YK-11 SARM 25mg Capsules – Advanced Muscle Growth & Strength Research Compound

YK-11 is a powerful synthetic Selective Androgen Receptor Modulator (SARM) developed for advanced laboratory research into muscle hypertrophy, strength development, lean mass accrual, and myostatin inhibition.

Unlike traditional SARMs, YK-11 is widely studied for its ability to influence myostatin pathways, a biological regulator that limits muscle growth. By modulating this pathway, YK-11 is researched for its potential to dramatically enhance muscle development, improve strength output, and optimise body composition in controlled research environments.

Each capsule delivers 25mg of pharmaceutical-grade YK-11, manufactured to strict purity standards with no fillers or unnecessary additives.

Supplied by MK677 Shop USA, a trusted international research compound distributor.

Key Research Applications

Muscle Hypertrophy Research
Used in studies investigating accelerated muscle growth through myostatin pathway modulation.

Strength & Performance Studies
Supports research into increased power output, force production, and training capacity.

Lean Mass Development
Ideal for analysing skeletal muscle density, lean body mass retention, and recomposition models.

Bone Density Research
Examines androgen receptor activity in bone tissue and skeletal integrity.

Selective Androgen Activity
Designed for tissue-selective androgen receptor interaction with reduced off-target activity.

Post-Cycle Support (Research Protocol)

Due to YK-11’s androgen receptor activity and influence on anabolic signalling, post-cycle hormonal recovery protocols are commonly incorporated into research models to assess endocrine normalisation and baseline restoration.

Dedicated SARMs cycle support compounds are often used to evaluate hormone regulation, lipid health, and systemic recovery following compound exposure.
