Read the GHK-Cu research guide for scientific background and sources.
GHK-Cu research vials are presented on one page with 50mg, 100mg and 200mg options. Selecting a strength displays its own price, image and availability. Check availability for the selected strength. Each unit is one vial. The mg marking is nominal content, while the illustrated 3ml marking refers to container capacity.
GHK-Cu is the copper complex of the tripeptide Gly-His-Lys and is distinct from the copper-free GHK Basic listing. Published fibroblast experiments have investigated cellular growth and the production of signaling factors following exposure to the copper complex. A 2005 study compared responses in normal and irradiated fibroblasts, providing a specific cell-model context for discussing growth-factor research.
A separate investigation compared GHK, GHK-Cu and copper chloride in relation to TGF-beta secretion in human dermal fibroblasts. Such comparisons help show why chemical form, culture conditions and the endpoint measured matter. They do not establish that the different materials are equivalent in all models or that a research vial produces a clinical skin, hair or wound-healing benefit. The skin-layer motif and research chart are explanatory illustrations.
The gallery retains the existing documents labeled for 100mg material for reference. Those documents do not verify the identity, purity or quantity of the new 50mg or 200mg options, and current-lot matching still requires review. Strength selection changes the offered vial amount and availability, not the evidentiary status of the product. Consult the relevant lot documentation separately from the general educational charts before making laboratory comparisons.
Documentation: Educational COA, chromatography, mass-spectrometry and traceability graphics are not test results for this product. For laboratory research only; not for human or veterinary use, diagnosis or treatment.
