IGF-1 LR3 1mg – Research Peptide
For Research Use Only – Not for Human Consumption
IGF-1 LR3 (Long Arg3 Insulin-Like Growth Factor-1) is a synthetic peptide analog of human IGF-1. It has been modified to extend its half-life in vitro, allowing for enhanced stability and prolonged activity during laboratory testing. The substitution of arginine at position 3 and removal of the first three amino acids in the native IGF-1 sequence make LR3 more resistant to binding proteins, thereby increasing its bioavailability in research environments.
Researchers value IGF-1 LR3 for its role in studying cellular growth, differentiation, survival pathways, and metabolic functions. It has been widely used in experimental models to explore muscle cell proliferation, neuroprotection, and regenerative mechanisms.
