What it is
Pal-GHK is GHK with a 16-carbon palmitoyl chain on its N-terminus. The chain makes it lipophilic, which suits skin-penetration and formulation research.
What researchers study
- Studied as a matrikine: a small fragment of matrix protein that signals fibroblasts to make collagen in culture.
- One of the two peptides in Matrixyl 3000.

How each lot is tested
Samples from every lot go to an independent, ISO/IEC 17025 accredited lab. Its report covers three tests:
- Purity by reversed-phase HPLC: the main peak's share of the total peak area.
- Identity by mass spectrometry: the observed mass should match the expected 578.8 g/mol.
- Endotoxin, measured for every lot.
The lot number on your vial is the number on its report. How to check a certificate of analysis walks through what to look for.
The amount on the label is the weight of the powder. Besides the peptide it includes counter-ions and some water; Purity vs. peptide content explains the difference.
Storage and handling
Store unopened vials at 2 to 8 °C, away from light, as printed on the label. Let a cold vial reach room temperature before you open it, so moisture doesn't condense on the powder. More bench habits are in Handling.
