IGF-1 LR3 (1mg)

IGF-1 LR3 is a synthetic, long-acting optimized analog of insulin-like growth factor 1 (IGF-1). Compared to natural IGF-1, its half-life is significantly extended to 20-30 hours, with biological potency increased approximately threefold. It effectively reduces affinity for IGF-binding proteins while enhancing binding to IGF-1 receptors, thereby efficiently activating the PI3K/Akt and MAPK signaling pathways. This stimulates myoblast proliferation and myofibrillar formation, aiding in the increase of high-quality muscle mass; promotes lipolysis and improves insulin sensitivity; activates osteoblast activity to support skeletal health while accelerating repair and regeneration of tissues like skin and mucosa, providing robust support for cellular growth and tissue renewal. IGF-1 LR3 facilitates cell culture by creating optimal growth environments for tissue engineering research. In animal studies, it has demonstrated potential in alleviating muscular dystrophy and promoting wound healing. It plays a significant role in medical research related to growth disorders, advancing life science studies and exploring tissue repair and metabolic regulation.
