Topical GHK-Cu seems like a waste to me. Your skin is a barrier, no way a big ass positively charged peptide like that is getting through in significant amounts. A needle bypass…#697 · 24 September 2026

Questions
- What do GHK-Cu user reports say people use it for?
- A confession counts when its text matches a fixed use list: skin, hair, a wound or scar, healing or recovery, topical use, the face, or injection. The use phrase in the most confessions is skin or complexion: 14 of 58 (24.1%). A denial in the preceding words does not count. These are phrase matches over anonymous published stories, not clinical incidence.
- How many confessions are in this GHK-Cu count?
- 58 published confessions are tagged GHK-Cu. The site has no accounts, so this is a count of submissions, not a verified count of distinct people. Published dates run from 20 May 2026 through 14 October 2026.
- How are GHK-Cu timelines counted?
- 3 confessions write an explicit day number, 7 confessions write an explicit week number, and 7 write an explicit month number. Months are not converted into weeks, and weeks are not converted into days. A confession can land in more than one bucket when it names more than one number.
- What GHK-Cu side effects do users report?
- A confession counts when its text matches the shared phrase list (for example nausea, constipation, heart rate, palpitations). A denial in the preceding words ("no nausea") does not count. The side-effect phrases users report most often are hair shedding and injection-site reaction (tied): 2 of 58 confessions (3.4%). Silence is not recorded: people who never name an effect are in the denominator only.
- Are these GHK-Cu doses a recommendation?
- This is not a dosing recommendation. 1 of 58 confessions write a figure next to GHK-Cu or GHK. Figures are kept when they sit near that name, and dropped when they sit near another compound, a price, or a vial size. One distinct figure counts once per confession. No figure was frequent enough to list.
- Do these percentages show what GHK-Cu causes?
- A percentage is the share of published confessions that used a phrase. Figures on this page are phrase matches over anonymous published stories, not clinical incidence.
Methodology
Cohort: confessions with status published and a GHK-Cu tag. Data through 14 October 2026. The page is cached and regenerated about once an hour from that query.
There is no structured field for side effect, use, dose, week, or outcome. Matches are case-insensitive phrases. A phrase that nobody used stays in the table at zero. “Tired”, “sleep”, “heart”, and “skin” alone are not scored; those words show up in stories that are not about a side effect.
Figures on this page are phrase matches over anonymous published stories, not clinical incidence.
This is not a dosing recommendation. Doses are not a protocol. Weight figures, where this page shows them, are not a result you should expect. Nothing on this page is a finding from a trial.
Editorial rules for what gets published are on the methodology page. Vendor names are not repeated here.
