GHK-Cu Peptide (50mg) for Laboratory Research

Q: How can GHK-Cu be purchased for research use?

GHK-Cu can be ordered directly from this product page by selecting the 50mg vial and adding it to the cart. Checkout is handled online and orders leave the Florida or California facility within 24 hours. Buyers confirm at checkout that they are 21 or older and are acquiring the compound for laboratory research purposes only.

Q: Is GHK-Cu for sale in a 50mg size?

Yes. This listing covers GHK-Cu supplied as a 50mg multi-dose vial of lyophilized powder, finished in the USA. The vial is intended for in vitro and other laboratory applications and is stocked domestically, so no international import step is involved. Availability is reflected in real time on this page rather than by backorder.

Q: Where is the GHK-Cu COA published?

Certificates of analysis are published in the public lab results section of the site, organized by compound and lot number. The certificate for the GHK-Cu lot currently in stock is available there before an order is placed, so identity and purity data from the independent laboratory can be reviewed rather than requested after the fact.

Q: Does GHK-Cu ship with a COA for the exact lot?

Yes. Testing is performed lot by lot by an independent analytical laboratory, not on a single representative batch. The certificate corresponds to the specific GHK-Cu lot being shipped and remains posted publicly, so the reported analytical figures can be matched against the lot number printed on the vial received.

Q: What defines a high-purity GHK-Cu research compound?

Laboratories generally evaluate GHK-Cu on third-party analytical data rather than marketing claims: identity confirmation by mass spectrometry, purity by HPLC, and lot traceability. Published certificates, consistent lot numbering, and a supplier that documents each batch make results easier to reproduce and comparisons between suppliers more meaningful.

Q: How is GHK-Cu priced on this page?

The current price for the 50mg GHK-Cu vial is displayed on this product page and reflects the size selected. Pricing shown at checkout is always the live figure, so published amounts elsewhere may be outdated. Wholesale and multi-item pack options are described in their own sections of the site for laboratories ordering larger quantities.

Q: Where does GHK-Cu ship from, and how fast?

Orders are fulfilled from Real Peptides' United States facilities in Florida and California and are dispatched within 24 hours of being placed on business days. Domestic stock means transit times are short and no customs clearance is required. Tracking details are issued by email once the parcel leaves the warehouse.

Q: How should GHK-Cu be handled on arrival?

Laboratories typically log the lot number against the published certificate, then store the sealed lyophilized vial cold and protected from light and moisture, following the handling conditions noted on the product documentation. GHK-Cu is a research chemical for laboratory use only and is not a drug, supplement, or cosmetic, and is not intended for human or animal use.

GHK-Cu is a copper-chelated tripeptide — glycyl-L-histidyl-L-lysine complexed with copper(II) — synthetically manufactured as an analogue of a sequence first identified in human plasma. In laboratory settings it is used as a reference compound in cell- and tissue-model work on extracellular matrix remodeling, collagen-related signaling, angiogenesis assays, and follicular research.

Real Peptides supplies GHK-Cu as a 50mg multi-dose vial of lyophilized powder, finished in the USA. Every batch is analyzed by an independent laboratory, and the certificate for the current lot is published on the lab results page so it can be reviewed before purchase. Orders ship from the Florida or California facility within 24 hours. Sold strictly for research use only — not for human or animal consumption.

AboutLab reportSpecificationsQuestions

99% Pure | Multi Dose | Finished in the USA

GHK-Cu is a three-amino-acid peptide (Gly-His-Lys) chelated to copper that labs use to investigate collagen remodeling, angiogenesis, and hair-follicle activation in cell and tissue models. It supports studies of skin-firming, wound-closure rates, and follicular health without systemic hormone effects. Each 50 mg vial is HPLC-verified to ≥ 99% purity, endotoxin-screened (< 0.1 EU/mg), and supplied with detailed handling guidelines.

What Is GHK-Cu?

GHK-Cu (Copper Tripeptide-1) is a small, three-amino-acid research peptide (Gly–His–Lys) complexed with a single copper ion. In preclinical and cell-culture models, GHK-Cu serves as a precision tool for studying extracellular matrix remodeling, microvascular growth, and hair-follicle biology. By mimicking natural copper-binding sequences, it supports detailed exploration of collagen synthesis, endothelial signaling, and antioxidant enzyme activation—without engaging systemic hormonal pathways.

Why Choose GHK-Cu?

Researchers turn to GHK-Cu when they need a dual-action peptide that simultaneously drives tissue-repair and oxidative-stress mitigation. Its compact tripeptide structure ensures rapid diffusion into fibroblast, keratinocyte, and endothelial models, while its copper chelate enables robust activation of lysyl oxidase and superoxide dismutase. Manufactured and verified to ≥ 99% HPLC purity with strict endotoxin screening, GHK-Cu delivers consistency and reproducibility—essential for high-impact skin, wound-healing, and hair-regeneration studies.

What Sets GHK-Cu Apart?

Unlike generic copper salts or longer peptide fragments, GHK-Cu uniquely combines copper-mediated enzyme activation with peptide-driven signaling in a single molecule. Its proven ability to upregulate both collagen I/III and VEGF-driven angiogenesis in vitro, plus its potent antioxidant effects in ROS-challenged cultures, makes it an exceptionally versatile research reagent. With demonstrated stability in both lyophilized and reconstituted forms, GHK-Cu stands out as the go-to peptide for labs seeking precise, multi-pathway insights into regenerative and vascular biology.

Research observations

Collagen Synthesis Boost

GHK-Cu increases Type I and III collagen production in human fibroblast assays, modeling skin-repair protocols.

Angiogenic Signaling

In endothelial cultures, GHK-Cu elevates VEGF expression and capillary-tube formation for vascular-growth studies.

Hair-Follicle Activation

GHK-Cu stimulates dermal papilla cell proliferation and hair-shaft thickening in rodent follicle models.

Anti-Inflammatory Modulation

GHK-Cu downregulates pro-inflammatory cytokines (IL-1β, TNF-α) in keratinocyte assays, aiding wound-healing research.

Antioxidant Enzyme Upregulation

Enhances superoxide dismutase (SOD) activity and lowers reactive oxygen species in oxidative-stress models.

Lab-Friendly Prep & Storage

Reconstitute in Sterile Water for Injection (SWFI) or Bacteriostatic Water (BAC); store lyophilized at – 20 °C and reconstituted at 2–8 °C for up to 7 days to maintain ≥ 98% integrity.
