YK-11 - Spectre Labs

Unlike most SARMs, YK-11 exhibits a dual mechanism by acting as both a myostatin inhibitor and a potent androgen receptor agonist. This unique combination allows it to rapidly enhance muscle growth and strength by increasing follistatin levels, effectively reducing myostatin’s inhibitory effect on muscle development. Structurally, it resembles DHT, delivering intense anabolic effects with minimal water retention. However, its suppressive nature can significantly impact natural testosterone production, necessitating post-cycle therapy to restore hormonal balance and prevent side effects .
