IGF-2 can act over its own receptor (IGF-2 receptorIGF-2R), which is a manose-6-phosphate transmembrane protein with undetermined actionsit is thought that it acts as a scavenger receptor by sequestering IGF-2 and IGF-1 from the extracellular medium and targeting them for destruction [103]

Skin wound healing: acute wounds, slow-healing wounds, and post-traumatic skin repair where collagen remodeling is a clinical priority Post-surgical tissue recovery: skin and soft tissue healing following surgical procedures, particularly where scar minimization and organized collagen deposition are desired Anti-aging and skin rejuvenation: wrinkle reduction, skin firmness, and surface texture improvement through topical or injectable GHK-Cu protocols Hair follicle stimulation: investigated for hair growth support in patients with hair thinning or loss where scalp vascularity and follicle reactivation are clinical targets Gastrointestinal mucosal healing: investigated for ulcerative colitis and GI mucosal repair through SIRT1/STAT3 pathway inhibition Combination wound healing protocols: used alongside BPC-157 and TB-500 to provide copper-dependent enzyme activation and gene expression regulation as part of a comprehensive tissue repair approach GHK-Cu is the peptide most commonly associated with skin applications in physician-supervised peptide therapy, and it occupies a distinct clinical role from the musculoskeletal-focused BPC-157 and TB-500

418 Rechallenge strategies, by contrast, operate under the premise of clonal evolution reversibility, whereby reintroducing previously used agents, often after a drug holiday, can resensitize tumors due to regrowth of drug-sensitive clones
