Test of Copper Peptide GHK-Cu Powder

What Is GHK-CU Powder?

Copper Peptide GHK-Cu powder is a small bioactive complex. It is formed when the tripeptide GHK (glycine-histidine-lysine) binds with copper ions (Cu²⁺). It is widely used in skincare, biomedicine, and hair care. At the molecular level, the GHK peptide binds stably with Cu²⁺ through the nitrogen atom in the histidine side chain. This forms a stable coordination complex. Its molecular formula is C₁₄H₂₂CuN₆O₄. Its molecular weight is 404.04 Da. Its CAS number is 89030-95-5.

Unlike free GHK white powder, GHK-Cu Copper Peptide Powder is a blue to blue-purple crystalline powder. Its water solution is clear sky blue. Color uniformity is an important indicator of purity and stability. If the powder is white or the solution becomes cloudy, it may indicate degradation or copper dissociation, and reduced effectiveness.

With a molecular weight of about 400 Da, GHK-Cu is a small peptide. Copper Peptide GHK-Cu powder can penetrate the skin barrier and reach the dermis. This is a key advantage compared with large-molecule peptides and collagen, which have limited skin penetration.

How To Store GHK-Cu Powder?

GHK-CU blue copper peptide powder's copper chelate structure is susceptible to dissociation and inactivation due to temperature, light, and moisture.

• Storage stability (unopened)

GHK-Cu blue copper peptide powder has a copper chelate structure that is sensitive to temperature, light, and moisture. Unopened, vacuum-sealed copper peptide GHK-Cu powder should be stored at -20°C in a dark, airtight, and moisture-free environment. It can maintain stable color, purity, and activity for up to 24 months. At room temperature in a sealed, dark place, it remains stable for about 12 months.

• Handling after opening

Once opened, exposure to moisture and oxygen can speed up degradation. The product should be kept at room temperature in a dark place and used within one month. Open and close the container quickly, and reseal it tightly immediately after sampling copper peptide GHK-Cu powder to reduce air exposure. Avoid heat above 40°C, direct sunlight, and high humidity.

• Compatibility and sample handling

Do not store with strong acids, strong oxidants, EDTA, or iron/zinc materials, as they may cause copper ion release. For small 10g copper peptide GHK-Cu powder samples, repackage into light-proof, sealed cryogenic tubes. This reduces repeated exposure and helps maintain stability and activity.
