Buy YK-11 Powder (Myostine) – High-Purity Steroidal SARM for Muscle Growth Research

Introduction

YK-11 is a gene-selective partial agonist of the androgen receptor (AR) that differs from traditional SARMs by its ability to induce follistatin expression, a protein that inhibits myostatin—a natural negative regulator of muscle growth. This dual action results in enhanced muscle hypertrophy and strength gains, making YK-11 a promising compound for combating muscle wasting diseases and promoting body recomposition.

Chemically, YK-11 has the formula C25H34O6 and a molecular weight of 430.54 g/mol. It acts via selective androgen receptor modulation without inducing the full N/C terminal interaction required for complete AR activation, potentially reducing some androgenic side effects compared to traditional anabolic steroids.

Key Features & Benefits
