Palmitoyl Tripeptide-1
Price and cost-per-mg comparison
Palmitoyl Tripeptide-1 (Pal-GHK) is a fatty-acid-conjugated form of the copper-binding tripeptide GHK (glycine-histidine-lysine), widely used in cosmetic formulations targeting skin firmness and matrix support. GHK is a naturally occurring human plasma peptide that modulates collagen and elastin synthesis, matrix remodeling enzyme activity, and antioxidant gene expression. Conjugating GHK to palmitic acid (a fatty acid) significantly improves transdermal penetration, allowing the peptide to reach the fibroblast-rich dermis from topical application — addressing the primary limitation of unmodified GHK, which does not readily cross the stratum corneum barrier. Pal-GHK vs GHK-Cu: Palmitoyl Tripeptide-1 (Pal-GHK) and GHK-Cu (copper peptide) derive from the same GHK tripeptide backbone but are formulated differently. GHK-Cu complexes GHK with copper(II) ions to leverage the copper-mediated wound healing and antioxidant mechanisms of the peptide. Pal-GHK conjugates GHK with palmitic acid for improved dermal penetration without the copper component. Both are used in anti-aging cosmetic formulations; GHK-Cu is used in injectable/serum contexts where copper activity is desired, while Pal-GHK appears predominantly in cosmetic skincare products where lipid-conjugated delivery is the priority. Matrixyl Synthe'6 context: Palmitoyl Tripeptide-1 is a primary active in Sederma's Matrixyl Synthe'6 formulation, which combines six components proposed to support six key structural proteins of the skin matrix: collagen I, III, and IV, fibronectin, laminin-5, and hyaluronic acid. The combination positions Pal-GHK as the collagen-stimulating component within a broader matrix-targeting blend, distinguishing Matrixyl Synthe'6 from the original Matrixyl (palmitoyl pentapeptide-4) and Matrixyl 3000 formulations. Products containing Matrixyl Synthe'6 list palmitoyl tripeptide-1 as an INCI ingredient alongside palmitoyl tetrapeptide-38 and other actives. Research and formulation: In vitro studies on palmitoyl tripeptide-1 show stimulation of collagen I and III synthesis in human fibroblast cultures. Clinical evidence is primarily from manufacturer-sponsored cosmetic studies showing improvements in skin firmness metrics. Palmitoyl Tripeptide-1 is included in the Cosmetics Europe Colipa ingredient database; it is not classified as a drug in any major jurisdiction. Concentrations in cosmetic formulations typically range from 2–5% of the palmitoyl tripeptide-1 ingredient solution (peptide content within the solution is lower, per the Sederma concentrate formulation). It is available exclusively in topical cosmetic form — there is no injectable or clinical application for this compound.

How these prices are computed
The short version. The methodology page has the rest.
Source
Prices are read from each vendor's own store feed or product markup (Vendor feed). Every row says which source it came from and when it was read. Prices parsed from page text are not in this index.
$/mg
Listed price ÷ stated milligrams, converted to USD. Packs are priced on total milligrams. Listings sold per kit, per ml, as capsules or sprays, as blends, or without a stated mass are shown but not ranked.
Population
Active online research vendors only. Clinic, pharmacy and telehealth prices are excluded. Medians and the p25–p75 band are computed over comparable listings, one row per vendor product and size.
Independence. Ranking in this index: 0 paid placements.
PeptideBase accepts no payment for inclusion in this index.
