What is IGF-1 LR3?
IGF-1 LR3 is a modified version of IGF-1 with 13 times the half-life of native IGF-1. It promotes anabolic signaling, muscle hyperplasia, and cellular repair with extended bioavailability.
Key Benefits & Mechanisms
Promotes muscle hyperplasia (new muscle cells)
Extended half-life vs native IGF-1
Enhanced protein synthesis
Improved nutrient partitioning
Anti-catabolic effects
Cellular repair and regeneration
Fat metabolism enhancement
Research Summary
IGF-1 LR3 has extensive in vitro and animal data. Its role in muscle hyperplasia is well-documented. The extended half-life modification provides practical advantages over native IGF-1.
