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
