IGF-LR3
Long-acting insulin-like growth factor — muscle growth and recovery
Aperçu
IGF-LR3 is a modified version of insulin-like growth factor 1 (IGF-1) with an extended half-life for sustained muscle-building effects.
Key Information
Mechanism
Binds to IGF-1 receptors to promote muscle protein synthesis, satellite cell activation, and muscle hypertrophy. LR3 modification extends half-life to ~20 hours.
Benefits
- Muscle hypertrophy
- Enhanced recovery
- Satellite cell activation
- Extended half-life (LR3)
Side Effects
- Hypoglycemia risk
- Organ growth concerns at high doses
- Injection site pain
Contraindications
- Active cancer
- Diabetes (hypoglycemia risk)
Evidence Summary
Studies show significant muscle hypertrophy and improved recovery compared to GH.
Research
Studies show significant muscle hypertrophy and improved recovery. Often compared to growth hormone effects.
Safety
Potential for hypoglycemia. Organ growth concerns at high doses.
Legal Status
Not FDA-approved. Available as research chemical.

Rating Breakdown
Avis
IGF-LR3 is the most potent muscle-building peptide I've used. Hypertrophy is noticeable within 2 weeks. Recovery between workouts is dramatically faster. The extended half-life of LR3 makes it superior to regular IGF-1. Handle with respect - this is powerful.
IGF-LR3 delivers on muscle growth. Pump is incredible, recovery is fast. The LR3 variant lasts 20-30 hours which is much better than DES. Need to be careful with blood sugar - can cause hypoglycemia. Not for beginners.
