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.
In short, studies suggest it combats muscle loss caused by age, osteoporosis, disease, and building muscle and bone.
This targeted gene interaction gives YK11 powerful anabolic potential, making it a popular choice for those seeking advanced muscle-building and strength-enhancing results.
