What is IGF-1 LR3?
Research Focus: Muscle, Tissue Repair
Insulin-like Growth Factor 1 Long R3 (IGF-1 LR3) is a modified, long-acting analog of IGF-1. It is highly studied for its potent anabolic effects on muscle and tissue repair.
At a Glance
IGF-1 is a hormone similar in structure to insulin, primarily produced by the liver in response to GH. The LR3 modification prevents it from binding strongly to IGF-binding proteins, significantly extending its half-life and bioavailability. This section provides a general overview of its research context.
About IGF-1 LR3
IGF-1 is a hormone similar in structure to insulin, primarily produced by the liver in response to GH. The LR3 modification prevents it from binding strongly to IGF-binding proteins, significantly extending its half-life and bioavailability.
How It Works
Anabolic Signaling
Activates the IGF-1 receptor, promoting protein synthesis, cell proliferation, and muscle cell differentiation.
Extended Half-Life
The R3 modification allows it to circulate longer in the bloodstream, providing sustained anabolic signaling.
Current Research Insights
Localized and Systemic Anabolism
Researchers use IGF-1 LR3 to study both systemic muscle growth and localized tissue repair when injected near an injury site.
Areas of Study
Muscle Hypertrophy
Investigated for maximizing muscle growth and recovery.
Tissue Regeneration
Studied for accelerating the repair of damaged tendons, ligaments, and cartilage.
