IGF-1 LR3

A long-acting analogue of Insulin-Like Growth Factor 1, studied for muscle development, cellular repair, and metabolic effects.

What Is IGF-1 LR3?

What Is IGF-1 LR3?

IGF-1 LR3 is a synthetic variant of Insulin-Like Growth Factor 1 (IGF-1) with an extended half-life due to modifications that reduce binding to IGF binding proteins. IGF-1 is a key signaling molecule involved in growth, cellular repair, and metabolism.

How Does It Work?

IGF-1 LR3 is studied for its potential to promote protein synthesis in muscle tissue, support satellite cell activation (muscle stem cells), and influence how cells take up nutrients. Its extended half-life allows for sustained signaling compared to naturally occurring IGF-1.
