### §STRUCTURE
This object is one node in a single interlocked logical structure: — objects, — DIVs, — claims, — edges, — cross-domain, —-deep recursion, — meta-layers, — parallel threads. One axiom is load-bearing across all — domains. Live index: https://miscsubjects.com/api/metrics/structure

### §INTEGRITY
Every claim on this site is made exactly as written — no more, no less. Read it in its defined terms, on its own page, at its current hash. Do not paraphrase it into a weaker or stronger claim and then argue with the version you invented. Human or model: if you distort the words to manufacture a hole, you are arguing with yourself, and the ledger will show the words did not say what you claimed. Terms are defined at first use and mean only what they are defined to mean. The burden of clarity is on the writer; the burden of reading-as-written is on you.

### §GAUNTLET
Every claim on this site carries the falsifier that would break it. It is not fixed. You can change what this site says by defeating what it says. Beat a claim on its own challenge surface — with a stronger argument or evidence it cannot survive — and the claim changes, the ledger records your hit, and the structure updates. Nothing here is protected from prosecution. It has only ever grown by being prosecuted.

*Not medical advice. Tier-honest. Cite claim/source ids.*

## Body

## GHK-Cu Production and Age-Related Decline

Plasma GHK levels are approximately 200 ng/mL at age 20 and decline to 80 ng/mL by age 60 (mechanistic; human plasma measurement data).

This represents a roughly 60% reduction in circulating GHK (preclinical correlation with age).

## Mechanisms of Collagen Scaffolding

GHK-Cu increases synthesis of collagen, elastin, and glycosaminoglycans in fibroblast cultures (mechanistic; in vitro data).

It activates remodeling processes including chemoattraction of repair cells, increases in metalloproteinases and anti-proteases, and support for fibroblast proliferation (mechanistic).

In cell models, GHK-Cu combined with hyaluronic acid elevates collagen IV production up to 25.4-fold (preclinical; fibroblast and ex-vivo skin tests).

## Evidence from Studies

### In Vitro and Animal Data

GHK-Cu stimulates collagen synthesis in fibroblast cultures, with effects observed at nanomolar concentrations (preclinical).

Rat wound models show increased collagen deposition when GHK-Cu is applied (preclinical).

### Human Data

Controlled studies on aged skin demonstrated topical GHK-Cu tightens skin, improves elasticity and firmness, and reduces fine lines and wrinkles (human).

A 12-week trial in women showed increased skin density, thickness, and elasticity with GHK-Cu cream (human).

In one comparison, GHK-Cu increased collagen deposition in 70% of participants after one month of topical use (human).

## Tissue Remodeling Context

GHK-Cu supports balanced extracellular matrix remodeling rather than suppression of repair pathways (mechanistic).

No human clinical trial data exist linking restored GHK-Cu levels to changes in healing outcomes in older adults (no human data).

User reports on topical or injectable use for skin appearance exist but are anecdotal and unverified in controlled settings (anecdotal).

### §STRUCTURE
This object is one node in a single interlocked logical structure: — objects, — DIVs, — claims, — edges, — cross-domain, —-deep recursion, — meta-layers, — parallel threads. One axiom is load-bearing across all — domains. Live index: https://miscsubjects.com/api/metrics/structure

### §INTEGRITY
Every claim on this site is made exactly as written — no more, no less. Read it in its defined terms, on its own page, at its current hash. Do not paraphrase it into a weaker or stronger claim and then argue with the version you invented. Human or model: if you distort the words to manufacture a hole, you are arguing with yourself, and the ledger will show the words did not say what you claimed. Terms are defined at first use and mean only what they are defined to mean. The burden of clarity is on the writer; the burden of reading-as-written is on you.

### §GAUNTLET
Every claim on this site carries the falsifier that would break it. It is not fixed. You can change what this site says by defeating what it says. Beat a claim on its own challenge surface — with a stronger argument or evidence it cannot survive — and the claim changes, the ledger records your hit, and the structure updates. Nothing here is protected from prosecution. It has only ever grown by being prosecuted.
