Uni Mix II (YK11-RAD-MK)
Uni Mix II (YK11-RAD-MK).YK-11 is one of the most unique compounds in the world of SARMs — although technically, it isn’t a true SARM. It’s often classified as a myostatin inhibitor with partial SARM activity, meaning it not only stimulates muscle growth by binding to androgen receptors but also limits the body’s natural ability to suppress growth through myostatin.

Myostatin is a protein that regulates muscle cell growth — in essence, it tells your body when to stop building muscle. YK-11 works by increasing follistatin, a natural antagonist to myostatin, allowing muscle cells to continue growing beyond what your body would normally permit.
This mechanism makes YK-11 incredibly powerful for:
→ Increasing muscle fiber size and density
→ Improving muscle differentiation at the cellular level
→ Gaining lean mass without significant water retention
→ Producing a hard, dry look when paired with a clean diet
YK-11 increases follistatin expression, which inhibits myostatin, allowing for accelerated skeletal muscle hypertrophy
YK-11 is also methylated (17-alpha-alkylated), which gives it excellent oral bioavailability — but also means it can place some strain on the liver. Unlike most SARMs, its hybrid classification and myostatin-suppressing action put it in a league of its own. wiki give more information on it.
