We used TinyFish to discover and retrieve current public pages, then checked the product offers in a browser. The notes below distinguish manufacturer information from medical guidance and research.
Provider offer · Checked September 25, 2026
Starting $64.99/month and Copper Peptide 2% are provider statements. Full base, quantity, patient eligibility, final charge and finished-formula clinical results were not independently verified.
Manufacturer offer · Checked September 25, 2026
US page lists 15 mL at $93, a balm format and Copper Tripeptide-1 Palmitamide. Manufacturer study summaries are not a published head-to-head comparison.
Manufacturer offer · Checked September 25, 2026
Live browser page lists selected 1.7 oz at $86 one-time or $73.10 subscription. An alternate text fetch showed older content; current browser text was used. Full ingredient declaration was not established from the readable capture.
Manufacturer evidence summary · Checked September 25, 2026
Separates eight-week consumer perception, supplier peptide-complex research and laboratory evidence. Supplier ingredient data are not a finished-cream trial.
Manufacturer offer · Checked September 25, 2026
US page displayed 1 fl oz at $199 one-time or $169.15 subscription. Several headline results are self-assessments or best results, and a menopause study concerns an ingredient in a different cream vehicle.
Regulatory guidance · Checked September 25, 2026
Compounded drugs are not FDA-approved. General guidance does not determine the quality or suitability of a particular prescription.
Regulatory guidance · Checked September 25, 2026
Intended use and claims help determine regulatory category. A clinical-sounding cosmetic name is not proof of drug approval.
Regulatory guidance · Checked September 25, 2026
Ingredient-order conventions have exceptions, including ingredients at 1% or less. A position in a list is not a disclosed exact concentration.
Dermatology guidance · Checked September 25, 2026
General moisturizer advice; not an endorsement of any product reviewed here.
Dermatology guidance · Checked September 25, 2026
A small-area home product trial is different from diagnostic patch testing. Prescription and post-procedure use need the treating clinician’s instructions.
Dermatology guidance · Checked September 25, 2026
Sets expectations for moisturizer and sun protection. Does not verify copper peptide superiority.
Dermatology guidance · Checked September 25, 2026
Discusses skin changes and care during menopause. It is not proof that any featured formula treats hormonal changes.
Human study abstract · Checked September 25, 2026
Small post-procedure trial with 13 completers. No statistically significant objective between-group advantage; satisfaction favored GHK-Cu. Not a trial of the four current products or routine use on intact skin.
