IGF-1 LR3 is a modified version of IGF-1, a growth factor that occurs naturally in the body. The modification makes it more stable and longer-lasting — roughly three times more potent with about double the half-life — which is why it's widely used in cellular growth research.

In research, it has been studied for its effects on how cells take up glucose and use fat for energy, and on muscle repair and growth, partly through its interaction with myostatin (the signal that normally limits muscle growth).

Key Terms:

• IGF-1 (Insulin-like Growth Factor 1): A natural growth factor involved in cell growth and repair.
• Half-life: How long a compound stays active in the body before breaking down.
• Myostatin: A natural signal that limits how much muscle grows.
