In stock
A modified version of insulin-like growth factor-1 that has a longer half-life and stronger activity in the body. It works by binding to IGF-1 receptors and activating pathways involved in cell growth, protein synthesis, and muscle tissue repair, while also influencing nutrient partitioning—meaning your body is more likely to use nutrients for muscle growth rather than fat storage.
