GHRP-6 Spray supplies GHRP-6, also developed under the code SKF-110679, a synthetic hexapeptide with the sequence His-D-Trp-Ala-Trp-D-Phe-Lys-NH2 that acts as a reference ligand for GHS-R1a, the ghrelin receptor. Its free-peptide values are C46H56N12O6, 872.45 g/mol average mass, CAS 87616-84-0, with 145177-42-0 listed for an acetate salt form in supplier databases. CD36 has also been reported as a secondary binding target for this sequence. Offered in a 10 mg spray-dispensed size for laboratory research use only.

GHRP-6 Spray is Veracue’s spray-dispensed packaging of GHRP-6, a synthetic six-amino-acid peptide built with the sequence His-D-Trp-Ala-Trp-D-Phe-Lys-NH2. The underlying molecule is identical to the one documented on Veracue’s GHRP-6 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 GHRP-6 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.
GHRP-6 Spray and Veracue’s GHRP-6 vial listing describe one molecule: a C-terminally amidated hexapeptide with two D-amino acids, D-Trp and D-Phe, at positions 2 and 5. 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 hexapeptide 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.
GHRP-2 and GHRP-6 are the two most-referenced compounds in the growth hormone secretagogue literature. They are related, not interchangeable, and the comparison below is descriptive, not a ranking.
| Parameter | GHRP-6 | GHRP-2 |
|---|---|---|
| Sequence | His-D-Trp-Ala-Trp-D-Phe-Lys-NH2 | D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH2 |
| Molecular weight | 872.45 g/mol (free peptide) | About 818 g/mol (free peptide) |
| Generation | First-generation GHRP | Second-generation GHRP |
| Receptor | GHS-R1a; CD36 reported as a secondary target | GHS-R1a |
| Catalog formats Veracue offers | Vial and spray | Vial and spray |
This table compares molecular structure and receptor context only. Catalog format is listed separately because it is a packaging detail, not a property of the molecule itself, and it does not change which receptor a given peptide engages.
GHS-R1a is the ghrelin receptor, expressed on pituitary somatotroph cells and on a subset of hypothalamic arcuate-nucleus neurons. Receptor activation is reported to engage Gq and phospholipase-C signaling with downstream calcium mobilization, a route distinct from the cAMP-driven signaling used by GHRH-receptor agonists such as sermorelin or CJC-1295. GHRP-6, in either packaging format Veracue offers, is studied as an early reference ligand on the GHS-R1a side of this receptor pharmacology.
Because "Spray" and "vial" describe packaging rather than chemistry, a methods section should still name the molecule precisely by sequence 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, administration or usage guidance of any kind.
Identity and purity for GHRP-6 Spray are established the same way as for any GHRP-6 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 hexapeptide 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 GHRP-6 Spray 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 GHRP-6 | Sequence order; purity |
| Tandem MS | Sequence evidence | Quantity or purity |
| Amino acid or elemental 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 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.
GHRP-6 free peptide and GHRP-6 acetate share one sequence but not one formula weight; supplier chemical databases list CAS 87616-84-0 for the free peptide and CAS 145177-42-0 for the acetate salt. 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.
GHRP-6 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, and 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.
