GLP-3RTA Spray delivers GLP-3RTA, research code LY3437943, a 39-amino-acid peptide backbone conjugated to a C20 fatty diacid at the lysine in position 17. This single engineered molecule is studied for activity across three receptor targets, GIPR, GLP-1R and GCGR, rather than acting as a blend of separate compounds. Its reference values are C221H342N46O68, about 4,731 g/mol average mass, CAS 2381089-83-2. Veracue offers this spray-dispensed peptide in 10 mg, 20 mg, 30 mg and 60 mg sizes, strictly for laboratory research use only.

GLP-3RTA Spray is Veracue’s spray-dispensed packaging of GLP-3RTA, a synthetic peptide engineered as a single molecule that carries a lipid attachment and is studied for activity across three receptor systems at once. The underlying molecule is identical to the one documented on Veracue’s GLP-3RTA 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.

Veracue lists GLP-3RTA 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.
GLP-3RTA Spray and Veracue’s GLP-3RTA vial listing describe one engineered molecule: a 39-amino-acid peptide backbone carrying a C20 fatty diacid through a linker at lysine 17, built so that a single structure can engage three receptor systems rather than relying on a blend of separate compounds. Packaging format has no bearing on formula or mass, so these values are identical across both listings.
No. The compound reported under this listing is the same lipid-conjugated peptide reported under the vial listing, research code LY3437943. 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.
GLP-3RTA Spray carries over a central identity point unchanged from the vial listing: it is one engineered molecule, not three compounds mixed together. In reported receptor assays it shows a distinct balance of activity across the GIP, GLP-1 and glucagon receptors. "Spray" describes how this listing is packaged and dispensed; it has no bearing on which receptors the molecule engages or how.
| Receptor | Full name | Research background |
|---|---|---|
| GIPR | Glucose-dependent insulinotropic polypeptide receptor | Linked to glucose-dependent insulin secretion |
| GLP-1R | Glucagon-like peptide-1 receptor | Linked to glucose-dependent insulin secretion |
| GCGR | Glucagon receptor | Mainly known for glucagon’s role in glucose and energy metabolism |
This table describes receptor biology only. It applies equally to the vial and spray-dispensed packaging of GLP-3RTA, since packaging format does not change which receptors a given molecule engages.
GIPR and GLP-1R are both linked to glucose-dependent insulin secretion, while GCGR is mainly known for glucagon’s role in glucose and energy metabolism. Researchers have proposed that engaging all three receptors from one molecule may produce signaling patterns that differ from single- or dual-receptor peptides. How the three signals interact remains an open research question, independent of which Veracue packaging format a lot was supplied in.
Because "Spray" and "vial" describe packaging rather than chemistry, a methods section should still name the molecule precisely by research code, formula or CAS number, 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 guidance of any kind.
Identity and purity for GLP-3RTA Spray are established the same way as for any GLP-3RTA lot. Because the molecule is a lipid-conjugated peptide rather than a simple chain, liquid chromatography paired with mass spectrometry is used to confirm that an intact mass matches the molecule’s theoretical value. Chromatography alone shows that most detected material elutes together; it does not by itself confirm identity, since a related lipidated 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 formula and mass references listed on the GLP-3RTA Spray at a Glance table above.
| Method | Tells a researcher | Does not prove by itself |
|---|---|---|
| LC-MS / ESI-MS | Intact mass consistent with GLP-3RTA | Chromatographic purity |
| RP-HPLC | Chromatographic purity (area %) | Identity |
| Tandem MS | Sequence or fragment evidence | Quantity or purity |
| Charge-state deconvolution | Neutral mass derived from multiply charged ions | Identity on its own |
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, chromatography result, 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 molecule, and is the purity figure paired with a mass result from the same lot. Packaging format does not change what counts as adequate documentation.
GLP-3RTA’s C20 fatty diacid is part of its identity, not an incidental feature. An identity result should show a mass consistent with the intact conjugate rather than the bare peptide backbone alone. Confirm this on the lot’s certificate 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.
GLP-3RTA 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.
