What changed?
A sourced timeline of research records and material development changes tracked by BACToBasics for GHK-Cu. Research-publication dates and clinical-development event dates are labeled separately so they are not mistaken for the same type of update.

Latest development activity
Verified 2026-09-05 · Early human evidence — topical route · No established development program
GHK-Cu has small human studies in topical/cosmetic contexts, but that route-limited evidence does not establish an injectable clinical-development program.
Open source ↗Latest research record by publication date
Published 2026 · Regulatory · Regulatory / safety review
FDA specifically distinguishes injectable GHK-Cu from topical use and notes limited human safety data for injectable routes.
Open source ↗Tracked timeline
Development changes are dated to the underlying milestone. Research-source entries use the study or source publication year currently stored in the Research Library; that year is not presented as the date BACToBasics added the record.

Regulatory · Regulatory / safety review
FDA specifically distinguishes injectable GHK-Cu from topical use and notes limited human safety data for injectable routes.
Human intervention · Randomized topical human study
A small human study evaluated a topical GHK-Cu-containing skin regimen after laser resurfacing.
Following a compound creates a clean baseline from the updates currently known. When BACToBasics later records a new research source or material development change, the My Tools update badge can surface it as new for you.
BACToBasics provides educational research organization only. A development milestone does not predict future approval, and a research record does not establish that a compound is safe, effective, approved, or appropriate for use.
