YK-11 10mg/cap 60 caps

$125.00

YK-11 is a synthetic selective androgen receptor modulator (SARM) with partial myostatin-inhibiting properties. It’s unique because, unlike most SARMs, it not only binds to androgen receptors to promote muscle growth but also reduces myostatin, a protein that limits muscle development. This makes it highly appealing for those looking to gain significant lean mass in a short period. While effective, it is also considered one of the more potent and potentially risky SARMs due to its limited research and strong anabolic activity.

How It Works

YK-11 binds to androgen receptors in muscle and bone tissue, triggering anabolic signals that enhance protein synthesis and muscle growth. In addition, it promotes the expression of follistatin, which suppresses myostatin — removing a “growth cap” on muscles. The result can be rapid hypertrophy and strength gains. However, because YK-11 has steroid-like properties, it may cause more pronounced suppression of natural testosterone compared to other SARMs.

How to Use It

  • Dosage: Commonly 5–10 mg daily for men; women typically stay lower at 2–5 mg daily. Beginners often start on the low end to assess tolerance.

  • Frequency: Due to its short half-life (~6–10 hours), split dosing (morning & evening) can help maintain stable levels.

  • Cycle Length: Usually 4–8 weeks to balance results with safety. Longer cycles increase the risk of side effects.

  • Stacking: Often stacked with SARMs like LGD-4033 for bulk or Cardarine for endurance. Can be combined with testosterone in advanced cycles but increases suppression risk.

  • Post-Cycle Therapy (PCT): Strongly recommended due to significant suppression. Common PCT agents include Nolvadex or Clomid for 4–6 weeks.

  • Precautions: Avoid high doses early, monitor liver health, and be aware of potential androgenic side effects.
