IGF-1 LR3

Peptide Profile

IGF-1 LR3 (Insulin-Like Growth Factor-1 Long R3) is a synthetic, extended analogue of human IGF-1 engineered for enhanced stability and receptor binding duration.
This recombinant peptide differs from native IGF-1 by a 13-amino-acid extension at the N-terminus, significantly increasing its half-life and bioavailability for laboratory applications.

Researchers value IGF-1 LR3 for its capacity to activate anabolic and regenerative signaling cascades, particularly through the PI3K-Akt and MAPK pathways that regulate cell growth, protein synthesis, and tissue repair.
It is frequently examined in studies focused on muscle cell proliferation, recovery dynamics, and metabolic adaptation, often alongside compounds such as HGH, CJC-1295, and GHRPs for broader growth-axis exploration.
