A light, water-based serum built on GHK-Cu: copper(II) held by the tripeptide glycyl-L-histidyl-L-lysine. Scientists first described GHK in human plasma in the early 1970s, recognising it as a stretch matching part of the albumin sequence; its strong pull on copper is what turns the complex a deep blue and what makes it so interesting to researchers. Reports that circulating GHK declines with age help explain why skin and matrix biologists have investigated it so extensively.
An independent laboratory confirms ≥99% HPLC purity for the peptide inputs, and each lot comes with its own certificate of analysis. Made and dispatched from our EU warehouse, strictly for laboratory research.

Questions about GHK-Cu Face Serum
What does the serum contain?
Its sole active is GHK-Cu — glycyl-histidyl-lysine complexed with copper(II) — in a light aqueous base without fragrance or colourant. Two strengths share the same vehicle in a 30 mL bottle: 1% (10 mg/mL) and 3% (30 mg/mL).
Has the peptide in the serum been tested, and is there a COA?
Yes. Our GHK-Cu raw material only goes into production once it meets a ≥99% HPLC specification and its identity has been verified by mass spectrometry; ask us for that lot's certificate whenever you need it. Each bottle's own lot number links your notebook entries to it.
What makes the serum blue?
Copper(II) bound to the tripeptide. When the complex is intact the colour is a deep blue, which gives a fast visual check. A greenish drift or fading points to disruption by reducing agents, rival chelators or an unsuitable pH.
How do I store it?
Preferably refrigerated (2–8 °C), cap screwed tight, out of the light. Don't dip used applicators into the bottle, and note the opening date next to the lot number so your records remain traceable.
Serum or lyophilised powder — which should I use?
Powder lets you design your own vehicle at any concentration; the serum is a finished aqueous formulation at two set strengths. Groups studying formulations or skin models tend to choose the serum, whereas those characterising the complex itself usually begin with powder.
