IGF-1 LR3

IGF-1 LR3 (Insulin-like Growth Factor-1 Long R3) is a synthetic analogue of IGF-1 that has been modified by extending its amino acid chain, resulting in reduced binding to IGF-binding proteins and a significantly longer half-life compared to native IGF-1. This modification enhances its stability and prolongs its biological activity in experimental systems.

In scientific research, IGF-1 LR3 is studied for its potent effects on cellular growth, proliferation, and differentiation. It plays a key role in anabolic signaling pathways, particularly those involved in muscle tissue growth, protein synthesis, and tissue regeneration. Researchers also investigate its influence on glucose metabolism and its interaction with growth hormone–mediated pathways.

IGF-1 LR3 is primarily used in laboratory and preclinical studies to better understand growth factor signaling, muscle hypertrophy mechanisms, and regenerative biology, as well as its broader effects on cellular repair and metabolic regulation.
