For Formulators & Cosmetic Chemists
A formulator does not need a supplier's marketing — they need the active, its batch identity, and honest technical reading they can pressure-test on the bench. Pepoderma supplies GHK-Cu, Matrixyl, SNAP-8, and AHK-Cu with sample quantities for compatibility work and a batch COA, then points you to vetted Journal field guides on stability, carriers, and layering rather than restating numbers we would rather you verify yourself.
Actives for this brief

How we support you
We ship sample quantities sized for compatibility, stability, and layering trials — enough to take an active through a real formulation screen before you commit a production MOQ.
Each active arrives with a batch-specific certificate of analysis, so the material you screen on the bench is documented and the production lot maps back to what you validated.
Compatibility, emulsion stability, carrier choice, and layering with retinol or vitamin C are covered in our Journal field guides. We link you to the specifics rather than restating use-levels and pH windows in a sales sheet — verify them against your own system.
Questions about the salt form, the carrier a copper peptide ships in, or how a lot was characterized go to people who can answer them — not a ticket queue — so an R&D blocker does not stall a development timeline.
Your brief, our side
You are the person who finds out whether an active survives the formula. A copper peptide that discolours in the wrong base, a signal peptide that needs the right carrier, two actives that should not share a phase — these are bench problems, and they are yours to solve before a brief becomes a stable product. What you need from a supplier is honest material, honest documentation, and technical reading you can actually pressure-test, not a claim sheet that collapses on contact with your system.
Pepoderma's side is to give you the active in a sample you can work with, the batch identity to characterize it, and field guides that treat you as a chemist — covering stability in emulsions, carrier compatibility, and layering with retinol and vitamin C, with the numbers in the article so you can check them against your own work. The development decisions stay yours; our job is to make the inputs trustworthy.

Sourcing questions
Yes — sampling is the normal first step for bench work. We ship a sample quantity large enough to run compatibility, stability, and layering trials, with the batch documentation, so you can take an active through a real screen before committing a production MOQ. Tell us the actives and the kind of base you are working in and we scope the sample.
We point you to our Journal field guides for that, rather than restating numbers in a sales sheet. The guides on GHK-Cu, emulsion stability, and layering with retinol and vitamin C cover the technical specifics — and we would rather you verify them against your own formulation than treat a supplier figure as gospel. For anything specific to your system, ask us directly and we will give you a straight answer or tell you what to test.
The form is documented on the batch certificate of analysis and the SDS that ship with each active. Because the salt form and any carrier matter to how a peptide behaves in a formula, we are specific about what you are getting rather than leaving it to be inferred. If you need a particular form for a development, raise it when you request the sample and we will confirm what is available.
Yes — questions about how a lot was characterized, the counter-ion, or the carrier go to people who can answer them rather than a generic queue. We keep a direct line for the sourcing-side technical questions that come up during development, so an R&D blocker on the material does not sit unanswered while a timeline runs.
