Lyophilized form helps protect peptide quality. Peptides are supplied as a dry powder, which may look like a compact "puck" or a lighter powder inside the vial.
Because the peptide is dry, it does not require refrigerated shipping during normal transit, including warm seasonal conditions. For longer storage, follow the storage guidance in the product description.
Appearance can vary. The stated peptide content is checked through third-party analysis.

Solution not bundled
Peptides are delivered as lyophilized powder. This dry form helps preserve peptide quality during storage and transport and does not require refrigerated shipping during normal transit.
To prepare a solution, use a solvent such as Bacteriostatic water. It is sold separately, so add it only when you need it for peptide preparation.

Research overview
GHK-CU
GHK-Cu combines a defined three-amino-acid peptide with copper. Its complex form, copper binding, and analytical identity matter when studies are compared.
Studies cover matrix-related cell work, microbial tests, nervous-system models, and gene activity. They provide research context, not a promised result for this material.
Copper binding and matrix models
Studies measure copper binding, fibroblast activity, collagen markers, and extracellular-matrix signals. These topics support controlled chemistry and cell-culture work.
Gene-expression studies must be read with their exact tissue, timepoint, and test method.
Microbial and neural research
Other studies use microbial tests and nervous-system models. These model types should be read separately instead of combined into one broad claim.

Handling
Peptides in transport
Peptides in lyophilized form are supplied in glass vials by standard shipping methods and do not require refrigeration. Short-term temperature fluctuations during transport will not reduce their quality and efficacy. Even at high summer temperatures, the peptides in lyophilized form are stable for several weeks.
Storage of lyophilized peptides
Lyophilized peptides should be stored in a dry place, protected from light and moisture. The following storage conditions are generally recommended:
Room temperature (15–25 °C): Up to 3 months
Refrigerated (2–8 °C): Up to 6 months
Frozen (-20 °C or below): 3–5 years (recommended for long-term storage)
Allow the vial to reach room temperature after taking it out of the refrigerator or freezer.
Storage of reconstituted peptides
Once reconstituted, peptide solutions are generally less stable than their lyophilized form and should be stored under refrigerated conditions whenever possible.
The following storage conditions are generally recommended:
Room temperature (15–25 °C): Avoid prolonged storage
Refrigerated (2–8 °C): Typically 4–8 weeks
Frozen (-20 °C or below): Up to 3–4 months
To preserve peptide integrity, avoid repeated freeze–thaw cycles, as these may accelerate peptide degradation.
Important: Most manufacturers recommend discarding reconstituted peptides within 4 weeks when stored at 2–8 °C. This recommendation is intentionally conservative and may not reflect the actual chemical stability of every peptide. In our own stability studies, many peptides reconstituted in bacteriostatic water showed no detectable degradation after 12 weeks of refrigerated storage. As peptide stability is highly sequence- and formulation-dependent, this result should not be extrapolated to all peptides without supporting stability data.
