Why this tier
Our material names Matrixyl 3000 as the strongest topical signal peptide for collagen and wrinkle-depth reduction but cites no study, concentration or protocol for it.
What it is
Matrixyl 3000 is described in our material as the strongest topical signal peptide for collagen, a compound that instructs fibroblasts to produce collagen rather than supplying a cofactor the way GHK-Cu does. It is paired with GHK-Cu in our skin protocol on exactly that logic. Our sources publish no concentration, dosing or side effect data for it.
How it works
Our material classifies Matrixyl 3000 as a signal peptide: it triggers fibroblasts, the cells in the dermis that manufacture structural protein, to produce collagen. That is a different job from a carrier peptide like GHK-Cu, which delivers the copper that the enzyme lysyl oxidase needs to cross-link collagen into functional fibres. One sends the instruction, the other supplies the material, which is why our sources recommend combining a carrier peptide with a signal peptide rather than choosing between them.
Commonly researched ranges
Not established in available literature. Our sources describe Matrixyl 3000 without publishing a dosing figure, so Claritide does not print one.

Where this sits with the FDA
Regulated as a cosmetic ingredient rather than as a drug. It does not appear on FDA’s compounding category lists or the 503A bulks list.
Primary sourceWADA status
Not named on the 2026 List. A cosmetic ingredient rather than a pharmacological substance in the S0 sense; we do not state a status.
We looked and could not resolve it. This is not the same as "not prohibited". Treat it as unresolved and check with your federation before competing.
There is nothing to mix
Not applicable. None of the published routes for this compound take a diluent, so there is no concentration to calculate and no beyond-use window to track.

Limited coverage
Matrixyl 3000 appears in two comparison tables on our GHK-Cu page. We cite no study, no concentration, no application protocol and no side effect data for it.
What our sources do say
Our anti-aging comparison table gives its role as "signal peptide · triggers fibroblast collagen production" and its best use as "wrinkle depth reduction, firmness". Our GHK-Cu FAQ calls it "the strongest topical signal peptide for collagen".
Carrier versus signal: the reason it is paired with GHK-Cu
This distinction is the useful part of the record.
GHK-Cu is a carrier peptide. It delivers copper to lysyl oxidase, the enzyme that cross-links collagen and elastin into functional load-bearing fibres. Without copper, new collagen is structurally weak.
Matrixyl 3000 is a signal peptide. It instructs fibroblasts to make collagen in the first place.
Those are different jobs. Our GHK-Cu page states the practical conclusion directly: combining a carrier peptide like GHK-Cu with a signal peptide like Matrixyl yields the best collagen-boosting results, alongside retinol and daily sunscreen. That is the entire basis of the Skin Stack in our stacks library.
What we cannot tell you
Our material gives no percentage concentration, no application frequency, no expected timeline, no compatibility notes and no side effect profile for Matrixyl 3000. The GHK-Cu compatibility rules, which say to avoid layering with strong acids or pure L-ascorbic acid, are documented for GHK-Cu specifically, and we do not extend them to a compound our sources never tested.
This sits in the lowest evidence tier not because the compound is poorly regarded, but because our own published material never examined it.
