IGF-1 DES (Des(1-3)IGF-1) is a truncated analog of insulin-like growth factor-1, lacking the first three amino acids at the N-terminus. This modification reduces binding to IGF-binding proteins (IGFBPs), resulting in higher bioavailability and ~10x greater potency than native IGF-1. With a short half-life of 20–30 minutes, it acts locally when injected intramuscularly, promoting site-specific muscle growth, satellite cell activation, and tissue repair via direct activation of the IGF-1 receptor and downstream PI3K/Akt/mTOR pathways. It is used in research for muscle regeneration, metabolic studies, and localized anabolic effects.
