Dragon Pharma YK 11 is a powerful selective androgen receptor modulator (SARM) that acts as a myostatin inhibitor, making it highly effective for advanced muscle building, recomposition, and physique enhancement. Each tablet contains 10 mg of pure YK-11, backed by scientific research for its unique mechanism and potential benefits.
YK 11 is widely recognized among elite athletes and bodybuilders due to its dual-action mechanism: not only does it bind to androgen receptors, but it also suppresses myostatin, a protein that inhibits muscle growth. This makes it ideal for users seeking to break through natural muscle-building limits.
Unlike other SARMs, YK 11 is a partial androgen receptor agonist and also increases follistatin expression. Follistatin blocks myostatin, resulting in unrestricted muscle fiber development. This makes it a favorite for experienced users aiming for a dry, dense, competition-ready look.
Beginner and intermediate users often run YK 11 at doses between 10–15 mg/day over a 6 to 8-week cycle. Due to mild androgenic properties, some suppression may occur—post-cycle therapy is advised.
YK 11 synergizes well with other SARMs like MK-2866 (Ostarine) or S-23 for advanced cutting stacks. For those focused on lean mass, pairing it with MK-677 (Ibutamoren) offers significant benefits in recovery and growth hormone upregulation.
Our latest batch was tested on 2025-04-18, verifying the presence of 10.06 mg YK-11 per tablet. See results below:
Although YK 11 does not aromatize, it can still cause suppression. Many users choose to include Clomid or Nolvadex during their recovery phase. Depending on cycle duration and dose, 3–4 weeks of PCT may be sufficient.
For those seeking advanced muscle-building support, Dragon Pharma's YK 11 delivers unmatched quality and purity. Combine it with our premium stacks or cycle options to push beyond genetic limitations.
YK 11 is used for building lean muscle, increasing strength, and enhancing muscle hardness. It's especially popular during recomp or dry bulking phases.
Yes, YK 11 can cause suppression of natural testosterone, so a short PCT cycle using Clomid or Nolvadex is often recommended after use.
Absolutely. YK 11 stacks well with MK-2866, MK-677, or S-23 for enhanced lean mass or cutting results.
YK 11 may cause testosterone suppression, mild aggression, or liver strain at high doses. Monitoring and moderate dosing are recommended.
