Description
GHK-Cu is the copper-complexed form of the tripeptide glycyl-L-histidyl-L-lysine, and it is one of the more frequently requested research peptides in Canada for in-vitro work on skin, connective tissue and cellular ageing models. This listing is the reagent itself: a lyophilized vial with a batch-matched certificate of analysis, sold for laboratory research use and nothing else.
Overview
Each vial contains GHK-Cu as a lyophilized (freeze-dried) powder, which is the format most reagents of this class are supplied in because the dry state is considerably more stable in transit and in storage than a solution. The researcher reconstitutes in a solvent appropriate to the protocol at the concentration the experiment calls for, rather than accepting a fixed dilution chosen by the supplier. Four options are offered: 50 mg or 100 mg as a single vial, and the same two sizes in boxes of ten for laboratories running repeat experiments or multi-arm studies. Every lot is analyzed by an independent laboratory, Janoshik, for purity by HPLC and identity by mass spectrometry, and the corresponding certificate of analysis is available for the specific batch shipped. Orders leave Canada with tracking, packed discreetly and handled cold.
What it is known for
GHK-Cu is known first as a copper-binding peptide — the histidine and lysine residues coordinate copper(II), which is what distinguishes it from the uncomplexed GHK tripeptide and what most in-vitro protocols are actually interested in. Buyers choose this listing for the documentation rather than the molecule alone: the analysis is done by a third-party lab, not in-house, and the certificate is matched to the batch in the box, so purity and identity can be recorded in the methods section instead of assumed. Domestic fulfillment matters here too — no customs hold on a temperature-sensitive reagent.
Key features
- Lyophilized powder format — The dry form survives shipping and cold storage far better than a pre-mixed solution, and it leaves the researcher free to set concentration and solvent to suit the assay.
- Independent HPLC purity analysis — Purity is measured by a lab with no stake in the result, so an unexpected assay outcome can be attributed to the experiment rather than to an unknown impurity profile.
- Mass spectrometry identity confirmation — Confirms the material is the compound ordered and not a mislabelled or substituted peptide — the single most important check before a reagent enters a protocol.
- Batch-matched certificate of analysis — The documentation corresponds to the specific lot received, which is what reviewers, supervisors and internal QA actually ask for when methods are scrutinized.
- Copper-complexed tripeptide — Supplied as the copper(II) complex rather than the free peptide, so protocols calling for GHK-Cu do not require a separate complexation step.
- Four pack sizes including boxes of ten — Small pilot work can start with one 50 mg vial; longer studies can secure ten vials from a consistent supply rather than re-qualifying a new lot mid-project.
- Cold storage and tracked Canadian dispatch — The reagent is held and sent under conditions appropriate to a lyophilized peptide, with no international border stage where a parcel can sit unrefrigerated.
Benefits
- Analytical documentation you can cite, rather than a supplier’s word on purity
- Control over reconstitution concentration and solvent choice
- Consistent material across a multi-vial order for longer or repeated experiments
- Domestic shipping with tracking, avoiding cross-border delays on a temperature-sensitive item
- A clear, unambiguous research-use designation that suits institutional purchasing

Important information
- Research use only. This product is not a drug, supplement, food or cosmetic, is not intended to diagnose, treat, cure or prevent any disease, and is not for human or veterinary use, ingestion or administration.
- Request or download the certificate of analysis for your batch and file it with your experimental records before use.
- Keep vials cold and sealed until reconstitution; lyophilized peptides are more stable dry than in solution.
- Choose a reconstitution solvent appropriate to your protocol, and prepare only the volume the work requires — reconstituted material has a shorter working life than the dry powder.
- Inspect the vial on arrival and confirm the label, lot number and size match your order and the accompanying documentation.
Common questions
What is the difference between GHK and GHK-Cu?
GHK is the tripeptide glycyl-L-histidyl-L-lysine on its own. GHK-Cu is that peptide complexed with copper(II), which the histidine and lysine residues coordinate. Protocols specifying GHK-Cu generally require the copper complex, which is what is supplied here.
How is purity verified?
By HPLC at an independent analytical laboratory, Janoshik, with identity separately confirmed by mass spectrometry. The results are issued as a certificate of analysis tied to the specific batch you receive, rather than a generic specification sheet.
Does it arrive ready to use?
No. It is supplied as a lyophilized powder and must be reconstituted in a solvent suitable for your research application, at the concentration your protocol specifies.
Which size should I order?
A single 50 mg vial suits pilot or single-run work. The 100 mg vial reduces the number of reconstitutions for larger experiments, and the boxes of ten are intended for laboratories that want a run of material for extended or repeated studies.
Where does it ship from and how long does it take?
Orders ship from within Canada with nationwide tracking and discreet packaging. Transit time depends on destination and the service selected at checkout.
Can this be used on people or animals?
No. It is sold strictly as a laboratory research reagent for in-vitro use. It is not a drug, supplement, food or cosmetic and is not intended for human or veterinary administration.
In summary
A characterized GHK-Cu reagent with third-party HPLC purity and mass spectrometry identity data, a certificate of analysis matched to your batch, and four pack sizes covering everything from a single pilot run to an extended study — held cold and shipped tracked within Canada.

Best product ive used ever! Skin is glowing after 4-5 weeks.. I threw out most of my other skin care products. I also use a GHK-cu face cream on top of this but I bought somewhere else. It’s cleared my face completely. This product does wonders for your skin!!
