IGF-1 LR3
IGF-1 LR3 (Insulin-Like Growth Factor-1 Long Arg3) is a synthetic, long-acting analog of human IGF-1. It plays a key role in cell growth, repair, and regeneration, with a modified structure that greatly extends its half-life and potency compared to natural IGF-1.

Research Overview
Key Benefits
- Muscle Growth & Repair
- Stimulates muscle cell hyperplasia (creation of new muscle cells) and hypertrophy (growth of existing cells).
- Enhances recovery after intense training or injury.
- Improved Recovery & Performance
- Accelerates tissue repair in muscles, tendons, ligaments, and nerves.
- Supports faster bounce-back between training sessions.
- Fat Metabolism
- Promotes fat utilization for energy, potentially improving body composition.
- Anti-Aging & Cellular Health
- Supports collagen production and tissue regeneration.
- May help maintain organ and skin health.
- Bone & Joint Support
- Stimulates bone growth and repair, aiding skeletal strength.
Why It’s Effective
- The “LR3” modification replaces arginine at position 3 and adds a 13-amino-acid extension, making it resistant to binding proteins that normally limit IGF-1’s activity.
- This gives IGF-1 LR3 a half-life of ~20–30 hours versus minutes for native IGF-1, allowing greater systemic effects.
Important Notes
- Typically used in research via subcutaneous or intramuscular injection.
- Not FDA-approved for human medical use; sold for research purposes only.
- Most evidence is from animal studies, with limited controlled human data.
- Potential side effects: hypoglycemia, joint pain, or soft tissue swelling.
