Looking to boost your muscle growth like never before? Discover YK-11, also known as Myostine — a potent SARM-like compound known for its ability to inhibit myostatin and significantly accelerate lean muscle development. Ideal for researchers exploring next-level performance support.
Manufactured with 99% purity and now available via Buffelotis.com, our YK-11 capsules offer quality you can trust, delivered fast and discreetly.
YK-11 is a Selective Androgen Receptor Modulator (SARM) with anabolic steroid-like properties, designed to inhibit the protein myostatin, which naturally limits muscle growth. By blocking myostatin activity, YK-11 removes this cap — potentially resulting in faster muscle gains, improved strength, and shorter recovery times.
Though it behaves similarly to SARMs, YK-11 is considered more advanced due to its dual mechanism: targeting androgen receptors and modulating gene expression related to muscle growth.
