### §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.

## Body

## GHK-Cu: Collagen Scaffolding

GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring copper-binding tripeptide first isolated from human plasma.

### Plasma Levels and Age-Related Decline
Plasma GHK levels measure approximately 200 ng/mL at age 20 and decline to approximately 80 ng/mL by age 60 (human plasma measurements).

### Collagen and Extracellular Matrix Effects
In human dermal fibroblast cultures, GHK-Cu at nanomolar concentrations increases synthesis of collagen types I, III, and IV as well as elastin and glycosaminoglycans (preclinical, human cell studies). It also modulates matrix metalloproteinases and their inhibitors, supporting both synthesis and organized remodeling of collagen (mechanistic).

Placebo-controlled topical application studies in women around age 50 reported improved skin quality parameters and increased collagen deposition in skin biopsies (human).

No large-scale systemic human trials on collagen scaffolding outcomes are available.

### Wound Healing and Tissue Remodeling Context
A registered Phase 2 randomized double-blind trial (NCT07437586) is evaluating topical GHK-Cu gel versus vehicle for acute skin wound re-epithelialization in healthy adults (human trial, ongoing/registered).

Gene-expression studies in human cells link GHK-Cu exposure to patterns associated with improved fibroblast function and collagen reorganization (mechanistic).

### Summary of Evidence Tiers
- Age-related decline in circulating GHK: human data.
- Stimulation of collagen production: primarily preclinical (human fibroblasts in vitro) with limited supporting human topical biopsy data.
- Systemic tissue remodeling claims: no human data.

### §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.
