Why this scored 46/100
Neurogan Health GHK-Cu Copper Peptide Tablets deliver 2 mg of the tripeptide glycyl-histidyl-lysine chelated with copper per serving, marketed as an oral supplement for skin health. The core problem is mechanistic, not brand-related. GHK-Cu is a real molecule with a real evidence base — but exclusively for topical application. Every clinical study showing skin-remodeling, hair-growth, or wound-healing effects (Pickart 2015 reviews; Zhou 2020) used GHK-Cu delivered topically as a cream or serum, or intradermally via microneedling. Oral GHK-Cu is a peptide that will be enzymatically hydrolyzed to its constituent amino acids in the stomach and small intestine; no published human PK data shows intact GHK-Cu reaching skin capillaries from an oral tablet. Adding elemental copper (2 mg) does contribute to daily copper intake (RDA ~900 μg), but that is a mineral effect, not a peptide effect. Rejected — the product mechanism as marketed is not supported by human data, and the 'first of its kind' framing masks that fact.

Evidence & sources
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.
How to read the Evidence dimension
- 80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
- 60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
- 40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
- 20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
- 0–19: No credible evidence base or unverifiable claims.
