YK11 is a potent SARM known for its unique mechanism as a partial androgen receptor agonist. It promotes muscle growth and bone development by increasing follistatin (FST) levels, which suppresses myostatin (GDF8) - a protein that limits muscle growth. This targeted gene interaction gives YK11 powerful anabolic potential, making it a popular choice for those seeking advanced muscle-building and strength-enhancing results.
In short, studies suggest they combat muscle loss caused by age, osteoporosis, disease, and building muscle and bone.
