YK-11 by Ultima Pharmaceuticals

Brand: Ultima Pharmaceuticals

Substance: Myostatin

Action of the Drug

YK-11 is a selective myostatin inhibitor that enhances muscle growth by suppressing myostatin levels, increasing follistatin production, and promoting rapid lean mass gains.

Use in Sports

It is ideal for bodybuilders and athletes looking to maximize muscle growth, strength, and overall physique in bulking phases or high-intensity training cycles.

Period of Drug Withdrawal

YK-11 has a half-life of approximately 12–16 hours, with full elimination occurring within 2–3 days after the last dose.

Rate of Suppression of Natural Testosterone Production

YK-11 may moderately suppress natural testosterone; proper PCT is recommended to restore hormonal balance after the cycle.

What Should Be Used During and After Use

During use:

• Support supplements for liver and joint health
• Maintain a nutrient-rich diet and consistent training

After use:

• Post Cycle Therapy (PCT) to restore testosterone
• Recovery supplements for optimal muscle maintenance

Combinations with Other Anabolic and Androgenic Drugs

YK-11 can be stacked with SARMs like Ligandrol or Ostarine for enhanced muscle mass and strength results.

Possible Side Effects and How to Avoid Them

• Testosterone suppression – manage with proper PCT
• Mild fatigue or headaches – dose adjustment may help
• Joint strain – maintain proper training and supplementation
