GHK-Cu

Lyophilized (Dry Powder) — Unopened Vials
Unopened lyophilized vials should be stored away from direct light and heat. For use within a few weeks, room temperature storage is acceptable. For storage over several months, refrigeration at 2–8°C (36–46°F) is recommended. For long-term storage, freezing best preserves peptide integrity.

When removing a vial from frozen storage, allow it to reach room temperature before opening to prevent condensation from introducing moisture into the vial.

Reconstitution
Reconstitute using bacteriostatic water (BAC). Inject the solution slowly down the inside wall of the vial rather than directly onto the peptide cake. Gently swirl until fully dissolved; do not shake. Vigorous shaking may cause foaming and mechanical stress to the peptide structure.

Reconstituted Vials
After reconstitution, store vials refrigerated at 2–8°C (36–46°F) and protected from light. Always use clean, sterile technique when accessing the vial to minimize contamination.

With proper refrigerated storage and aseptic handling, reconstituted peptide solutions commonly remain stable well beyond the frequently cited 28-day guideline, which pertains to the antimicrobial effectiveness of bacteriostatic water rather than the intrinsic peptide stability. Many researchers maintaining consistent sterile technique report usable stability in the 60–90 day range under controlled conditions.

General Guidelines

• Keep vials away from excessive heat and prolonged light exposure.
• Do not freeze after reconstitution.
• Discard any solution showing cloudiness, discoloration, or visible particulate matter.
• Label vials with the reconstitution date for tracking purposes.

Study 1: The Human Tripeptide GHK-Cu Stimulates Collagen Synthesis and Tissue Remodeling

Authors: Pickart L., Thaler M.
Source: Journal of Biomaterials Science

Scientific Findings
This early investigation examined the biological activity of the copper-binding peptide GHK-Cu in connective tissue models. Researchers observed increased collagen production and enhanced extracellular matrix remodeling following exposure to the peptide. The findings suggested that GHK-Cu functions as a signaling molecule influencing structural protein synthesis involved in tissue organization.

The study helped establish GHK-Cu as a regulator of tissue remodeling processes through modulation of cellular signaling pathways associated with repair and maintenance mechanisms.

Plain English Interpretation
Scientists found that GHK-Cu encouraged cells responsible for structural support to produce more collagen and reorganize surrounding tissue. These results helped researchers understand how the peptide may participate in natural tissue maintenance and repair processes studied in laboratory models.
