Identity and synonyms
AHK-Cu is distinct from GHK-Cu.
Peptide or peptide-related · Copper–peptide complex
Detailed molecular class: Copper tripeptide
Supplied sequence or chemical reference
See identity note; no supplier sequence accepted as verification.
Mechanism
Effects on dermal papilla cells and hair follicles investigated.
Evidence and critical reading
Reported scientific and empirical uses
Skin, hair and cosmetics
Copper complex distinct from GHK-Cu, cited for hair/dermal papilla.
Human evidence
No controlled human efficacy finding was verified for the exact catalog identity in this screen.
Preclinical evidence
Human follicles ex vivo and cultured cells showed changes; human tissue outside the body is not a treated-patient trial.
Critical reading and limitations
The verified study used ex vivo human follicles/cells, not a treated-person trial.
Evidence applies to the exact molecule, formulation, route, population and endpoint studied. Supplier identity, purity and clinical equivalence are unverified.
Source-specific regimens
Descriptive source observations, not individual recommendations.
Regulatory product labeling
No numerical human dose is assigned: reviewed sources did not verify a regimen attributable to this material, route and indication. Other molecules’ doses, animal exposures, vial amounts and dietary requirements are not substituted.
Human-study exposure
No numerical human dose is assigned: reviewed sources did not verify a regimen attributable to this material, route and indication. Other molecules’ doses, animal exposures, vial amounts and dietary requirements are not substituted.
Empirical handbook
No numerical human dose is assigned: reviewed sources did not verify a regimen attributable to this material, route and indication. Other molecules’ doses, animal exposures, vial amounts and dietary requirements are not substituted.
Regulation and safety
Jurisdiction-specific regulatory context
Jurisdiction-specific approval not verified in this card; do not infer global nonapproval.
Adverse effects and unknowns
Human safety, contraindications and interactions are not adequately established for the catalog product. Missing reports are not evidence of safety.
Do not transfer efficacy/safety between copper peptides, cosmetics and injection.
Contraindications
See supported safety statements and exact product label; a complete contraindication set has not been established for this catalog material.
A complete list must match the exact authorized product. For experimental materials without verified human labeling, a complete contraindication set is not established here. No list does not mean safety.
Interactions
Only explicitly cited interactions may be asserted; unstudied combinations remain unknown, not interaction-free.
Separate documented interaction, pharmacologic plausibility and unknown interaction. Absence of a blend trial does not establish compatibility.
Studies and trials
