GHRP-2 Spray

GHRP-2 Spray is supplied as a pre-dissolved, sterile-filtered solution in amber glass bottles fitted with a metered atomizer, at 100 mg per unit. The higher unit strength relative to GHRP-6 reflects how it is typically used in reference and method-development work rather than any difference in potency. The naphthylalanine residue makes the peptide more hydrophobic than its hexapeptide predecessor, so the buffer accounts for that. Headspace is nitrogen-purged before capping, and no reconstitution is required.

Store GHRP-2 Spray refrigerated at 2°C to 8°C (36°F to 46°F), upright and protected from light, where sealed units remain within specification for up to 24 months. Once the atomizer is first actuated, use the unit within 30 days. This sequence is somewhat more robust than GHRP-6 because it carries one tryptophan rather than two and three D-configured residues rather than two, which together reduce both oxidation exposure and peptidase susceptibility. Avoid freeze-thaw cycling nonetheless. Brief transit excursions to 15°C to 25°C (59°F to 77°F) are tolerated.

GHRP-2, also catalogued as pralmorelin, is a six-residue agonist at the ghrelin receptor and a deliberate structural revision of the earlier hexapeptide GHRP-6. Receptor activation couples through Gq to phospholipase C, generating inositol trisphosphate that releases intracellular calcium and triggers growth hormone vesicle release from pituitary somatotroph cells. The design changes are specific: a naphthylalanine replaces one tryptophan and a third D-configured residue is introduced, modifications that increase potency and reduce the appetite stimulation characteristic of GHRP-6 while retaining the same receptor target. It occupies a middle position in this class, more potent than the original hexapeptide but without the clean hormone selectivity Raun and colleagues reported for Ipamorelin.

Yes. Qualified procurement partners can request alternative concentrations, non-standard bottle volumes, unlabeled or private-label presentation, or co-formulation with complementary secretagogue research compounds such as GHRP-6. Contact our corporate sales desk with your target concentration and unit count to scope the run.

Units ship in light-blocking, vacuum-sealed secondary packaging with temperature-stability buffers that hold the shipment inside the refrigerated range through transit. Amber primary containers and nitrogen-purged headspace protect the single tryptophan and the three D-configured positions. We ship nationwide across all 50 US states and internationally via express couriers with discrete, border-optimized clearance and full delivery assurance.
