What is Receptor Grade IGF-1 LR3 and How Does It Function?
Receptor Grade IGF-1 LR3 (Insulin-like Growth Factor-1 Long Arginine 3) is a highly stable, 83-amino-acid synthetic analog of human IGF-1. The molecule is engineered with an addition of a 13-amino-acid N-terminal extension peptide and a structural substitution of Arginine for Glutamic Acid at position 3.
The primary investigative framework for researchers to buy Receptor Grade IGF-1 LR3 centers on its specialized pharmacokinetics:
Reduced IGFBP Affinity: This analog does not bind strongly to Insulin-like Growth Factor Binding Proteins (IGFBPs), which normally deactivate native growth factors in the bloodstream.
Extended Research Half-Life: By evading binding proteins, the free peptide exhibits an extended laboratory half-life of 20 to 30 hours, compared to only 20 minutes for standard IGF-1.
Enhanced Receptor Activation: The unbound compound continuously stimulates the Type I IGF receptor, optimizing studies on cellular proliferation, tissue maintenance, and metabolic signaling.
