Full stated quantity, and nothing overstated — every active's purity and identity are measured, not claimed, and printed on its batch COA with counter-ion and water.

GHK-CuThe cosmetic-peptide canonical
Isolated from human plasma in 1973 and the textbook example of an endogenous copper-peptide complex, GHK-Cu is the reference active for cosmetic anti-aging formulation. Pepoderma ships it ≥99.0% HPLC with copper-content verification on every release packet so the diagnostic blue colour you receive is the same blue your finished serum should hold through shelf-life.

AHK-CuThe hair-follicle copper variant
The Ala-His-Lys structural analog of GHK-Cu, with the N-terminal glycine swapped for alanine. The substitution shifts the molecule's tissue-distribution preference toward the scalp and follicle, which is why AHK-Cu lives in hair-regrowth serums rather than dermal-repair creams. Mutually compatible with GHK-Cu in combined scalp-plus-skin programmes.

Snap-8The expression-line wrinkle reducer
An 8-amino-acid acetylated peptide mimetic of the SNAP-25 N-terminus, designed as an extension of the classic Argireline molecule. Snap-8 lives in topical formulations targeting forehead, glabellar, and periocular expression lines. Typical use levels settle at 5–8 % of the finished product; we stock it kilo-scale for OEM finished-product runs.
View Active
MatrixylThe collagen-mimetic anti-aging peptide
A palmitic-acid-conjugated pentapeptide based on the KTTKS fragment of human procollagen type I — the palmitoyl group is a delivery vehicle that lets the peptide cross the stratum corneum and reach dermal fibroblasts. Mechanistically complementary with GHK-Cu and Snap-8, the three peptides stack cleanly in a multi-active anti-aging serum.

The supporting diluent is clearly separated from the cosmetic-active specifications; every featured peptide retains its full INCI documentation and formulation-stability data.

Brand Stories
Pepoderma's partner-brand stories will live here as soon as our first cohort of finished-product launches give us consented quotes. The frame is reserved; the names are coming.
“An indie clean-beauty founder, on bringing their first copper-peptide serum from sample to shelf with the use-level and carrier guidance that shipped alongside the active.”
“An R&D chemist at an established skincare line, on the lot-specific data packet that let them move a copper-peptide active into a finished formulation in weeks rather than months.”
“A med-aesthetic OEM partner, on the kilo-scale Snap-8 bulk lots that let them ship a finished expression-line serum to a clinic-channel customer on schedule.”
Where formulators find their next hero
Pepoderma supports brand programmes from the first sample request through the finished-product launch — and publishes the formulation references in between. Pick the doorway that matches where your programme is today.
26 INCI-documented cosmetic peptide actives — Copper Tripeptide-1, AHK-Cu, Acetyl Octapeptide-3, Palmitoyl Pentapeptide-4. Lot-specific data packet on every release.
Sampling, custom-blend formulation, and finished-goods OEM for brand programmes. Three workflows — sample, custom blend, finished — depending on where your brand programme is in its development.
Formulation field guides, compatibility matrices, and use-level references for every featured active. Designed to live on a chemist's bookmarks bar.
Editorial briefs for cosmetic formulators and brand founders — GHK-Cu in 2026, Argireline vs. SNAP-8, peptide stability in aqueous serums, the seven actives every modern indie brand should stock.

Documented like a paper, sold like an active
Every shipment leaves the atelier with the batch's Certificate of Analysis, HPLC purity, mass-spec identity, and microbial limits. INCI verification, stability data in our reference aqueous serum, and copper-content verification (for copper-peptide actives) are included so a chemist answers their own QA before the first sample fills a laboratory beaker.
