GHK-Cu Topical Ampules
GHK‑Cu Cosmetic / Topical Ampules is a cosmetic‑grade copper peptide formulation presented as 5 large ampules totaling 1 g, designed for topical and cosmetic formulation use. GHK‑Cu (glycyl‑L‑histidyl‑L‑lysine copper complex) is a well‑characterized tripeptide complex originally identified in human plasma and widely studied in scientific literature for its physicochemical properties and interaction with skin‑relevant biochemical pathways. This formulation is intended for cosmetic, topical, and formulation research applications, where consistency, purity, and stability are required, and is supplied in sealed ampules to support controlled handling and dosing during product development.
Ceritide Research offers GHK-Cu Topical (Copper Tripeptide-1 / Glycyl-L-Histidyl-L-Lysine Copper) as a premium 1g lyophilized research peptide with verified ≥99% purity confirmed by independent HPLC and mass spectrometry. Supplied in a sterile vial and ready for immediate reconstitution per your protocol, this product delivers the reliability top research labs demand.

Peptide Storage Guidelines: Best Practices for Research Stability
At Ceritide Research, we provide high-purity peptides for laboratory and scientific research. Proper storage preserves peptide integrity and supports reliable experimental results.
Storage Guidelines for Lyophilized (Powder) Peptides
- Long-Term Storage: Keep at -20°C (-4°F) or lower (ideally -80°C / -112°F) for multi-year stability.
- Short-Term Storage: Refrigerate at 2–8°C (36–46°F) for weeks to a few months. Minimize room temperature exposure.
- Best Practices: Store in airtight vials with desiccants. Allow vials to reach room temperature in a desiccator before opening. Protect from light and moisture. Aliquot to reduce freeze-thaw cycles.
Storage Guidelines for Reconstituted Peptide Solutions
Once dissolved, peptides are less stable and should be used promptly:
- Recommended Temperature: Store at 2–8°C (36–46°F) (refrigerator) for short-term use, typically up to 1–4 weeks depending on the sequence and buffer.
- Longer-Term Solution Storage: Aliquot and freeze at -20°C (-4°F) or lower. Avoid storing solutions long-term when possible.
- Best Practices: Use sterile techniques, bacteriostatic water or research-grade buffers, and minimize exposure to air and light. Prevent repeated freeze-thaw cycles.
For Research Use Only
