Comparison Table (Structure, Pathway, Research Classification) Each compounds classification reflects its underlying mechanism rather than a shared fat-loss peptide category: AOD-9604 remains research-stage and inconclusive, GLP-1 S has the most extensive clinical backing of the three, and tesamorelin occupies a narrower but well-documented niche in visceral fat and GH-axis research

The wound healing cascade and GHK-Cu: Normal wound healing occurs in four overlapping phases: Hemostasis clotting Inflammation immune cell recruitment Proliferation new tissue formation Remodeling scar maturation GHK-Cu appears to favorably influence phases 2, 3, and 4 simultaneously: In the inflammatory phase , it reduces pro-inflammatory cytokines (IL-6, TNF-) while preserving necessary immune signaling In the proliferative phase , it stimulates keratinocyte migration and fibroblast proliferation, accelerating epithelial coverage In the remodeling phase , it promotes type I collagen deposition over type III (scar) collagen, leading to better scar outcomes This multi-phase tissue repair activity makes GHK-Cu a compound of interest when studied alongside other regenerative peptides
But how do they stack up against each other

(Source 2, 3) Because glutathione is a small peptide made from amino acids, it likely gets broken down in the digestive system instead of absorbed intact
