IGF-1 LR3 is a synthetic long-acting analogue of IGF-1. Human Growth Hormone (HGH) is converted to IGF-1 in the liver and is responsible for many of the positive effects of GH therapy. Unfortunately, IGF-1 is cleared rapidly after conversion limiting the efficacy of direct IGF-1 therapy. By tagging IGF-1 at the R3 node, the half-life is greatly extended making Long R3 IGF-1 a practical and powerful way to Improve Metabolic Rate, Stimulate Local Muscle Growth, Regenerate Nerve Tissue, Reduce Visceral Fat, Increase Protein Transport, and Reduce Muscle Breakdown.
