GHK-Cu Capsules
GHK-Cu Capsules contain the copper-binding tripeptide complex Gly-His-Lys-Cu2+ in a dry capsule format for laboratory research. This product record focuses on capsule count, labeled material amount, excipient information, and applicable analytical documentation. The base GHK-Cu page provides broader compound identity and research context.
For research use only. Not for human or animal use.
Capsule format and product specifications
The current product record identifies 60 capsules with 2 mg of GHK-Cu per capsule, for 120 mg of labeled GHK-Cu across the container. Each capsule also contains 50 to 200 mg of microcrystalline cellulose as an excipient. These values describe the supplied package and are not a research protocol or recommendation.
The underlying GHK-Cu material is identified by the following specifications:
- Sequence: Gly-His-Lys complexed with Cu2+
- Molecular formula: C14H22CuN6O4
- Molecular weight: 401.91 g/mol
- PubChem CID: 73587
- Presentation: 60 capsules in the current product package
- Shelf-life specification: 36 months when stored according to the current product record
- Minimum purity specification for the underlying capsule material: at least 98.5%
Capsule products receive purity testing under the current testing program. The most recent applicable COA provides the batch-specific analytical result.
Research context for the underlying GHK-Cu material
GHK-Cu is a tripeptide-copper complex studied in cell-based models. A 1988 fibroblast-culture study reported changes in collagen synthesis under the experimental conditions used. That finding concerns the underlying compound in a controlled cellular model. It does not establish a separate result for the capsule package or support a direct cosmetic, anti-aging, recovery, or personal-health claim.
GHK-Cu Capsules, GHK-Cu Spray, and the base powder product share the same underlying compound identity, while each product record provides the specifications for its supplied format. Research findings for GHK-Cu relate to the compound and experimental model rather than to the packaging format.
Certificates of Analysis and related formats
Available COAs are public. GHK-Cu Capsules may reference the analytical documentation for the underlying tested GHK-Cu material rather than a separate capsule-specific COA. The report should be matched to the current material and lot. Professional pricing requires an approved account and login.
Related records include the base GHK-Cu Copper Peptide product and GHK-Cu Spray, each with its own format-specific specifications.
