About Peptide GHK-Cu
The research became more interesting when the familiar skin ingredient led to experiments on learning. I wanted more room for the learning question.
Why the memory question
Peptide GHK-Cu is an editorial site about a very short molecule with a surprisingly wide research life. The aged-mouse learning experiment led my curiosity towards learning and nerve injury. An animal doing better in a task gives the broad language of repair something concrete to explain.
I expected skin care to supply the whole story. The mouse results sent me towards memory; the use of free GHK, rather than copper-bound GHK-Cu, complicated the journey. The complication is welcome. It makes the chemical name consequential instead of decorative.
Skin and hair still deserve their space here. Small topical trials are closer to ordinary human experience than a mouse maze, and the combination hair trial is worth understanding in its own right. I distrust a case assembled from attractive outcomes when the tested molecule changes along the way.
Advice, appointments and products
These essays are an attempt to understand published experiments. Nothing I write can evaluate a person's symptoms, medicines or suitability for treatment, and the site provides no medical advice. It has no patient appointments, prescription service or product checkout.
I cannot get far towards a treatment claim while human neurological trials and validated human systemic pharmacokinetics are both missing. The rat blood study cannot supply the missing human measurements. I would happily retire those questions after experiments answer them.
Reports from skin-care and peptide communities are anecdotal accounts rather than clinical evidence. Their favourable and unfavourable impressions make useful questions, especially when they disagree. They cannot establish an amount, a schedule or a diagnosis.
