GHK-Cu 75mg Peptides
Elevate formulation work with a peptide standard designed for clarity, control, and consistent performance in the lab.
Peptide Scientific Labs GHK-Cu comes as a lyophilized peptide vial for research and cosmetic formulation development, offering a clean, lab-ready format with a total strength of 75mg per vial. This unfragranced, neutral presentation supports accurate weighing, clean reconstitution, and reproducible screening, whether you are building prototype topicals or conducting bench-level assessments.
Active Ingredient
- Each vial contains 75mg of GHK-Cu, a copper-binding tripeptide widely studied in cosmetic science for its role in supporting collagen-related pathways, improving the look of firmness and tone, and promoting a healthier-looking skin matrix in research models.
The lyophilized format is engineered for stability and precise handling, allowing researchers to control concentration and solvent systems according to protocol. When reconstituted with a suitable laboratory diluent, the peptide integrates smoothly into screening workflows, facilitating dose–response evaluations, compatibility checks with excipients, and iterative formulation refinement. Its straightforward, lab-first presentation is intended to minimize variables so results reflect the peptide and your process—not unwanted additions.
Use cases include exploratory formulation, in vitro and ex vivo assay development, benchtop stability checks, and early-stage prototype testing where disciplined inputs and reliable peptide identity are essential. This vial is designed for teams who value traceable materials, consistent handling characteristics, and a research-focused profile that aligns with rigorous development practices.
Safety, Quality, and Trust
Peptide Scientific Labs operates with an uncompromising focus on purity, consistency, and documentation. Each batch is produced and handled under controlled conditions in the USA and is independently tested for identity and purity to support data integrity and reproducibility. Product packaging is designed to protect the material from moisture and light during routine laboratory storage and handling. For best results, reconstitute using appropriate sterile technique and follow your institution’s protocols for handling, storage, and disposal of research peptides.
For laboratory research and cosmetic formulation development only. Not for human consumption, injection, or clinical use. Keep out of reach of children and untrained personnel.

Frequently Asked Questions
What is GHK-Cu typically studied for?
Researchers most often study GHK-Cu for collagen-related signaling, dermal remodeling, wound repair, extracellular-matrix regulation, and cosmetic-science applications. It is commonly discussed where skin quality and tissue regeneration overlap, but the compliant wording is still that these are research interests, not approved cosmetic or medical claims.
What is GHK-Cu?
GHK-Cu is a copper-binding tripeptide, short for glycyl-L-histidyl-L-lysine copper. It is one of the most recognized peptides in skin and wound-healing research because copper binding changes its biological activity. On a research website, it should be described as a laboratory peptide studied for repair and remodeling pathways.
How do peptides relate to collagen?
Collagen itself is a large protein built from long polypeptide chains of amino acids — primarily glycine, proline, and hydroxyproline — organized into a characteristic triple-helix structure. Shorter peptides enter collagen research in two main ways: as signaling peptides studied for their ability to influence collagen expression in fibroblast models, and as carrier peptides that deliver cofactors relevant to collagen synthesis, such as copper.
So peptides and collagen are not the same thing, but they are biochemically related. Peptides are studied as small informational molecules that interact with the cellular machinery responsible for producing collagen, which is itself a much larger structural protein.
What is the difference between signal, carrier, and neurotransmitter peptides?
Signal peptides are short sequences studied for their ability to mimic fragments of larger proteins and trigger downstream responses in cell models — for example, fibroblast responses relevant to extracellular matrix research. Carrier peptides are studied primarily for their ability to transport trace elements or cofactors, such as copper, into cell systems. Neurotransmitter-modulating peptides are investigated in models of neuromuscular signaling and, in cosmetic-adjacent research, sometimes as structural analogs of botulinum-like sequences.
These are research classifications, not therapeutic categories. All of them are studied in vitro, and the distinctions reflect mechanism-of-action hypotheses rather than any approved clinical use.
What are cosmetic peptides?
Cosmetic peptides are short chains of amino acids studied for their interactions with pathways relevant to skin biology — including collagen expression, extracellular matrix assembly, pigmentation signaling, and barrier function. They are commonly grouped into signal peptides, carrier peptides, enzyme-inhibitor peptides, and neurotransmitter-modulating peptides based on their research mechanism of action.
In a research context, cosmetic peptides are investigated as model ligands for fibroblast response, in vitro wound-healing assays, and skin-equivalent models. The compounds offered by Peptide Scientific Labs in this category are lyophilized research materials intended solely for controlled laboratory investigation and are not cosmetics, drugs, or consumer products.
