GHK-Cu 100mg Peptides
Precision begins at the molecular level—and this vial is designed for researchers who demand it.
Better Molecule GHK-Cu is a lyophilized peptide vial featuring Copper Tripeptide-1 (GHK-Cu) in a clean, freeze-dried format for controlled laboratory work. This cosmetic-research peptide is supplied as a single-vial presentation with a total content of 100mg to support consistent preparation, aliquoting, and assay development across studies.
- Each vial contains 100mg of GHK-Cu, a copper-binding tripeptide widely studied in cosmetic and peptide research for its role in extracellular matrix signaling and metal ion transport in controlled laboratory models.
As a non-edible, laboratory-format compound, this lyophilized presentation enables careful reconstitution and precise dosing workflows. Researchers can evaluate solubility profiles, stability, and protocol-specific dilutions with confidence, while maintaining clarity around concentration and lot identity. The neutral, unflavored powder format helps reduce variables unrelated to the study objective, keeping the focus on the integrity of the peptide itself.
Every vial reflects Better Molecules disciplined approach to quality. We source with intention, handle with care, and maintain rigorous controls to protect peptide integrity from receipt through fulfillment. Each lot is analytically tested for identity and purity, and documentation is available to support method development and recordkeeping needs. Packaging and labeling are designed for professional lab environments, with clear strength notation and straightforward presentation.
Better Molecule operates from the USA with a focus on reliability, transparency, and consistency.

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 Better Molecule in this category are lyophilized research materials intended solely for controlled laboratory investigation and are not cosmetics, drugs, or consumer products.
