Why this question
Why I put “legit” beside GHK-Cu
A yes-or-no reputation seemed too blunt for a molecule whose experiments keep producing more particular answers.
The name is a question that remains open
Legit GHK-Cu is one person’s reading of the published research. It offers no medical advice. There is no treatment service or product catalogue here, and no prescriptions, shipping or appointments.
I chose “legit” because a molecule can have a respectable laboratory record and an inflated reputation at the same time. The collagen experiment is unusually specific: production increased without an increase in cell number. The hair trial has a result worth discussing and another ingredient that cannot be removed from its credit. Calling the entire subject either convincing or nonsense would flatten both.
The discovery in plasma, described in the skin-regeneration review, also gives the subject an origin beyond skin care. The odd beginning interests me, while safety still needs evidence for an endogenous molecule and its decline with age leaves the case for replacement open.
A verdict that can wait
The post-laser trial helped sharpen my skepticism. Satisfaction and measured redness diverged. I had been too quick to treat a favorable human impression as evidence of repair; the objective result makes that shortcut difficult to defend.
I’m impatient for human studies that preserve the identity of the peptide, account for the delivery material and measure the outcome being claimed. A result from another team would carry particular value where the broad claims still depend heavily on the originating group. The current literature leaves room for curiosity without making certainty available.
I can defend an experiment and dispute the reputation built around it. That is the unresolved attraction of GHK-Cu for me. A better human result might change the balance; a confident slogan cannot. Corrections to a study description belong on the contact page, while personal treatment questions fall outside what this site can answer.
