Description
IGF-1 LR3 – 1mg Lyophilised Powder
Cellular Growth Research • Nutrient Partitioning • Performance Pathways
Density Labs IGF-1 LR3 is a high-purity, lyophilised insulin-like growth factor analogue supplied with bacteriostatic water for precise and controlled reconstitution.
IGF-1 LR3 (Long R3 Insulin-Like Growth Factor-1) is a modified analogue of IGF-1 with an extended half-life and reduced binding to IGF-binding proteins. This allows for increased bioavailability and prolonged activity in research environments.
Unlike growth hormone–releasing peptides, IGF-1 LR3 acts directly at the cellular level, promoting pathways associated with cell growth, nutrient uptake, and tissue development. It is widely studied for its role in muscle hypertrophy, recovery, and nutrient partitioning.
Delivered in freeze-dried form for enhanced stability and extended shelf life, this premium kit is designed for laboratories exploring advanced anabolic and cellular performance pathways.
Key Benefits & Research Focus Areas
IGF-1 LR3 is commonly studied for its involvement in:
Cellular Growth & Muscle Development
Promotes cellular proliferation and hypertrophy pathways linked to muscle tissue growth.
Enhanced Nutrient Partitioning
Supports efficient delivery of nutrients into muscle cells, improving anabolic efficiency in research models.
Recovery & Tissue Repair
Accelerates cellular repair processes, supporting recovery-focused research environments.
Protein Synthesis Pathways
Activates pathways involved in protein synthesis and muscle fibre development.
Body Composition Optimisation
Supports lean tissue retention while influencing fat metabolism pathways.
Extended Activity Profile
Modified structure provides a longer duration of action compared to standard IGF-1 peptides.
Performance & Output Research
Studied for its impact on strength, endurance, and overall performance-related pathways.
