IGF1 – LR3 – 1mg

IGF‑1 LR3 (Long Arg3 IGF‑1) is a synthetic, extended‑acting analogue of insulin‑like growth factor‑1, supplied as a high‑purity lyophilised peptide for controlled laboratory research. Its modified structure — including the substitution of arginine at position 3 and an extended N‑terminal sequence — provides enhanced stability and reduced affinity for IGF‑binding proteins, allowing researchers to explore prolonged IGF‑1 receptor activation.

IGF‑1 LR3 is widely used in scientific environments investigating cellular growth pathways, nutrient signalling, anabolic biochemical cascades, and comparative IGF analogue behaviour.
