What is PAL-GHK?
PAL-GHK (Palmitoyl Tripeptide-1) is a lipopeptide composed of palmitic acid covalently conjugated to the bioactive tripeptide glycyl-histidyl-lysine (GHK). The palmitoyl modification enhances lipophilicity and dermal bioavailability, making PAL-GHK a widely used research tool for studying collagen biosynthesis, extracellular matrix remodelling, and skin ageing biology. For published research, see PubMed studies on Palmitoyl Tripeptide-1{:target=“_blank” rel=“noopener”}.
PAL-GHK is one of the most extensively studied cosmetic peptides, with demonstrated activity in stimulating fibroblast collagen production and modulating TGF-β signalling pathways.
Best-Peptides supplies research-grade PAL-GHK with guaranteed ≥99% purity and full analytical documentation.
How Does PAL-GHK Work?
Collagen Stimulation
- Type I collagen induction - COL1A1 gene upregulation

FAQ
PAL-GHK (Palmitoyl Tripeptide-1) is a lipopeptide consisting of palmitic acid conjugated to the GHK tripeptide. It is studied for its role in stimulating collagen synthesis, extracellular matrix remodelling, and skin biology, particularly in the context of ageing and wound healing.
PAL-GHK activates fibroblast signalling via TGF-β pathway modulation, promoting type I and type III collagen gene expression. The palmitoyl moiety enhances dermal penetration and cellular uptake compared to unmodified GHK.
PAL-GHK and GHK-Cu both derive from the GHK tripeptide but differ in modification: PAL-GHK uses palmitic acid conjugation for lipophilicity, while GHK-Cu uses copper chelation. Both stimulate collagen but through partially distinct signalling mechanisms.
Store lyophilised PAL-GHK at -20°C for long-term stability. Once reconstituted, keep at 2-8°C and use within 4 weeks. Protect from light.
Our PAL-GHK is ≥99% pure as verified by HPLC. Each batch includes a Certificate of Analysis with purity data and mass spectrometry identity confirmation.
Yes, PAL-GHK is frequently studied in combination with Matrixyl (Palmitoyl Pentapeptide-4), SNAP-8, and GHK-Cu to evaluate synergistic effects on collagen synthesis and extracellular matrix remodelling.
Reconstitute in sterile DMSO for stock solutions due to the lipophilic palmitoyl moiety, then dilute further in aqueous buffer as needed. For aqueous solutions, gentle warming may assist dissolution.
PAL-GHK is available in 1 mg vials, supplied in packs of 10 × 1 mg for research applications.
