IGF-1 LR3 0.1mg / 1mg – Int | Long-Acting Peptide for Muscle Growth & Fat Loss
💥 IGF-1 LR3 0.1mg / 1mg – Int | Extended-Action Muscle Growth Peptide
IGF-1 LR3 (Long Arg3 IGF-1) is one of the most powerful muscle-building peptides in the performance enhancement world. Available in 0.1mg and 1mg vials, this international-grade version delivers prolonged anabolic effects, promotes lean mass, and accelerates muscle recovery post-training.
Unlike standard IGF-1, LR3 features a longer half-life (~20–30 hours) and greater receptor affinity, giving users continuous growth stimulation throughout the day.

⚙️ How IGF-1 LR3 Works
IGF-1 LR3 is a modified version of natural IGF-1, altered to resist deactivation by IGF-binding proteins. This results in:
- Enhanced stability and duration in the bloodstream
- Increased uptake of amino acids into muscle cells
- Stimulation of hyperplasia (growth of new muscle fibers)
- Improved fat utilization and muscle preservation
💪 Key Benefits
- 🚀 Builds lean muscle and supports recovery
- 📉 Accelerates fat loss and nutrient partitioning
- 🧬 Promotes hyperplasia and cellular regeneration
- 🩹 Speeds up injury healing and joint recovery
- 🔄 Improves insulin sensitivity and nutrient uptake
- 🧠 Supports cognitive and anti-aging benefits
📋 Suggested Dosage Protocol
| Goal | Dosage | Timing | Duration |
|---|---|---|---|
| Muscle building | 40–80mcg | Post-workout (IM/SubQ) | 4–6 weeks |
| Fat loss / Recomp | 30–50mcg | AM or post-workout | 4–8 weeks |
| Healing / Recovery | 25–40mcg | 1x–2x daily | 2–4 weeks |
| Stack support | 50–80mcg | With GH, DES, or peptides | 6–8 weeks |
- Cycle responsibly: 5 days on, 2 days off recommended
- Do not exceed 100mcg/day unless under expert guidance
- Combine with clean diet and training for optimal results
⚠️ Potential Side Effects
- Mild water retention
- Temporary hypoglycemia (manage with carbs pre/post dose)
- Joint pain at high doses
- Possible desensitization—cycle breaks recommended
- Not for continuous use without breaks (IGF-1 resistance)
✅ Well-tolerated when used in moderate doses with proper cycling.
