption
- Mood or behavioral changes
Reported benefits
- Blocks myostatin (muscle growth limiter)
- Binds to androgen receptors
- Significant muscle mass gains
- Increased strength
Safety profile
Limited human safety data. If you choose to research this topic, treat it as experimental and avoid self-medication - seek medical guidance when relevant.
Clinical trials
Preclinical studies reported. Human studies are limited.
