Buy GHK-Cu Research Compound.
GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is one of the most researched cosmetic and wound-healing peptides. This guide covers sourcing GHK-Cu for research — specifications, quality evaluation, and documentation requirements.
What is GHK-Cu?
GHK-Cu is a naturally occurring copper peptide complex found in human plasma, saliva, and urine. It consists of the tripeptide glycyl-L-histidyl-L-lysine (GHK) complexed with copper(II) ions. Research has documented its effects on wound healing, collagen synthesis, fibroblast proliferation, anti-inflammatory pathways, and tissue remodeling. GHK-Cu has been studied extensively in dermatological and regenerative medicine research.
GHK-Cu supplied by B&H Bio is a research compound for laboratory evaluation only. It is not for human consumption.

| Form | Lyophilized powder | Stable for storage and shipping |
| Appearance | Blue to blue-green powder | Characteristic copper complex color |
How to evaluate GHK-Cu quality
- HPLC purity ≥ 99%Quantified purity by HPLC. The COA must state the exact percentage — "passes" without a number is insufficient.
- Copper complexation verificationThe copper-to-peptide ratio should be 1:1. Incomplete complexation produces a mixture of free peptide and copper salt, which behaves differently in research.
- Appearance verificationGHK-Cu has a characteristic blue-blue/green color due to the copper complex. White powder suggests the copper is absent — this would be free GHK peptide, not GHK-Cu.
- Endotoxin testingLAL assay results reported on COA for in vitro and in vivo research.
- Lot traceabilityEach batch linked to its COA via unique lot number.
GHK-Cu storage and handling
-20°C storage
Store at -20°C in a sealed, light-protected container. Stable for 24+ months under proper conditions.
2-8°C storage
After reconstitution, store at 2-8°C. Use within supplier-recommended timeframe. Avoid freeze-thaw cycles.
Protect from light
The copper complex is light-sensitive. Store in amber vials or foil-wrapped containers.
