Long-Arg3 IGF-1 — a recombinant analogue of insulin-like growth factor 1 engineered for an extended half-life. An N-terminal extension and Arg3 substitution reduce IGF-binding-protein affinity, keeping it active far longer than native IGF-1 in research models. Studied for its role in cellular proliferation, hypertrophy, and nutrient partitioning.
