Collection: Buy YK11 | Myostatin Inhibitor

We are leading UK suppliers of the research chemical YK-11, offering a wide range of the best YK-11 brands and stacks available in the UK. YK-11 is a unique selective androgen receptor modulator (SARM) that also acts as a myostatin inhibitor, promoting exceptional muscle growth. By inhibiting myostatin, a protein that limits muscle development, YK-11 supports greater muscle gains than traditional SARMs.

Research indicates YK-11 provides accelerated muscle growth, increased strength, reduced body fat, enhanced muscle hardness, improved bone density, faster recovery, and better overall body composition. YK-11 is non-aromatizing, meaning it does not convert to estrogen, and generally requires minimal post-cycle therapy (PCT) compared to anabolic steroids.
