GHK-CU Nasal Spray

GHK-Cu is a naturally occurring copper-binding peptide frequently studied in models related to skin repair, cellular aging, and inflammation signaling. In non-human research, it has shown relevance in the regulation of gene expression tied to regeneration, collagen production, and oxidative stress recovery.

The intranasal format allows researchers to investigate non-invasive delivery routes, with particular focus on:

Copper signaling and peptide stability

Central versus peripheral distribution

Systemic gene modulation in non-injection protocols

Comparisons with topical and injectable administration

Each bottle of GHK-Cu Nasal Spray from KÖLD is manufactured in the United States, filled in a sterile environment, and third-party tested to confirm purity, identity, and volume consistency.

1. Why is GHK-Cu studied in nasal spray format?
Intranasal delivery provides a non-invasive route for studying peptide distribution and copper-related gene signaling in systemic and CNS models.

2. Can this spray be used on the skin or taken orally?
No. This product is for research use only. It is not intended for human or animal use and should only be handled in controlled laboratory settings.

3. How long is this spray stable after opening?
It should be stored in the refrigerator and used within 30 days of first use to maintain integrity and sterility.

4. Where is this product manufactured?
All KÖLD nasal sprays are formulated, filled, and tested in the United States under strict laboratory standards.

5. Can this compound be combined with other peptides in study designs?
Yes. GHK-Cu is often studied in combination with BPC-157 or NAD+ in regenerative and anti-aging protocols. Always consult peer-reviewed literature for guidance.
