Purity vs quantity distinction
Purity (%) and reported quantity are distinct analytical parameters. Review purity and reported quantity separately, and confirm the labeling and assay basis for the batch proposed for your order.

DocumentationBatch COA stating RP-HPLC purity and MS identity, plus SDS/MSDS and specification sheet. Karl Fischer water content and counter-ion data are arranged per project where a specification requires them.
Quotation ScopeFill amount, vial count, packaging format, MOQ, and lead time are confirmed together at quotation stage.
PackagingSealed lyophilized vial with stopper and cap. Neutral-label or private-label discussion for qualified projects. Store unopened vials at 2–8 °C as standard, or −20 °C for long-term storage — approximately 24 and 36 months respectively as WUMO product guidance, with the batch COA and product documentation governing. Keep sealed, protected from light and moisture.
ComplianceBuyer-side market review required
Why buyers trust WUMO
Real content, documented — not guesswork
In peptide sourcing, chromatographic purity and delivered quantity require separate evaluation. We keep purity and labeling basis distinct on available documentation, so buyers can review analytical parameters for their quoted batch before ordering.
Batch-specific documents
Batch documentation reflects the specific lot produced. Ask which batch-specific documents are available for the quoted lot, including COA and supporting HPLC or MS records where applicable.
Documented before commitment
Ingredient identity (INCI / CAS), specification sheet, and SDS are available for technical review. Confirm documentation for the batch proposed for your order before purchase.
Sample Verification Record
Third-Party Sample Report
Results below relate to the submitted sample identified in the laboratory report. They do not establish uniformity across the entire lot or confirm that a quoted or delivered batch is the same batch. Request documentation for the batch proposed for your order.

Overview
Overview
Batches are supported by analytical verification — purity assessed by RP-HPLC against a ≥98.0% specification (99.969% on the current batch) and identity confirmed by ESI-TOF mass spectrometry — with batch-specific COA, HPLC, and MS reports provided to qualified buyers on request.
WUMO supplies GHK-Cu as a 50mg lyophilized vial fill specification intended for B2B sourcing conversations with formulation development teams working on cosmetic formulation and topical formulation projects. The 50mg fill is a project-level specification; buyers should review the documentation set against their own formulation, packaging, and local regulatory requirements.

FAQ
What does the 50mg fill specification refer to?
The 50mg figure is a vial fill quantity, supplied as a B2B project specification. It is not a use amount or formulation guidance.
What documentation can be shared under B2B technical evaluation?
WUMO can share batch-specific COA, copper content records, identity and purity records, and water content records, with scope subject to project confirmation.
Does WUMO supply cosmetic-grade and research-grade GHK-Cu separately?
Grade availability is subject to project confirmation. Formulation development teams should specify the documentation set required at inquiry stage.
Can the outer packaging be customized for a formulation project?
Custom outer packaging and labeling are discussed on a project basis, not pre-published. Buyers should raise packaging requirements during the inquiry.
Is copper content separately documented?
Copper content documentation is part of the documentation review scope for this product. Specific values are batch-specific and not stated on this page.
Does this page describe what GHK-Cu does in a formulation?
No. This page is limited to vial fill specification, documentation scope, and B2B sourcing review.
Specification and documentation references
Before requesting a quotation, these guides cover the specification and document questions that come up most often on this product.
- GHK-Cu supplier qualification guide — identity, HPLC, copper content and batch documents.
- Copper content vs purity percentage — why the two figures answer different questions.
- What a 10mg vial actually contains — how peptide content, counterion, moisture and excipients divide up the mass, and what a per-vial claim needs behind it.
- Lyophilized cake appearance and reconstitution — why cakes hold or collapse, what the excipient system does, and what can reasonably be specified.
FAQ
Frequently Asked Questions
What is the copper content of GHK-Cu, and is it the same as purity?
They are different measurements. HPLC purity shows how much of the chromatographic profile is the target compound, while copper content confirms the elemental copper by weight. For Copper Tripeptide-1 the theoretical copper content is about 15.8% by weight, verified by ICP-MS or AAS. Confirm both purity and copper content on the current batch COA rather than relying on a product page or old specification sheet.
What documentation comes with the GHK-Cu 50mg vial?
Each GHK-Cu 50mg vial is supported by an HPLC purity COA (greater than 99%), mass-spectrometry identity confirmation, and SDS/MSDS and specification documents on request, with batch number and per-batch traceability. Request the COA for the specific lot you will receive before issuing an RFQ.
What is the CAS number and molecular formula for GHK-Cu?
GHK-Cu, the copper complex, is CAS 89030-95-5, molecular formula C14H22CuN6O4, molecular weight about 401.9 g/mol. The free tripeptide GHK without copper is a separate entry (CAS 49557-75-7). Confirm which one a quotation refers to, since the two are sometimes listed interchangeably.
How should GHK-Cu vials be stored and shipped?
Store lyophilized vials cold — 2 to 8 degrees Celsius for routine handling, or minus 20 degrees Celsius for longer-term storage. Sealed, dry lyophilized powder is stable across multi-week international shipping windows; the practical priorities are protection from moisture and from prolonged heat rather than same-day cold chain. Confirm storage guidance on the batch COA.
What GHK-Cu purity should I expect, and what is a red flag?
Our GHK-Cu is supplied at greater than 99% HPLC purity, confirmed per batch by COA. In the research market, purity below about 90%, a single vendor COA reused across many vials instead of a per-batch COA, or a year-old COA that cannot confirm current purity are common red flags worth checking before bulk purchase.
Is this GHK-Cu supplied for research use?
Yes. The GHK-Cu 50mg vial is supplied as a research-use raw material and lyophilized vial for laboratory and B2B sourcing evaluation. Documentation and sample support are provided for qualified buyers reviewing the material for their own projects.
OEM / Private Label
Want GHK-Cu 50mg Vial under your own brand?
For finished lyophilized peptide vials with custom labels and packaging -- covering MOQ, sample or pilot evaluation, and batch documentation such as COA, sterility, and endotoxin reports -- see our private label peptide vial (OEM / ODM) service.
