GHK-Cu in Colombia: identity, regulatory status and presentations

GHK-Cu (GHK-CU in the catalog) is the tripeptide glycyl-L-histidyl-L-lysine bound to copper, which PubChem lists as "Prezatide copper" (CID 71587328), with "GHK-Cu" and "Copper tripeptide-1" among its synonyms. In the query of October 11, 2026, none of the four datasets of Invima's Unique Drug Code (CUM) contained a sanitary registration for GHK-Cu. This catalog offers it exclusively for research. The article gathers sourced facts on its identity and regulatory status, refers to the product page for presentations and storage, and does not substitute for the buyer's own document review.

What GHK-Cu is

PubChem lists GHK-Cu under the title "Prezatide copper" (CID 71587328), with the molecular formula C14H23CuN6O4+. Its synonyms include "GHK-Cu", "GHK copper" and "Copper tripeptide-1", and its chemical name, "[N2-(N-Glycyl-L-histidyl)-L-lysinato(2-)]copper", corresponds to the tripeptide glycyl-L-histidyl-L-lysine bound to copper.

For the tripeptide without copper (glycyl-L-histidyl-L-lysine, CID 73587), PubChem takes this description from ChEBI: "Gly-His-Lys is a tripeptide composed of glycine, L-histidine and L-lysine residues joined in sequence". That is a structure-level description, and this article goes no further than that identification.

In this catalog, GHK-CU is described as the copper tripeptide glycyl-L-histidyl-L-lysine, within the tissue signaling and extracellular matrix group, and is listed as a reference intended exclusively for research. The catalog blends that declare GHK-Cu among their components are separate references, each with its own product page and its own batch documentation.

Regulatory status in Colombia: sourced facts

Invima publishes the Unique Drug Code (CUM) on datos.gov.co in four datasets: current registrations, expired registrations, registrations in other statuses and registrations undergoing renewal. In the query of October 11, 2026, none of the four contained a sanitary registration with GHK-Cu as active ingredient or in the product name, nor with the synonyms PubChem lists ("Prezatide copper", "Copper tripeptide-1"), their Spanish forms or the name of the tripeptide, glycyl-L-histidyl-L-lysine. The rows that mention copper in those datasets correspond to other active ingredients, such as copper salts. September 16, 2026 is the date of the last data update of the four datasets on datos.gov.co. The renewal dataset covers renewals, not new applications, so this query does not support any statement about pending applications. The CUM covers medicines, and this article does not review other Invima registries.

In June 2026, Invima issued at least two health alerts, each originating from a complaint, that include products offered under the name of GHK-Cu. According to the date of their PDF documents, Alert No. 181-2026 is from June 23, 2026 and No. 184-2026 from June 24, 2026. Alert 181 includes a product named "GHK-Cu peptide solution" together with four others, one of them bearing the name of tirzepatide and another the name of retatrutide. Alert 184 includes a product labeled "GHK-CU", followed by a presentation figure that this article does not repeat, together with other products offered under peptide names, among them retatrutide. This list is not meant to be exhaustive.

According to the text of the two alerts, the products named are not covered by any sanitary registration issued by the competent authority, their marketing in Colombia is illegal and they are considered fraudulent products; as the rule breached, they cite Decreto 677 de 1995. The alerts add that, because they do not comply with that rule, the products have not been evaluated for quality, safety or efficacy. They advise the general public to refrain from acquiring them, and tell holding establishments, distributors and sellers to refrain from distributing and marketing them, because marketing them may lead to sanitary safety measures.

The GHK-CU reference in this catalog is offered as a reference intended exclusively for research and, according to the site's sanitary notice (/en/legal/sanitary-notice), the catalog references have no Invima sanitary registration for use in humans or animals. The article "What research grade means for a peptide" explains why that label is not a sanitary registration, and "Importing research peptide supplies into Colombia" describes the difference between importing a supply and importing a drug.

Presentations

The catalogued presentations of GHK-CU and its technical block are on its catalog product page. This article does not repeat them, because they can change.

Storage

The storage conditions declared by the catalog are covered in the article "Storage and transport of research peptides". This article does not repeat them: the current value is the one shown in the technical block of the GHK-CU product page.

Frequently asked questions

What is GHK-Cu?
It is the tripeptide glycyl-L-histidyl-L-lysine bound to copper. PubChem lists it as "Prezatide copper" (CID 71587328), with "GHK-Cu" and "Copper tripeptide-1" among its synonyms. This catalog lists it as GHK-CU and offers it exclusively for research.
Does GHK-Cu have an Invima sanitary registration as a medicine?
In the query of October 11, 2026, none of the four Unique Drug Code (CUM) datasets contained a GHK-Cu registration. The references in this catalog have no sanitary registration for use in humans or animals, according to the site's sanitary notice.
What do Invima's health alerts say about products with GHK-Cu?
Alerts 181-2026 and 184-2026 name products offered under the name of GHK-Cu without a sanitary registration; according to their text, marketing them in Colombia is illegal and they are considered fraudulent.
Where can the presentations be found?
The catalogued presentations of GHK-CU and its technical block are on its catalog product page.
Does this article teach reconstitution or how to apply the material?
No. This site does not publish reconstitution steps or routes of administration. The reference is offered exclusively for research.
