Overview
IGF-1 LR3 peptide (Insulin-like Growth Factor 1 Long R3) is a modified version of human IGF-1 with an extended half-life. Through substitution of arginine for glutamic acid at position 3 and a 13-amino acid N-terminal extension, IGF-1 LR3 demonstrates increased stability and reduced binding to IGF-binding proteins. This makes it a powerful research tool for studying muscle growth, glucose regulation, and cell proliferation in preclinical models.
Compound Breakdown
IGF-1 LR3 (0.1mg / 1mg): Modified insulin-like growth factor analog with extended half-life. Investigated for cellular proliferation, muscle repair, and glucose metabolism studies.
Research Applications
Preclinical research with IGF-1 LR3 peptide has explored:
Muscle Growth and Repair → studied for satellite cell activation, protein synthesis, and hypertrophy models.
Cellular Proliferation → investigated for tissue regeneration and repair processes.
Glucose Regulation → studied for insulin-like effects on glucose uptake and metabolism.
Neuroprotection → explored for potential influence on neuronal survival and repair.
Comparative Studies → evaluated against native IGF-1 for stability, receptor affinity, and bioavailability in research models.
Related Categories
IGF-1 LR3 is part of the Muscle & Physique category. It is sometimes studied alongside Tesamorelin and Ipamorelin in anabolic and metabolic research models.
