Description
IGF-1 LR3 (Insulin-like Growth Factor-1 Long Arg3) is a synthetic, modified analog of human IGF-1 designed to have a much longer half-life (20–30 hours) and higher potency than naturally occurring IGF-1. It is used in research and, under medical supervision, for performance optimization to promote muscle growth, fat loss, and tissue repair by stimulating muscle satellite cells to proliferate and differentiate
- Accelerated Muscle Growth (Hypertrophy/Hyperplasia): IGF-1 LR3 drives muscle development by increasing protein synthesis and stimulating the proliferation of muscle satellite cells, which can lead to increased muscle cell numbers. It is considered roughly three times more potent than IGF-1, with studies suggesting it is around 2.5 to 3 times more anabolic in muscle tissue.
- Enhanced Recovery and Healing: It accelerates tissue repair and regeneration, making it effective for recovering from injuries to muscles, tendons, and connective tissues, as well as reducing downtime between workouts.
- Improved Fat Loss: It increases fat metabolism by improving insulin sensitivity and encouraging the body to use fat for energy instead of glucose.
- Increased Nutrient Partitioning: It helps improve how the body uses nutrients, directing them toward muscle tissue rather than fat storage.
- Extended Bioavailability: Unlike natural IGF-1, which breaks down in minutes, the LR3 modification prevents it from binding to proteins that would normally neutralize it, allowing it to remain active in the body for nearly a full day
