IGF-1 LR3, explained simply
A synthetic IGF-1 analogue designed to bind less strongly to certain IGF-binding proteins.
Research area
Tissue growth, metabolism and IGF-1 receptor signalling
How it works
Structural changes alter its binding to carrier proteins and systemic exposure relative to native IGF-1.
Why it matters
The profile shows why findings for natural IGF-1 or related medicines are not automatically evidence for LR3.
What has been observed
Research on the IGF-1 family discusses anabolic and metabolic effects but combines analogue research with clinical data on different compounds.
Effects and points to consider
Extrapolating between molecules needs care; interference with blood-glucose regulation is clinically relevant.
Reported data
