Description

IGF-1 LR3 (Long Arg3 Insulin-like Growth Factor-1) is a research-use-only synthetic peptide analog of endogenous human IGF-1, modified by substituting a glutamic acid with an arginine at position 3 and adding a 13-amino-acid extension at the N-terminus. In laboratory environments, it is highly utilized to investigate mechanisms of cellular proliferation, skeletal muscle tissue hypertrophy, and protein synthesis activation pathways. Researchers favor this specific analog due to its drastically reduced affinity for insulin-like growth factor-binding proteins (IGFBPs), allowing it to remain active significantly longer and bypass endogenous regulatory inhibitors to study prolonged receptor activation. It is intended strictly for laboratory research and should not be used for human consumption, medical treatment, or diagnostic purposes.

Research Reference Amounts 20 mcg — 50 mcg

Research Titration Reference These reference amounts are commonly organized in a daily administration schedule, typically evaluated post-exercise or post-stimulation in cellular and animal fatigue models to observe targeted tissue recovery cascades, depending on the study design and laboratory protocol.
