Selective Androgen Receptor Modulator
The one SARM that doesn’t just occupy the androgen receptor it shuts down the protein that puts a ceiling on muscle growth in the first place. Built for researchers pushing past the genetic limit.

Built For Output
01 — Lean Mass Accrual
Supports muscle tissue development beyond what androgen receptor activation alone accounts for.
02 — Bone Density
Androgen receptor activity in skeletal tissue is linked to structural bone strength.
03 — Strength Output
Studied for gains in strength and endurance alongside mass, not instead of it.
04 — Tissue Retention
Myostatin suppression is studied for its role in preserving existing muscle tissue.
Two Pathways, One Capsule
Most SARMs do one thing: bind the androgen receptor in muscle and bone tissue and stop there. YK11 does that too but it’s also studied as a myostatin inhibitor, targeting the protein whose entire job is to cap how much muscle the body is allowed to build.
Suppress that brake, and the ceiling most training and diet protocols eventually hit starts to move. That’s the distinction researchers are actually studying YK11 for not incremental gain, but a second growth pathway most compounds in this class don’t touch at all.
A — Androgen Receptor Binding
Selective activation in muscle and bone tissue, engineered to minimize off-target activity.
B — Myostatin Suppression
Reduces the signal that limits new muscle tissue formation.
C — Compound Effect
Two independent growth pathways engaged by a single compound, at a fixed 10mg dose.
Compound FAQ
What is YK11?
A Selective Androgen Receptor Modulator that also inhibits myostatin, the protein that limits how much muscle the body builds. Suppressing it is studied as a route to growth beyond typical genetic constraints.
How is it different from other SARMs?
Most SARMs stop at androgen receptor binding. YK11 is studied for a second, separate mechanism myostatin inhibition that most other compounds in this class don’t engage at all.
What’s actually in the capsule?
10mg of YK11 and 5mg of black pepper fruit extract (Piper nigrum) per capsule, included to support absorption. 60 capsules per container.
How should it be stored?
Below 30°C, away from direct light. Do not freeze.
