GHK basic

Compound Overview

Research Use Only. Not for Human Consumption.

GHK basic is supplied by Nexus as a 50mg research catalog variant under SKU GH50. The supplied research record identifies GHK basic as the copper-free Gly-His-Lys tripeptide: a free peptide form related to, but analytically distinct from, GHK-Cu.

This page is intentionally limited to the provided Nexus product data and the supplied GHK basic research record. The source data provides core identity fields, storage guidance, and a short research-context note, but it does not provide lot-specific purity, HPLC retention time, mass-found values, batch numbers, COA release dates, assay conditions, reconstitution solvent, or quantitative published-study details. Those values are not inferred.

Research Background & Published Literature

The supplied research overview states that GHK basic is the copper-free Gly-His-Lys tripeptide used as a comparator or formulation component in cosmetic peptide research. Within the provided data, that comparator language is the primary research context for this SKU.

The distinction between GHK basic and GHK-Cu is central to the source record. The provided background note specifically instructs not to reuse GHK-Cu mass data for this product, because the copper-free peptide and the copper complex have different formulae, color, mass, and analytical expectations. Nexus therefore presents GHK basic with its own supplied identity fields and does not borrow copper-complex values from adjacent catalog records or public summaries.

The source record does not provide citation-level literature details such as author names, journal titles, PubMed identifiers, DOI identifiers, experimental endpoints, cell models, concentration ranges, or quantitative assay results. Because those details were not supplied, this section stays at the level of compound identity, comparator use, and documentation boundaries.

The supplied source list includes the following reference materials for background context:

Those source labels are provided here only as the research-record source list. This page does not expand beyond the facts supplied in the Nexus research data.

Researchers reviewing the literature around this compound can use the peer-reviewed resources below for additional context on mechanism of action, signaling pathways, and controlled laboratory research applications:

Storage, Handling & Stability Guidelines

The supplied storage guidance is to store lyophilized GHK basic at -20°C, desiccated and protected from light. After reconstitution, the source data directs laboratories to aliquot the material and avoid repeated freeze-thaw cycles.

• Store sealed lyophilized material at -20°C.
• Keep the material desiccated during storage.
• Protect the compound from light.
• After reconstitution, aliquot the material when compatible with the research workflow.
• Avoid repeated freeze-thaw cycles after reconstitution.

The source record does not specify a reconstitution solvent, working concentration, post-reconstitution expiration interval, vial headspace condition, or formal stability-study period. Those details should be established from current lot documentation or a laboratory-validated protocol, not from extrapolation.

Lab Verification

Nexus maintains research-compound verification records through the Lab Verified archive. In general terms, HPLC verification is used to evaluate chromatographic purity, while MS verification is used to support molecular-identity confirmation where current lot documentation is available.

No exact GHK basic COA values were provided in the current product record. The data does not include a batch number, purity percentage, HPLC chromatogram value, retention time, expected mass, observed mass, release date, or analyst field. Researchers should review the current /lab-verified record and any available COA before incorporating GHK basic into a controlled in-vitro workflow.
