YK-11 10mg – 50 Tablets
Product Overview
YK-11 is a powerful synthetic compound classified as a Selective Androgen Receptor Modulator (SARM) with a unique steroidal backbone, distinguishing it from traditional SARMs. Acting as a partial agonist of the androgen receptor, YK-11 stands apart due to its potent myostatin-inhibiting properties, making it one of the most sought-after compounds for serious athletes, bodybuilders, and physique-focused researchers.
Each bottle contains 50 oral tablets dosed at 10mg per tablet, lab-tested for purity and consistency.

Benefits & Effects
- Explosive Lean Muscle Growth – YK-11 stimulates follistatin production, a potent inhibitor of myostatin (the protein that limits muscle growth), unlocking gains beyond natural genetic potential.
- Strength & Power Gains – Users report rapid increases in raw strength and training output.
- Muscle Hardening & Density – Produces dry, dense muscle with no water retention, ideal for cutting, recomposition, and contest prep.
- Body Recomposition – Perfect for simultaneous fat loss and lean muscle preservation/growth.
- Bone Health Support – Demonstrates osteogenic activity, supporting stronger bone tissue.
- No Estrogen Conversion – Non-aromatizing, eliminating concerns of bloating, gyno, or estrogenic side effects.
How It Works
YK-11 binds selectively to androgen receptors in muscle and bone tissue, triggering anabolic activity without the widespread side effects of traditional anabolic steroids. Simultaneously, it boosts follistatin levels, which suppresses myostatin — the body’s natural “brake” on muscle growth — allowing for accelerated hypertrophy.
Recommended Usage
- Dosage: 10–15 mg per day
- Cycle Length: 6–8 weeks
- PCT: Post-cycle therapy is strongly recommended (e.g., Clomid or Enclomiphene) due to potential HPG axis suppression.
Stacks Well With
- Cutting: Cardarine (GW-501516), Andarine (S4)
- Bulking: RAD-140, LGD-4033, MK-677
- Recomp: Ostarine (MK-2866)
