GHK-Cu 1g Ampules
GHK-Cu is a naturally occurring copper-binding tripeptide composed of glycine, histidine, and lysine, first isolated from human plasma. Its strong affinity for copper(II) forms a stable complex that has made it one of the most extensively studied copper peptides in dermal and tissue repair research. A substantial body of biochemical and cell biology literature has examined this compound.
Each ampule ships with 1g of raw lyophilized GHK-Cu powder sealed for research use, backed by Phantom Peptides' internal verification standard: independent third-party lab analysis.

Research Background
The existing literature on GHK-Cu spans a handful of distinct research threads:
- Dermal fibroblast research: cell culture studies on collagen, elastin, and glycosaminoglycan synthesis in skin fibroblast models
- Wound healing research: studies examining the peptide's role as a chemoattractant for inflammatory and endothelial cells during tissue repair processes
- Copper transport and chelation research: biochemical studies on copper(II) binding affinity and downstream cellular copper delivery mechanisms
- Oxidative stress and antioxidant research: cellular models examining superoxide dismutase upregulation and reduction of oxidative damage
- Angiogenesis research: studies on the peptide's involvement in blood vessel growth signaling
- Comparative peptide research: GHK-Cu examined alongside other copper-binding and repair-associated peptides in cell-based studies
GHK-Cu was first identified through plasma protein research, with the deepest body of published work coming out of dermatology, wound healing, and copper biochemistry research groups. For primary sources, PubMed (pubmed.ncbi.nlm.nih.gov) and NIH's PMC database (pmc.ncbi.nlm.nih.gov) index the peer reviewed literature on GHK-Cu and copper peptide research.

- Real support. Questions about an order or a document? Our team answers from Charleston, SC.
Storage
Before reconstitution
Store the lyophilized powder at or below 8 °C in a dry place, away from light. For long-term storage, keep it frozen at −20 °C.
After reconstitution
Refrigerate at 2–8 °C and use within 30 days. For longer preservation, aliquot and freeze at −20 °C, and avoid repeated freeze–thaw cycles.
Shipping
Orders ship from Charleston, SC with tracking on every package. Vials are packed to protect them in transit, and you can check estimated delivery times for your state on the shop page.

Frequently Asked Questions
1. Is GHK-Cu 1g Ampules supplied as a lyophilized powder?
Yes. GHK-Cu 1g Ampules ships as a lyophilized (freeze-dried) powder, which removes moisture and helps keep the compound stable until it is reconstituted for research.
2. What does 99%+ HPLC purity mean?
High-performance liquid chromatography separates a sample into its components. A 99%+ result means the target compound makes up at least that percentage of the measured sample.
3. How should GHK-Cu 1g Ampules be stored before reconstitution?
Keep the sealed vial at or below 8 °C in a dry place, away from light. For long-term storage, keep it frozen at −20 °C.
4. How long is GHK-Cu 1g Ampules stable after reconstitution?
Refrigerated at 2–8 °C, use within 30 days. For longer preservation, aliquot and freeze at −20 °C and avoid repeated freeze–thaw cycles.
5. Is GHK-Cu 1g Ampules intended for human use?
No. GHK-Cu 1g Ampules is sold for laboratory research use only. It is not for human or veterinary consumption, and we do not provide dosage or administration guidance.
6. Where do orders ship from?
All orders ship from Charleston, SC with tracking.
