GHK-Cu operates through a different axis fibroblast activation, copper trafficking, and broad gene modulation without engaging the retinoid receptor family
Go slowly A slow, steady injection over several seconds protects the peptide's structure far better than a quick push

From an experimental design perspective, the key hypothesis is not that the peptides duplicate each others effects, but rather that they might support different rate-limiting steps in repair, such as cell recruitment to the injury site, fibroblast function, extracellular matrix organization, angiogenesis, and the transition from inflammatory signaling to remodeling
Once reconstituted, store at 2-8C and use promptly
Regulatory Approval The path to approval follows multi-phase trials: preclinical work, Phase I safety, Phase II dose-finding and efficacy signals, and larger Phase III trials
