Copper-binding tripeptide complex, sold for laboratory research.
Identity
GHK-Cu is a naturally occurring three-amino-acid fragment, glycine, histidine, and lysine, that binds to a copper atom, and it's already present in human blood, saliva, and urine. The amount of it in the body is reported to drop as people get older, which is part of why researchers got curious about it decades ago. It has been formulated into wound dressings and marketed skin creams for years under the name copper tripeptide-1.
GHK-Cu is a copper-binding tripeptide complex of 3 amino acid residues. SBz Industries sells it for laboratory research.
Research
In plain terms, with a link to every study. The most useful thing to notice is what each study was done in.
GHK-Cu has one of the longer research trails of any peptide in this category, running from lab dish experiments to a human clinical trial on facial skin. A 2018 review pulled together a wide range of that work, describing effects reported on skin cells, wound tissue, and gene activity across many separate small studies. Even so, most of the human-facing research has focused narrowly on skin appearance rather than broader use in the body.
review2018
A 2018 review gathered decades of lab dish, tissue, and animal research on GHK-Cu, first described by the same lead author, describing reported effects on skin cell activity, collagen and elastin production, and tissue repair across skin, lung, bone, liver, and stomach lining.

people2006
Thirteen patients who had laser skin resurfacing on their face were randomly assigned to a skin care regimen with or without a topical GHK-Cu product, and researchers measured redness by computer analysis and blinded reviewers, plus skin appearance by patient questionnaire, over twelve weeks; objective measures showed no difference between groups, though patients using GHK-Cu rated their own results higher.

Handling
Lyophilized: -20C, protected from light. Reconstituted: 2-8C.
Give the vial twenty minutes on the bench before opening it, so water does not condense onto the powder.
Slowly, down the inside wall of the vial, never straight onto the powder.
Leave it alone until it clears. Do not shake it. Shaking damages the peptide.
Once mixed, it breaks down much faster than the dry powder. Keep it cold and dark.
Documentation
An independent lab tests every compound we sell. It confirms the compound is what the label says and measures purity by HPLC.

Both. It has been tested in lab dish and animal tissue work, and in at least one small human trial on skin after laser resurfacing, involving 13 patients.
Yes. It is a naturally occurring peptide fragment found in blood, saliva, and urine, and the amount present is reported to drop with age.
GHK-Cu ships as a freeze-dried powder. Mix it with bacteriostatic water, added slowly down the inside wall of the vial, and let it dissolve without shaking. The researcher decides the working concentration, not us, and we publish no protocols.
Lyophilized: -20C, protected from light. Reconstituted: 2-8C. Vials ship in plain outer packaging with no product name on the outside.
Yes. An independent lab tests every compound: it confirms the compound is what the label says and measures purity by HPLC. The latest certificate is on the product page, and you can read it before you order.
Researchers and institutions, 21 or over. By ordering you confirm the material is for laboratory research and will not be used in humans or animals.
