IGF-1 LR3, also known as Long R3 Insulin-Like Growth Factor 1, is a modified analogue of naturally occurring IGF-1. Researchers developed the compound with structural modifications that influence its interactions with IGF-binding proteins and its biological activity compared with endogenous IGF-1.

It has subsequently become a subject of experimental research examining IGF signaling pathways, cellular growth, differentiation, protein synthesis, and metabolic processes.

IGF-1 LR3 has not been established as an approved treatment for bodybuilding, muscle enhancement, anti-aging, or athletic performance. Human therapeutic use therefore should not be inferred from experimental findings.
