Description
IGF-1 LR3 (Long R3 Insulin-Like Growth Factor-1) is a modified analog of IGF-1 designed for research involving growth factor signaling pathways. The LR3 modification has been studied for its increased stability and extended biological activity compared to standard IGF-1.
Research areas include:
• Muscle cell growth and repair signaling research
• Protein synthesis pathway studies
• Recovery and regeneration research
• Nutrient uptake and metabolic pathway studies
• Cellular growth and development research
• Body composition and performance research models
IGF-1 LR3 is commonly studied in relation to anabolic signaling, cellular repair mechanisms, and growth hormone–associated pathways.
