IGF-1 LR3 (Long R3 IGF-1) is a synthetic analogue of insulin-like growth factor 1. It carries an arginine substitution at position 3 and a 13-amino-acid N-terminal extension that alter its binding profile to IGF-binding proteins. It is used in laboratory research as a reference compound for IGF-axis studies.
