Form

Lyophilized Powder

CAS Number

946870-92-4

Storage

-20°C, desiccated

Overview

IGF-1 LR3 is a recombinant analog of insulin-like growth factor-1 with an arginine substitution at position 3 and a 13-amino acid N-terminal extension. These modifications reduce IGF-binding protein affinity, extending its half-life to approximately 20–30 hours. Used in research on muscle hypertrophy, recovery, and anabolic signaling.

Research Applications

Muscle hypertrophy and anabolic signaling

Recovery and tissue repair

GH/IGF-1 axis research

Lean body mass optimization

Anti-aging and longevity protocols
