Description
SP IGF-1 LR3 (Insulin-Like Growth Factor-1 Long R3) is a modified peptide with an extended half-life compared to standard IGF-1. Due to its prolonged activity, it is commonly used in sports and biochemical research focused on muscle development, recovery processes, and anabolic signaling. IGF-1 LR3 interacts with IGF receptors and insulin receptors, making it a subject of interest for studies related to muscle hypertrophy and nutrient uptake.
