IGF1-LR3:
Dosage, Benefits,
and Research Explained
IGF-1 LR3 (Insulin-Like Growth Factor-1 Long R3) is a potent anabolic peptide that plays a crucial role in muscle growth, fat loss, and recovery. It is a modified version of IGF-1 with an extended half-life, making it significantly more effective at stimulating muscle hypertrophy and recovery.
Unlike GH-releasing peptides (Ipamorelin, CJC-1295, Tesamorelin), which stimulate natural GH production, IGF-1 LR3 directly promotes muscle and tissue growth by activating cellular pathways responsible for regeneration.

How It Works
IGF-1 LR3 binds to IGF-1 receptors in muscle tissue, leading to:
✔ Enhanced protein synthesis → Accelerates muscle growth & repair
✔ Increased nutrient absorption → Optimizes muscle recovery & fat metabolism
✔ Boosted satellite cell activation → Supports muscle regeneration & hypertrophy
✔ Improved glucose regulation → Enhances insulin sensitivity & metabolic function
Because IGF-1 LR3 has a longer half-life than regular IGF-1, it remains active in the body for 24+ hours, leading to sustained anabolic effects.
Research-Backed Benefits
1. Muscle Growth & Strength Enhancement
- IGF-1 LR3 stimulates muscle protein synthesis & hypertrophy, leading to faster muscle gains.
- Works synergistically with resistance training to maximize lean muscle development.
2. Fat Loss & Body Recomposition
- Increases fat oxidation by enhancing glucose metabolism & insulin sensitivity.
- Helps preserve lean muscle while reducing body fat levels.
3. Faster Recovery & Injury Healing
- Accelerates tissue repair and reduces muscle soreness after workouts.
- Can speed up recovery from injuries, tendinitis, and joint damage.
4. Anti-Aging & Longevity
- Supports cellular repair & neuroprotection, reducing age-related muscle loss.
- Improves collagen production for joint & skin health.
5. Increased Endurance & Athletic Performance
- IGF-1 LR3 enhances ATP production, leading to greater stamina & endurance.
- Optimizes oxygen utilization & nutrient uptake in muscle tissue.
Conclusion
IGF-1 LR3 is a powerful anabolic peptide that stimulates muscle growth, fat loss, and recovery by mimicking the natural effects of insulin-like growth factor-1. With its longer half-life and high bioavailability, it is one of the most effective peptides for bodybuilders, athletes, and longevity enthusiasts.
Whether used for muscle hypertrophy, metabolic enhancement, or injury recovery, IGF-1 LR3 provides remarkable results when combined with proper training and nutrition.

How does IGF-1 LR3 differ from regular IGF-1?
How does IGF-1 LR3 differ from regular IGF-1?
How long does it take to see results?
- Muscle growth & strength: Within 2-4 weeks.
- Fat loss & body recomposition: Noticeable in 4-6 weeks.
- Recovery & healing benefits: Within 2-4 weeks of consistent use.
Are there any side effects?
IGF-1 LR3 is generally well-tolerated, but possible mild side effects include:
✔ Temporary water retention
✔ Mild hypoglycemia (low blood sugar)
✔ Joint stiffness (due to increased muscle growth rate)
Tip: To minimize hypoglycemia, consume a balanced meal with protein & carbs post-injection.
Can IGF-1 LR3 be stacked with other peptides?
es! Some popular stacks for enhanced effects include:
✔ CJC-1295 + Ipamorelin + IGF-1 LR3 → Maximum muscle growth & fat loss synergy.
✔ BPC-157 + TB-500 + IGF-1 LR3 → For injury healing & tissue repair.
✔ NAD+ + IGF-1 LR3 → For anti-aging & longevity benefits.
