Receptor Grade IGF-1 LR3 (1mg)

Receptor Grade IGF-1 LR3 is a potent synthetic analog of human IGF-1 engineered with an 83-amino-acid sequence featuring a 13-amino-acid N-terminal extension and an arginine substitution at position 3, drastically reducing its binding to IGF binding proteins (IGFBPs) and enhancing its interaction with the IGF-1 receptor. With a molecular weight of 9117.5 g/mol, it is approximately 2.5-3 times more potent than regular IGF-1 in promoting anabolic activities, making it a powerful tool for research in cellular proliferation, differentiation, and survival. It potently counteracts myostatin’s suppressive effects in muscle research, improves glucose uptake via PI3K/Akt pathways, and is valuable for studying muscle wasting, diabetes, and tissue repair.
