What the research examined
IGF-1 literature examines growth-related signaling and skeletal-muscle biology. One experimental report used gene transfer in a mouse muscle model, while a later review describes broader muscle pathways. Both help explain biological questions about IGF-1.
How to interpret the findings
Evidence involving endogenous IGF-1 or gene transfer is not a direct validation of IGF-1 LR3. A modified analogue requires its own characterization, and a finding in a mouse muscle model cannot establish clinical performance or safety.
