Coach Dj Vanilla Face on Instagram: "IGF analogs, such as IGF-1 LR3, IGF-1 DES, and PEGylated variants, are modified to enhance bioavailability and anabolic potential. These analogs aim to mimic IGF-1’s effects by binding to IGF-1 receptors and activating key anabolic pathways, including PI3K/AKT (protein synthesis and muscle preservation) and MAPK (cell division and tissue repair). IGF-1 LR3 is the most common analog, with an arginine substitution at position 3 that increases resistance to IGF-
