GHK-Cu (copper tripeptide-1) is a naturally occurring copper-binding tripeptide, glycyl-L-histidyl-L-lysine bound to copper(II), and one of the most studied copper peptides in regenerative and dermatological research. CAS 49557-75-7; molecular formula C14H22CuN6O4; molecular weight approximately 403.9 g/mol; sequence Gly-His-Lys (Cu2+); supplied lyophilised at ≥99% by HPLC. For laboratory research use only.
Isolated from human plasma nearly half a century ago, GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine complexed with copper(II)) that has become one of the most studied small peptides in skin-regeneration and copper-homeostasis research. Its characteristic blue-green colour is the visual signature of the copper ion held within the histidine-lysine coordination site.
A signalling molecule discovered in human blood. The parent tripeptide was first identified in 1977, when researchers traced a growth-modulating activity in human serum to a single small molecule, glycyl-histidyl-lysine (Schlesinger et al., 1977). Early work showed it could influence the behaviour of cultured cells (Barra et al., 1987), and decades of subsequent investigation reframed GHK-Cu as a copper-delivery peptide that interacts with a broad set of cellular pathways (Pickart et al., 2015).
What the research explores. Rather than acting on one isolated target, GHK-Cu has been examined across several overlapping themes in experimental models:
The findings summarised here derive from in-vitro, cell-culture, and animal studies; they describe biological activity observed under laboratory conditions and do not establish efficacy or safety in humans. Full citations are listed under the Scientific References tab.

GHK-Cu is a naturally occurring copper-binding tripeptide, glycyl-L-histidyl-L-lysine complexed with copper(II), originally isolated from human plasma. It is one of the most studied small peptides in skin-regeneration and tissue-repair research. Condor supplies it strictly as a Research Use Only reference compound for in vitro and animal studies.
Both are copper-binding tripeptides, but they differ by one amino acid: GHK-Cu is glycyl-histidyl-lysine and AHK-Cu is alanyl-histidyl-lysine, each complexed with copper(II). GHK-Cu is the more extensively studied in skin and tissue-repair research. They are offered as distinct reagents for comparative copper-peptide studies, research use only.
Yes, the copper matters. GHK-Cu is the tripeptide bound to copper(II), the form in which much of its skin-regeneration and tissue-repair biology has been characterized. The copper-free peptide (GHK) lacks the bound metal central to that activity. This product is the copper(II) complex, supplied for research use only.
Yes. The GHK-Cu component in the GLOW and KLOW blends is the same 50 mg copper(II) tripeptide as the standalone vial, co-formulated with other peptides rather than supplied alone. Choose the standalone to study GHK-Cu in isolation, or a blend to investigate it alongside BPC-157 and TB-500. Research use only.
Yes. Condor Research supplies GHK-Cu strictly as a Research Use Only (in vitro) reference compound to professionals and institutions, not as a cosmetic, supplement or product for human use. Buyers are responsible for confirming import legality in their own country. Questions: info@condorresearch.com.
Yes. Each GHK-Cu batch is tested by an independent third-party laboratory by HPLC for identity and purity (>=99%) and ships with a lot-specific Certificate of Analysis. To request the COA, including how copper content for the batch is documented, contact info@condorresearch.com before ordering.
Yes. A blue color is expected and characteristic of the copper(II)-tripeptide complex; it indicates the bound copper, not contamination. GHK-Cu is reconstituted in water for laboratory preparation (listed solubility 1 mg/mL). This is a research-use-only reagent; reconstitution is for in vitro and animal work, never human or veterinary use.
For laboratory preparation, adding 50 mL of water to the 50 mg vial gives a 1 mg/mL solution (the listed solubility reference); scale the volume for other concentrations. Store the sealed vial at -20C, protected from light; shelf life is 24 months. For research preparation only, not human or veterinary use.
This GHK-Cu has the molecular formula C14H24CuN6O4 and a molecular weight of 403.92, with sequence Gly-His-Lys complexed with copper(II) (CAS 49557-75-7). Identity and purity (>=99%) are confirmed by HPLC on each batch and documented in the lot-specific Certificate of Analysis.
No. The copper is chemically bound within the GHK-Cu tripeptide complex and the product ships as a sealed lyophilized research reagent, declared truthfully as Research Use Only material with correct customs classification and value. Buyers remain responsible for import rules in their own country. Questions: info@condorresearch.com.
If a vial arrives damaged or non-conforming, notify info@condorresearch.com ideally within 48 hours with photos, and a replacement, reshipment or store credit can be arranged. Note that a blue solution after reconstitution is normal for this copper complex. Each batch is independently HPLC-tested at >=99% with a Certificate of Analysis.
Solubility and stability were as described. Knocked one star only because express shipping options are limited, but quality is not in question.
Third order with Condor. Batch-to-batch variation is minimal, which matters for our longitudinal work. The mono-labelled vials are easy to track.
No marketing fluff — just characterised material with paperwork. The data sheet and CAS matched our records precisely.
Lyophilised cake was uniform and dissolved fully. Would appreciate a digital COA portal, but the PDF on request worked fine.
Identity by MS confirmed in our facility. Communication around storage and handling was precise and professional.
