And unlike other molecules in longevity science, its been tested across an unusually broad range of models: from fruit flies to non-human primates, and from human fibroblasts to frog embryos

Overview GHK-Cu is a copper-associated tripeptide complex examined in research involving metal coordination, cell signaling, gene expression, extracellular-matrix regulation, proteostasis, oxidative variables, and tissue-specific cellular models
The combination of human-identical peptides plus protective delivery results in molecules that can influence localized tissue repair, modulate immune signaling to reduce inflammation, support mitochondrial NAD+ pathways for energy via NMN, or encourage collagen synthesis for skin improvement, which together explain the breadth of benefits people report when they use these targeted protocols consistently
Anything that promotes new blood vessel formation is a theoretical concern in the context of a tumor's blood supply, and the responsible default is caution
