IGF-LR3
IGF-1 LR3 – Overview
IGF-1 LR3 is a long-acting synthetic analog of IGF-1 designed to promote muscle growth, tissue repair, and recovery.
The “LR3” modification extends its half-life, allowing longer-lasting activity in the body compared to natural IGF-1.
How IGF-1 LR3 Works
IGF-1 LR3 works by:
✔ Activating IGF-1 receptors
-
Stimulates anabolic pathways in muscle cells
-
Promotes protein synthesis and cellular growth
✔ Enhancing muscle repair and regeneration
-
Activates satellite cells for muscle tissue repair
-
Speeds recovery from exercise or injury
✔ Supporting growth of lean tissue
-
Promotes hypertrophy and strength gains
-
Helps maintain lean mass during calorie restriction
✔ Improving nutrient utilization
-
Enhances amino acid uptake by cells
-
Supports overall metabolic efficiency
