What is IGF-1 LR3?
IGF-1 LR3 (Insulin-like Growth Factor 1 Long Arg3) is a synthetic peptide analogue of human IGF-1, modified to have a significantly longer half-life and enhanced biological stability. The substitution of arginine at position 3 and the extension of the amino acid chain contribute to a half-life of approximately 20–30 hours, compared to less than 30 minutes for natural IGF-1.
IGF-1 LR3 is widely studied in preclinical environments for its potential roles in cell growth, muscle development, and tissue regeneration. Researchers often explore its effects on protein synthesis, recovery processes, and anabolic signalling pathways in laboratory models.
