The signal, not the noise.
PEPHORMIA grades the real peptide & hormone science — strong, human, weak, or mechanistic — so you see what the evidence actually says. Then we turn that trusted core into products: cosmetic topicals, cited digital guides, and print tools. Honest about limits, by design.
Every claim, graded honestly.
We don't invent claims — we aggregate peer-reviewed research and tag each finding by how strong the evidence really is. This is the four-tier evidence box you'll see across the whole platform.
GHK-Cu supports the look of firmer, smoother skin over a 12-week course.
Leyden 2005, 67–71 women, 12-week study — the stronger human data.
In one small comparison, topical GHK-Cu raised collagen response in more subjects than vitamin C or retinoic acid.
Abdulghani 1998, ~10 subjects — small n, treat as preliminary.
GHK-Cu modulates a broad set of genes tied to repair in cell models.
Preclinical / in-vitro only — mechanism, not proven human outcome.
One trusted core, three ways to buy.
