About YK 11
YK-11 is a synthetic steroidal selective androgen receptor modulator (SARM) analog that also functions as a potent myostatin inhibitor. It is structurally related to dihydrotestosterone (DHT) and has demonstrated the ability to increase muscle growth by upregulating follistatin expression, which inhibits myostatin — a negative regulator of muscle mass. Research suggests YK-11 combines anabolic signaling with regulatory effects on myogenesis and muscular hypertrophy.
Research Studies
▪ Muscle Growth & Follistatin Modulation
▪ Anabolic Signaling Without Estrogenic Activity
- Binds to androgen receptors without strong conversion to estrogen
- Promotes lean mass accrual in preclinical models
▪ Skeletal Muscle Development
- Studied in models focused on sarcopenia, muscle wasting, and performance research
