What is IGF-1 LR3?

IGF-1 LR3 (Long Arg3 Insulin-like Growth Factor-1) is a synthetic analog of human IGF-1 designed for extended half-life and enhanced bioactivity. This peptide consists of 83 amino acids, with a substitution of arginine at position 3 and a 13-amino acid extension at the N-terminus, which prevents binding to IGF-binding proteins (IGFBPs).

Because of this modification, IGF-1 LR3 remains active in circulation for up to 24–30 hours, making it a valuable research peptide for studying growth, regeneration, and protein synthesis.


How Does IGF-1 LR3 Work in the Body?

IGF-1 LR3 mimics the natural actions of insulin-like growth factor 1, a hormone that mediates many anabolic effects of growth hormone (GH). It binds to IGF-1 receptors in muscle, bone, and connective tissues, stimulating:

  • Protein synthesis for lean tissue growth

  • Cellular differentiation and repair

  • Glucose uptake and nutrient partitioning in muscle cells

By resisting degradation from IGFBPs, IGF-1 LR3 maintains higher activity in circulation, amplifying growth signals and recovery pathways over a longer period.


Key Benefits of IGF-1 LR3

  • Supports lean muscle tissue growth and repair

  • Enhances cellular regeneration and tissue recovery

  • Promotes fat metabolism and improved body composition

  • Facilitates wound healing and anti-aging research models

  • Extends IGF-1 activity duration for consistent anabolic signaling
