KLOW Spray is Veracue’s spray-dispensed form of KLOW, a blend name used in the research-peptide market rather than a defined single molecule. Listings using this name most often name four components: KPV (Lys-Pro-Val), GHK-Cu (copper-bound Gly-His-Lys), BPC-157 (the 15-residue GEPPPGKPADDAGLV) and TB-500 (the fragment Ac-LKKTETQ). Because KLOW is a mixture, no single sequence, formula or molecular weight applies to it as a whole; each named component carries its own identity and CAS number. Supplied as an 80 mg spray-dispensed size for laboratory research use only.

KLOW Spray is Veracue’s spray-dispensed packaging of KLOW, a blend name used in the research-peptide market rather than a single peptide molecule. The underlying blend is identical to the one documented on Veracue’s KLOW vial listing; only the packaging and dispensing format differ between the two listings.
A single peptide name points to one sequence, one formula and one molecular weight. KLOW points to a mixture, so none of those apply to the blend as a whole, regardless of which packaging format it is supplied in. Combining the components does not create a new molecule.
"Spray" is a packaging and dispensing descriptor, nothing more. It does not establish a route, a concentration, or a formulation, and none of those specifics should be inferred from the product name. Component ratio, chemical form, fill volume and storage conditions are reported on each lot’s own documentation and can be requested through the contact page.

KLOW Spray and Veracue’s KLOW vial listing describe one blend. The four components below are the ones most often named in listings that use the KLOW name, and packaging format has no bearing on which components are named or how each is identified.
KPV is a tripeptide made of lysine, proline and valine. Its sequence corresponds to the C-terminal region of alpha-melanocyte-stimulating hormone.
GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine. It is a peptide-copper complex, not an unmodified peptide, so both the peptide identity and the copper content need to be specified.
BPC-157 is a synthetic pentadecapeptide, meaning a chain of fifteen amino acids. Its sequence corresponds to a partial sequence of a larger protein found in gastric juice.
TB-500 is a market term whose meaning can vary between suppliers. It can refer to a short synthetic fragment of thymosin beta-4 or, in some listings, to the full-length protein. The exact species should be taken from the product documentation or lot-specific analytical record rather than assumed from the label.
| Component | Molecular class | Identity note |
|---|---|---|
| KPV | Tripeptide (Lys-Pro-Val) | Corresponds to the C-terminal region of alpha-melanocyte-stimulating hormone |
| GHK-Cu | Peptide-copper complex | Copper(II) complex of Gly-His-Lys; copper content is its own measurement |
| BPC-157 | Pentadecapeptide | Synthetic; partial sequence of a larger protein found in gastric juice |
| TB-500 | Thymosin beta-4 fragment or full-length protein | Species varies between suppliers and should be confirmed from lot documentation |
Veracue lists KLOW in more than one packaging format because research groups source and track material differently depending on how it is packaged. Keeping the formats as separate listings keeps lot records, images and documentation specific to the packaging a researcher actually ordered, rather than mixing records across formats.
No. The blend reported under this listing is the same KLOW composition reported under the vial listing. What differs between the two listings is how the material is packaged and dispensed, not which components are named or how each is identified.
No. Each component has its own separate literature, tied to its own models and materials. A finding for one peptide answers a question about that peptide, not about a four-component mixture, and no direct study of the KLOW combination was identified. Nothing here describes a combined effect, in either packaging format.
Not necessarily. KLOW and Glow are market blend names whose compositions can vary by supplier. Market usage often distinguishes KLOW by the addition of KPV, but that is not a universal formulation, so compare documentation rather than names.
Because "Spray" and "vial" describe packaging rather than composition, a methods section should still name each component precisely by sequence or CAS number where applicable, and separately note the catalog format and lot number actually used. This page provides molecular reference information and general research context only, and Veracue provides no dosing, administration or usage guidance of any kind.
A blend certificate has to answer more questions than a single-peptide one, because one headline number cannot describe several molecules. It should name the lot, identify every component and make clear which component each result refers to. Packaging format has no bearing on which analytical methods apply; a spray-dispensed lot and a vial lot of the same blend are verified against the same component identities listed in the table above.
| COA element | What it tells you | What it does not establish |
|---|---|---|
| Lot or batch number | Links the report to one production lot | Anything at all unless it matches the unit label |
| Component identities | Which molecules the report says are present | That each is present at the stated amount |
| Component-level results | How each individual component performed under test | Blend-level behavior in solution |
| HPLC purity | Share of detected signal in the stated peak or peaks | Identity or component amounts |
| Mass spectrometry and identity data | Whether observed masses match the expected species | Purity, or how much material is present |
| Purity scope (blend or component) | Whether the number covers the mixture or one ingredient | Component-level certainty, if the figure is blend-level |
| Testing laboratory and date | Who tested the lot and when | Independence, unless the relationship is disclosed |
A generic certificate for one component does not prove the identity, composition or purity of the finished blend. Certificates vary between laboratories, so treat this as what a COA may include, and see the certificate page for how lot documentation is published.
A certificate of analysis describes one lot, never a packaging format or a blend in general. Before relying on any figure, confirm that the lot number on the certificate matches the container and the order record for the spray-format unit received.
For the copper complex, copper content should be confirmed as its own measurement rather than assumed from the peptide result alone, regardless of which packaging format the lot was supplied in.
No. The verification question is the same: does this lot identify every component, and is each component’s identity result paired with the method used to produce it. Packaging format does not change what counts as adequate documentation.
The report should say which. A single blended percentage can hide a shortfall in one component, so a value for each is more informative, in either packaging format.
For each lot, keep the catalog listing snapshot, the lot-specific certificate, the stated component list, the receipt date, labeled storage conditions, and the packaging format actually received. Recording format alongside the usual identity fields keeps multi-format catalogs like this one traceable lot to lot.

It has not been evaluated by the FDA. This page contains no dosing, administration or usage guidance of any kind, and the word "Spray" in the product name describes Veracue’s packaging and dispensing format only.
