IGF-1LR3

IGF-1 LR3 1mg – Premium Long-Acting Insulin-Like Growth Factor-1 Peptide for Muscle Hypertrophy & Recovery Research | Advanced IGF-1 Analogue to Promote Satellite Cell Activation, Lean Muscle Growth & Extended Anabolic Signaling Insights

Drive superior muscle growth and regeneration with IGF-1 LR3 1mg from Ion Peptide, the high-purity, long-acting analogue of Insulin-Like Growth Factor-1 designed for advanced laboratory studies on muscle hypertrophy, satellite cell proliferation, protein synthesis, and tissue repair. With an extended half-life and enhanced potency compared to native IGF-1, IGF-1 LR3 delivers prolonged anabolic signaling directly at the muscle level, making it a powerful research tool for exploring localized and systemic muscle-building pathways, recovery acceleration, and body composition optimization.

Premium Product Overview

IGF-1 LR3 (Long R3 IGF-1) is supplied as a stable lyophilized acetate salt in convenient 1mg vials for easy reconstitution.

This modified 83-amino acid peptide features a substitution of arginine for glutamic acid at position 3 (R3) and a 13-amino acid extension at the N-terminus, dramatically increasing its biological activity and half-life (approximately 20–30 hours vs. native IGF-1’s ~10 minutes). Molecular weight is approximately 9,111 Da. Manufactured at ≥99% purity (third-party HPLC & MS verified), IGF-1 LR3 provides researchers with a highly bioactive, long-acting tool for precise investigations into the IGF-1/PI3K/Akt/mTOR pathway and muscle-specific anabolic responses.

Key Research Benefits of IGF-1 LR3 1mg

• Potent Muscle Hypertrophy: Strongly activates satellite cells, promotes myofiber hyperplasia, and increases muscle cross-sectional area through enhanced protein synthesis.
• Extended Anabolic Signaling: Prolonged half-life allows sustained muscle growth and recovery effects with less frequent dosing compared to standard IGF-1.
• Improved Recovery & Repair: Accelerates healing of damaged muscle tissue, tendons, and ligaments in research models of injury or intense training.
• Enhanced Nutrient Uptake: Boosts glucose and amino acid transport into muscle cells, supporting greater nutrient partitioning and lean mass gains.
• Synergistic Potential: Frequently studied with GH secretagogues (GHRP-2, GHRP-6, Sermorelin) or MGF/PEG-MGF for amplified hypertrophic and regenerative results.

Researchers regard IGF-1 LR3 as the “king of localized muscle growth” peptides due to its superior potency and duration of action for hypertrophy studies.

Quality Assurance & Usage in Research

Sourced exclusively for laboratory research with USA-verified COAs. IGF-1 LR3 1mg reconstitutes easily with bacteriostatic water. The extended half-life supports flexible dosing schedules. Store lyophilized vials at -20°C and reconstituted solutions refrigerated.

Common Research Protocols (for reference only): Typical subcutaneous or intramuscular doses in studied models range from 20–100 mcg per injection, often administered post-workout into target muscle groups or systemically 3–7 days per week. Some protocols use 40–80 mcg daily for 4–6 weeks. Always follow precise reconstitution and institutional guidelines.

Important Research Considerations

IGF-1 LR3 1mg is a potent research chemical intended strictly for laboratory use only. It is significantly more anabolic than native IGF-1 and may carry risks of hypoglycemia or excessive tissue growth if not properly controlled. Common observations include mild injection site reactions or transient blood sugar fluctuations. It is not approved by regulatory agencies for human therapeutic, cosmetic, or performance use. Prioritize proper protocols, biomarker monitoring (muscle mass, IGF-1 levels, glucose), and consult qualified professionals for any application beyond strict lab research.
