IGF-1 LR3 1mg – Research Grade Peptide

IGF-1 LR3 (Long Arg3 Insulin-like Growth Factor-1) is a synthetic, modified analog of the naturally occurring human Insulin-like Growth Factor-1 (IGF-1). This 83-amino acid peptide features key structural enhancements: a 13-amino acid extension at the N-terminus and an arginine substitution for glutamic acid at position 3. These modifications significantly increase its potency (approximately 3x that of native IGF-1) and extend its half-life to about 20–30 hours, making it a valuable tool for laboratory research into cell proliferation, tissue growth, and metabolic pathways.

Key Research Properties:

• High Purity: >99% (HPLC verified) lyophilized powder.
• Form: 1mg per sterile vial, supplied for reconstitution in research settings.
• Mechanism: Acts as a potent agonist of the IGF-1 receptor with low affinity for IGF-binding proteins (IGFBPs), supporting studies on hyperplasia, protein synthesis, nutrient partitioning, and cellular repair models.

Researchers commonly explore IGF-1 LR3 for its potential roles in:

• Muscle cell proliferation and hypertrophy
• Fat metabolism and nutrient utilization
• Tissue regeneration and recovery processes
• Insulin sensitivity and metabolic signaling pathways
