IGF-1 LR3 is an improved analog of naturally occurring Insulin-like Growth Factor 1. By replacing Glutamic acid with Arginine at position 3 (hence the name “Long Arg3”), this peptide bypasses binding proteins in the blood. This modification significantly extends its half-life to about 20–30 hours, compared to the few minutes of standard IGF-1.
Key Research Benefits:
Enhanced Muscle Hyperplasia: Studied for its ability to promote the growth of new muscle cells rather than just increasing the size of existing ones.
Improved Recovery: Known for accelerating tissue repair and reducing downtime after intense physical activity.
Fat Metabolism: Investigated for its role in encouraging the body to use stored fat for energy.
Anti-Aging Potential: Explored in longevity research for its cellular repair and regeneration properties.
