What is MYOSIN (YK-11) by Helixx Online?
MYOSIN by Helixx Online features YK-11 — a powerful SARM and partial myostatin inhibitor. YK-11 is known for unlocking new levels of muscle growth by suppressing the protein myostatin, which normally limits muscle development. This makes it one of the most potent compounds in the SARM category, often compared to low-dose anabolic steroids in strength and results.
Unlike traditional SARMs, YK-11 also activates follistatin pathways, leading to enhanced hypertrophy and strength output. MYOSIN is best used during lean bulking or high-intensity recomposition cycles where maximizing lean tissue with minimal water retention is the goal.
Benefits of YK-11 (MYOSIN)
- Inhibits myostatin, allowing muscle growth beyond genetic limits
- Promotes lean mass development without bloating
- Increases muscle hardness, density, and strength
- Highly anabolic with minimal estrogenic activity
- Stacks well with bulking or recomp SARMs for serious growth

Common Questions About MYOSIN (YK-11)
Is MYOSIN safe for first-time users?
Due to its strong anabolic profile and partial steroid-like mechanism, MYOSIN is better suited for intermediate users or those experienced with SARMs or mild prohormones.
Does YK-11 cause hair loss?
It may elevate DHT levels, so users prone to androgenic side effects should monitor scalp health. Consider stacking with DHT blockers if sensitive.
Can women use YK-11?
Not recommended for women due to its strong androgenic potential. Female-friendly alternatives include Ostarine (MK-2866) or SR9009.
Does it require on-cycle support?
Support supplements like NAC and omega-3s are recommended. Bloodwork is encouraged before and after cycle to track liver enzymes and hormone levels.
