IGF-1 LR3 – Product Overview
IGF-1 LR3 (Insulin-like Growth Factor 1 Long R3) is a synthetic analog of naturally occurring IGF-1, engineered for greater metabolic stability and biological effectiveness. Each vial provides 0.1mg of IGF-1 LR3, delivering a formulation designed for advanced research into muscle growth, cellular regeneration, and tissue repair.
Biology of IGF-1 LR3
IGF-1 is a naturally occurring hormone similar in structure to insulin. It plays a key role in growth, development, and cellular health. IGF-1 LR3 incorporates structural modifications— including an extended 13-amino-acid sequence and an amino acid substitution at position 3—preventing binding to IGF-binding proteins (IGFBPs). This enhances its biological activity and significantly prolongs its functional half-life.
Mechanism of Action
- IGF-1 Receptor Activation: IGF-1 LR3 binds to the IGF-1 receptor, initiating intracellular signaling pathways involved in growth and repair.
- Protein Synthesis Support: Promotes enhanced nutrient uptake and supports anabolic activity in muscle and connective tissue.
- Cell Survival Pathways: Helps inhibit apoptosis and encourages regeneration in targeted tissue types.
Research Areas & Potential Applications
Muscle Growth and Recovery
IGF-1 LR3 is widely studied in performance and hypertrophy research due to its potential to support muscle-cell proliferation, nutrient uptake, and tissue repair.
Regenerative and Anti-Aging Studies
Research suggests IGF-1 LR3 may influence age-related cellular decline, muscle wasting, and tissue regeneration, making it a focus of ongoing anti-aging investigations.
Neurological Function
IGF-1 signaling has been studied for its potential roles in supporting nerve regeneration and protecting neurological tissues.
Bone & Connective Tissue Health
IGF-1 pathways are integral to bone remodeling and collagen production, with IGF-1 LR3 often explored in studies involving skeletal integrity and injury recovery.
Product Composition
- Quantity: 1 vial
- Strength: 0.1mg IGF-1 LR3 per vial
