about the
GHK-Cu 100pen
GHK-Cu is a copper-binding tripeptide, supplied in a 3 mL / 300-click pen for skin, collagen and cellular research.
Certificate of analysis"Counted my clicks, done in ten seconds. No syringes, no unit maths, the dosing card lives on my desk now."
"Checked the batch number against the public COA before first use, matched to the decimal. That's why I switched."
"Arrived cold, packed like something precious. Temperature strip still green on arrival. Genuinely impressed."
why a pen beats
a vial & syringe
Traditional research peptides arrive as lyophilised powder that must be reconstituted, drawn into insulin syringes, and converted from milligrams to units by hand, every step a chance for a dosing error.
A multi-dose pen removes the whole failure chain. The peptide arrivesalready dissolved and calibrated. Attach a fresh needle, turn the dial until you count your clicks, and you're done, the same audible-click mechanism trusted in insulin and GLP-1 pens worldwide.
Pens travel and store better, too: no open vials, no bent needles, no septum contamination after repeated draws. One sealed barrel, ten sterile needles, one dosing card.
how to buy
peptides safely
The peptide market has a purity problem: independent surveys routinely find underdosed, mislabelled or contaminated product sold online. The only reliable defence isthird-party verification you can check yourself, not a supplier's own claims.
Before buying any peptide pen, ask three questions. Is every batch tested by an independent lab? Is the certificate of analysis available, so you can check your exact lot before first use? And does it ship cold-chain, insulated and gel-packed, so what was tested is what arrives?
Veyvora answers yes on every order, independent assay, a COA on request against the batch number, and cold dispatch within 24 hours, paperwork packed inside.

GHK-Cu 100 mg Pen: Product Identity and Scope
The GHK-Cu 100 mg Copper Peptide Research Pen is a multi-dose laboratory device pre-filled with glycyl-L-histidyl-L-lysine copper(II) complex, PubChem CID 23724905, molecular formula C₁₄H₂₂CuN₆O₄, presented in a 3 mL, 300-click pen format with a labelled total fill of 100 mg, supplied strictly for in-vitro research use only and not as a prescription, pharmacy or consumer product [1].
GHK-Cu carries no MHRA authorisation and does not appear as an EMA-authorised active substance as of 2026 [2], so any pen labelled for laboratory use is a research chemical rather than a licensed medicinal product. The labelled milligram quantity must not be interpreted as a clinical dosing schedule or as evidence of human skin outcomes.
The 100 mg total fill, 3 mL volume and 300-click count define the pen’s standard format. Every pen ships with an independent, batch-specific certificate of analysis (CoA) from Asterion Analytics, so the compound’s identity and HPLC purity are recorded for the exact lot; researchers should follow the process for matching a CoA to your pen to confirm that the batch number on the physical device corresponds to the analytical record.
Verified Specifications
GHK-Cu (glycyl-L-histidyl-L-lysine copper(II) complex, PubChem CID 23724905, molecular formula C₁₄H₂₂CuN₆O₄) is the active substance in the Veyvora research pen. The specification fields below describe the pen’s standard format; the identity and HPLC purity of each batch are confirmed on the independent, batch-specific CoA that ships with every pen.
Specification table
| Parameter | Value | Verification status |
|---|---|---|
| Active substance | GHK-Cu (PubChem CID 23724905) | Confirmed, authoritative chemical record |
| Molecular formula | C₁₄H₂₂CuN₆O₄ | Confirmed, authoritative chemical record |
| Total labelled fill | 100 mg | Confirmed on the batch CoA |
| Fill volume | 3 mL | Pre-filled solution |
| Click count | 300 clicks | Fixed pen format |
| Calculated quantity per click | ~333.3 µg (100 mg ÷ 300) | Arithmetic only; not a measured assay result |
| Solvent / excipients | Aqueous solution | Per current SDS |
| Sterility / endotoxin | Reported on the batch CoA | Per-lot analytical record |
| Appearance | Solution (pre-filled pen) | Per current label |
The per-click arithmetic (approximately 333.3 µg) is a labelled-quantity calculation, not a measured batch result, and must not be used as a dosing reference for any human or animal application. Each pen ships with its batch-specific CoA; researchers can also request the safety data sheet (SDS) from Veyvora and should consult the storage and handling guidance before working with the pen in a laboratory setting.
Batch Documentation and Analytical Evidence
Every Veyvora GHK-Cu 100 mg pen ships with an independent, batch-specific certificate of analysis (CoA) from Asterion Analytics, reporting the compound’s identity by LC-MS, its HPLC (high-performance liquid chromatography) purity against a ≥ 98.0% specification, and a safety panel that includes an endotoxin result. Veyvora then verifies each batch again with its own internal testing before release. The CoA is tied to the lot number printed on the pen, so it describes your exact material; match your batch to it before any laboratory work begins.
What the certificate covers
A CoA carries analytical weight because it is specific to the lot number printed on the pen itself. The Veyvora CoA references that exact batch, names the testing laboratory (Asterion Analytics), states the analytical method (HPLC for identity and purity, mass spectrometry for molecular confirmation, and a limulus amebocyte lysate (LAL) or equivalent assay for endotoxin), and records the laboratory’s accreditation status. In Great Britain, UKAS (United Kingdom Accreditation Service) accreditation is the relevant benchmark.
Because the Veyvora CoA is issued from an independent laboratory assay and is matched to the batch number, researchers can verify it against the lot printed on the pen. GHK-Cu (PubChem CID 23724905) does not appear as a European Pharmacopoeia monograph substance in the publicly searchable EDQM (European Directorate for the Quality of Medicines) database as of this 2026 pass, which means no Ph. Eur. identity or purity specification exists to serve as an external reference standard; the batch CoA is therefore the primary analytical record. Researchers should record the testing laboratory’s name, accreditation number, and method detection limits alongside any CoA retained for audit purposes.
For guidance on interpreting what analytical testing does and does not establish, see what HPLC purity does and does not prove. Researchers who find that the GHK-Cu pen format does not suit their protocol can browse research peptides by focus to identify an alternative catalogue presentation.
Handling and Storage
The GHK-Cu 100 mg Copper Peptide Research Pen is a pre-filled solution and is dispatched cold-chain. For the recommended storage temperature, reconstituted-stability window and in-pen hold time, consult Veyvora’s current label, SDS and storage and handling guidance before any laboratory work begins.
What to confirm before use
Researchers should confirm the following against Veyvora’s current documentation before use:
- Recommended storage temperature range and whether the pen requires refrigeration or freezing prior to first use
- In-pen stability window once the pen has been activated or punctured
- Light-sensitivity requirements and recommended container type for secondary storage
- Solvent identity for the pre-filled solution and any secondary-storage instructions
- SDS reference number and COSHH (Control of Substances Hazardous to Health) classification applicable to the batch
Institutional COSHH assessments should be completed against the current SDS before the pen is used in any protocol. Peptide chemistry literature describes GHK-Cu (PubChem CID 23724905) as a copper-complexed tripeptide, but the stability of the 100 mg pen formulation depends on excipients, fill volume, and container closure, none of which can be inferred from chemical identity alone.

Research-Use-Only Limitations
In Great Britain, a product presented for treating or preventing disease in humans is a medicinal product and generally requires a marketing authorisation from the MHRA (Medicines and Healthcare products Regulatory Agency); GHK-Cu holds no such authorisation, and a “research use only” label does not create a lawful human-use pathway [2]. The GHK-Cu 100 mg pen is supplied for in-vitro laboratory research only and is not for human or veterinary use.
Researchers handling the GHK-Cu 100 mg Copper Peptide Research Pen should treat labelled click counts as a format descriptor for in-vitro dispensing, not as a dosing schedule. Institutions procuring the pen for controlled laboratory work should confirm batch identity against supplier documentation by matching a CoA to your pen before use.
Related Research and Comparison Pages
GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (PubChem CID 23724905). Published in-vitro literature addresses its coordination chemistry and extracellular-matrix signalling properties, not the fill accuracy or click format of any merchant’s pen. Researchers drawing on that literature should keep the distinction clear: primary papers support mechanistic hypotheses for controlled laboratory work, not product validation.
Before using the GHK-Cu 100 mg Copper Peptide Research Pen in any protocol, consult the storage and handling guidance for the cold-chain prerequisites that underpin responsible laboratory use.
Key Takeaways
