GHK-Cu analytical verification and batch documentation
What the purity figure on this page is, who measured what, and which of the two a reader is looking at.
Specification. Every batch is released to >99% purity by HPLC. That is a threshold Volta sets, and it is a promise rather than a measurement.
Measurement. CoreMass Laboratories reported 99.40% by HPLC-UV, LC-MS for lot VPGC50101 on November 13, 2026, and confirmed identity at an observed mass of 59.54 mg net peptide. That report covers this vial.
The certificate can be checked against the laboratory rather than against us: verify on CoreMass Laboratories.
Checking a certificate. The batch number printed beside the price is derived from the compound code and the vial strength; the lot number on a certificate is transcribed from the document. They are produced independently, so comparing them is a real check. How to read one is set out in the quality and testing methodology page.
For in-vitro laboratory research by qualified professionals only. Not for human or animal administration. Not a drug, food, cosmetic or dietary supplement. Not intended to diagnose, treat, cure, mitigate or prevent any disease.
GHK coordinates Cu(II) through the glycine amino nitrogen, the deprotonated nitrogen of the Gly-His amide bond and the histidine imidazole, which delivers the metal in a redox-buffered form rather than as free copper ion. In fibroblast and other cell cultures it is studied for effects on the expression of extracellular matrix genes. Its small size makes identity by mass spectrometry straightforward, and the copper content is part of what distinguishes the complex from the free tripeptide on a certificate. This vial holds 50 mg of lyophilized powder and is released to a >99% purity specification by HPLC.

The figure an identity check has to land on
Detection
214 nm
Identity by mass: the ions to expect
An electrospray source protonates the molecule rather than weighing it neutral, so a spectrum shows a series of charge states rather than the molecular weight itself. These are the m/z values 401.91 g/mol produces, and they are what a mass spectrum on a certificate for GHK-Cu has to match.
| Ion | Charge | Expected m/z |
|---|---|---|
| [M+H]+ | 1+ | 402.92 |
Why 214 nm
The sequence carries neither tryptophan nor tyrosine, so it has no absorbance at 280 nm. Detection is at 214 nm, on the peptide bond itself.
This matters when reading someone else's certificate: a purity figure quoted at 280 nm for a compound with no aromatic residue is measuring an absorbance the molecule does not have.
What a certificate for GHK-Cu should carry
A purity percentage on its own is not checkable. These are the entries that make one verifiable, and their absence is the most common weakness in a research-peptide certificate.
The chromatogram, not only the number
A stated area percent with no trace behind it cannot be read for the shape of the main peak or for what eluted beside it. The HPLC interpreter walks through what a trace shows.
Net peptide content, separately from gross mass
A lyophilised peptide is a salt, usually of trifluoroacetic or acetic acid, plus residual water. The vial's stated milligrams are gross; net peptide content is the fraction of that mass which is the molecule. The two differ by ten to twenty percent routinely, and only one of them is what the price is per milligram of. The net peptide content calculator converts between them.
The counterion, named
Which salt form the powder is in changes the net content and the pH the powder dissolves at. A certificate that never names it leaves both unknowable.
Water content, by a stated method
Loss on drying and Karl Fischer water determination give different numbers, and a water figure with no method attached cannot be compared with anyone else's.
A laboratory and a report identifier
Without both, nothing on the document can be traced back to the laboratory that issued it. The red flag checker lists the rest.

GHK-Cu storage and stability
Handling as the product record states it, followed by the degradation chemistry this particular sequence is and is not exposed to.
Handling
Store lyophilized peptide at -20°C protected from light and moisture. Reconstitute in sterile water. Once reconstituted, store at 2-8°C and use within 30 days. Lyophilized powder is stable at room temperature for shipping and short-term storage.
What holds up
The degradation routes this compound is not exposed to, which is as specific a fact as the ones it is.
No oxidation-labile side chain
no Met, Cys or Trp in the sequenceThe three residues that oxidise readily are all absent, so the most common degradation route for a research peptide does not apply to this one. Air in the vial headspace is not the risk here that it is for a methionine-containing compound.
No deamidation site
no Asn or Gln in the sequenceDeamidation is the slow clock on most reconstituted peptides, and it needs an asparagine or a glutamine to run. This sequence has neither, so time in solution does not convert it to a one-dalton-heavier, more acidic relative.
No ultraviolet chromophore
no Trp or Tyr in the sequencePhoto-oxidation of peptides runs mainly through the aromatic side chains, and this sequence has none. Storing in the dark remains good practice for the excipients and the diluent, but the molecule itself has no strong absorber for ultraviolet light to act on.
Net hydrophilic
GRAVY -2.50A negative grand average of hydropathy means the side chains are on balance polar, which is the profile that stays in solution rather than associating. Freeze-thaw cycles are still worth avoiding, but this compound is not one of the hydrophobic sequences that aggregate irreversibly at an ice front.
Solubility window
calculated pI 10.1, net charge 1.1 at pH 7A peptide is least soluble within about a pH unit of its isoelectric point, where it carries no net charge. This one is far enough from neutral that it holds a real charge in an ordinary diluent, which is what keeps it dissolved.
Derived from the primary sequence GHK, calculated isoelectric point 10.11, GRAVY -2.5. Check the arithmetic with the peptide property calculator and the freeze-thaw estimator.

A bar set for this market, not converted from the US one
Whenever our British Columbia warehouse holds it, GHK-Cu 50mg ships from there to Canadian addresses, so the parcel never crosses a border; if it is only in our US warehouse in California, it crosses one. Shipping from British Columbia removes the failure a Canadian buyer of research peptides is usually weighing: an inbound international shipment can be held for import clearance or seized, and a domestic one has no clearance step to be held at.
Shipping is quoted live against the delivery address at checkout rather than estimated here, and both the standard and express tiers show their price and transit window before a payment method is chosen. The figure the page shows is the figure the rail charges: all three settlement rails price shipping through the same functions the quote does.
The Canadian figure above is not a loose conversion. Each product's US dollar base is chosen so that the live conversion lands on the Canadian shelf price set for this market, and the result is pushed up to a whole dollar rather than left carrying cents, so one figure serves the page, the feed and every payment rail. See the shipping policy for carriers and cut-off times, and the legal position on research peptides in Canada for the regulatory picture.

Laboratory notes, as transcribed
Identity confirmed as GHK-Cu by LC-MS. Chromatographic purity is the main-peak share of total integrated peak area by reversed-phase HPLC with UV detection. Two vials were measured: purity 99.40% and 99.42%, net peptide content 59.54 mg and 57.61 mg against a 50 mg label claim, a fill accuracy of up to 119.1%. Results relate only to the sample as received.
GHK-Cu 50mg volume pricing
Unit price at each quantity band, computed from the same tiers the cart applies. Nothing here is a promotional figure: these are the prices checkout charges.
| Quantity | Discount | Each, USD | You save each | Goods total, USD | Goods total, CAD |
|---|---|---|---|---|---|
| 1 unit | None | $39.00 | None | $39.00 | CA$56 |

The discount is applied to the quantity of this one product, not to the number of different items in the cart. It is the better of the volume tier or any add-on offer, never both.
CAD is the goods total for an order of this product alone, before shipping and tax. A cart holding other products converts its goods total once, so the figure there will differ by a dollar or so.
