YK11 10mgx30tabs
$40.00
- YK-11 binds to ARs in specific tissues, such as muscle and bone, initiating processes that lead to muscle growth and increased bone density.
- Myostatin Inhibition: Myostatin is a protein that naturally limits muscle growth. YK-11 promotes the expression of follistatin, a natural myostatin antagonist, effectively removing a natural "brake" on muscle development. This dual mechanism is what contributes to its high potency in laboratory settings.
