What is known, and what is missing
Measured on: wrinkle depth and firmness; no timing attributable to this peptide alone.
Its collagen-signalling evidence is in vitro (fibroblast matrix synthesis), which cannot supply a human timeline. Every clinical result comes from blends — most often with palmitoyl tetrapeptide-7 — so no visit at which skin changed can be assigned to pal-GHK itself. Dosed at parts-per-million from a dilute supplier solution; missing is any single-agent vehicle-controlled trial of any length.
In-vitro fibroblast studies plus peptide-blend clinical work; no single-agent human trial identified.
