Substance: Insulin-like Growth Factor 1, Long R3 Injection

Action of the Drug

IGF-1 LR3 is a long-acting variant of IGF-1 that promotes sustained muscle growth, enhances protein synthesis, and improves recovery. Its extended half-life allows prolonged anabolic activity and more effective hypertrophy.

Use in Sports

For athletes, IGF-1 LR3 1 mg supports lean muscle gains, faster recovery, and improved strength performance. Ideal for bulking phases and high-intensity training cycles.

Period of Drug Withdrawal

IGF-1 LR3 has a longer half-life compared to standard IGF-1, maintaining effects for up to 20 hours. Complete clearance occurs within a day after the last dose.

Rate of Suppression of Natural Testosterone Production

IGF-1 LR3 does not suppress natural testosterone production, making it safe to use alongside anabolic compounds or other peptides.

What Should Be Used During and After Use

During use:

• Follow high-protein nutrition to support muscle growth
• Stay hydrated and track training performance
• Focus on resistance and hypertrophy training

After use:

• Maintain balanced nutrition and progressive training
