Epithalon Spray supplies the four-amino-acid peptide Ala-Glu-Asp-Gly (AEDG), also written Epitalon or Epithalone, developed as a sequence-defined synthetic counterpart to epithalamin, an earlier pineal-tissue preparation. Reference-database values put its formula at C14H22N4O9 and average mass near 390.35 g/mol, PubChem CID 219042; CAS registration for this sequence varies across public sources, so confirm it on a lot’s own paperwork. Veracue offers this spray-dispensed peptide in 10 mg and 50 mg sizes, for laboratory research use only.

Epithalon Spray is Veracue’s spray-dispensed packaging of Epithalon, a synthetic tetrapeptide built from four amino acids with the sequence Ala-Glu-Asp-Gly (AEDG). The underlying molecule is identical to the one documented on Veracue’s Epithalon vial listing; only the packaging and dispensing format differ between the two listings.
"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. Chemical form, concentration, fill volume and storage conditions are reported on each lot’s own documentation and can be requested through the contact page.

Formula, mass and PubChem figures above are reference-database values for the AEDG sequence and are not a Veracue lot result. CAS registration for this sequence varies across public databases, so a lot-specific CAS value should be confirmed on that lot’s own documentation rather than assumed from this page.
Veracue lists Epithalon 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.
Epithalon Spray and Veracue’s Epithalon vial listing describe one molecule: a linear four-residue chain of alanine, glutamic acid, aspartic acid and glycine, developed as a sequence-defined counterpart to epithalamin, an earlier pineal-tissue preparation. Packaging format has no bearing on sequence, formula or mass, so these values are identical across both listings.
No. The compound reported under this listing is the same AEDG tetrapeptide reported under the vial listing. What differs between the two listings is how the material is packaged and dispensed, not its chemical identity.
In Veracue’s catalog, "Spray" is a packaging and dispensing term, comparable to "vial" or "powder" on other listings. It tells a researcher how the product is dispensed from its container. It does not specify a concentration, a carrier, a route, or a formulation, and it is not shorthand for any particular method of use. Those details, where applicable, live in lot-specific documentation rather than in the catalog name.
Treating a packaging word as a technical specification is a common source of error when comparing listings across suppliers. A researcher documenting materials in a methods section should cite the lot’s own documentation for format-specific details rather than inferring them from the word "Spray" alone.

This table compares research lineage and structure only. Catalog format is listed separately because it is a packaging detail, not a property of the molecule itself, and shared research lineage does not mean shared findings across these materials.
Published work on the AEDG sequence spans cell-culture studies, including telomerase- and telomere-related endpoints, animal studies, and older research-tradition publications associated with pineal-gland and circadian biology. Each finding is specific to the model and conditions used in that study, and none of it should be read as an established mechanism or outcome for this or any packaging format.
Because "Spray" and "vial" describe packaging rather than chemistry, a methods section should still name the molecule precisely by sequence, 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.
Identity and purity for Epithalon Spray are established the same way as for any Epithalon lot: reverse-phase HPLC for chromatographic purity, and mass spectrometry (typically ESI-MS or MALDI-TOF) to confirm that the observed mass matches the molecule’s theoretical value. HPLC alone shows that most detected material elutes together; it does not by itself confirm identity, since a closely related short peptide can produce an equally clean trace.
Packaging format has no bearing on which analytical methods apply. A spray-dispensed lot and a vial lot of the same molecule are verified against the same sequence, formula and mass references, listed on the Epithalon at a Glance table above.
| Method | Tells a researcher | Does not prove by itself |
|---|---|---|
| RP-HPLC | Chromatographic purity (area %) | Identity |
| ESI-MS / MALDI-TOF | Mass consistent with Epithalon | Sequence order; purity |
| Tandem MS | Sequence evidence | Quantity or purity |
| Amino acid analysis | Net peptide content | Identity of impurities |
A certificate of analysis describes one lot, never a packaging format or a compound 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.
A complete certificate separates product identity, lot number, chemical form, HPLC result with chromatogram, mass spectrometry result with observed and theoretical mass, test date and testing laboratory. Where concentration or fill-volume figures are relevant to a spray-format unit, they are reported on that lot’s own documentation rather than inferred from the catalog listing. The certificate page explains how to request lot documentation for either format.
No. The verification question is the same: does this lot match the stated sequence, and is the purity figure paired with a mass result from the same lot. Packaging format does not change what counts as adequate documentation.
Short peptides such as Epithalon can be supplied as the free peptide or as a salt form, and different forms do not share one formula weight. If a lot’s documentation leaves the form unstated, any mass-based calculation can carry a silent error. Confirm the form on the lot’s certificate and use the matching formula weight, regardless of packaging format.
For each lot, keep the catalog listing snapshot, the lot-specific certificate, the stated chemical form, 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.
Epithalon Spray is supplied for laboratory research and analytical characterization only. It is not intended for human or veterinary use, or for ingestion, injection or any form of administration. 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.
