The Role of IGF-1 LR3 in Age-Related Muscle Loss: What Does Research Say?
IGF-1 LR3, or Insulin-like Growth Factor-1 Long R3, is a recombinant protein engineered to enhance the properties of naturally occurring IGF-1, a hormone with growth-promoting effects similar to insulin. The LR3 variant increases the bioavailability and half-life of IGF-1, making it more effective for research and therapeutic uses, particularly in bodybuilding and regenerative medicine.
