HCG Spray

HCG Spray is supplied as a pre-dissolved, sterile-filtered solution in amber glass bottles fitted with a metered atomizer, at 5,000 or 10,000 international units per unit. Note the unit of measure: this product is specified by bioactivity rather than by mass, because glycoprotein preparations of identical weight can differ in activity depending on their carbohydrate composition. The buffered format also protects the heterodimer, which dissociates into inactive subunits under conditions a small peptide would tolerate. Headspace is nitrogen-purged before capping.

Store HCG 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. Never freeze and avoid vigorous agitation. The two subunits are held together by non-covalent interactions rather than a peptide bond, so freezing or shear stress can separate them into individually inactive halves while every conventional analysis still reports the correct components present. Brief transit excursions to 15°C to 25°C (59°F to 77°F) are tolerated.

Chorionic gonadotropin is not a peptide at all but a heterodimeric glycoprotein, and that architecture defines its behaviour. It consists of an alpha subunit shared with luteinizing hormone, follicle-stimulating hormone and thyrotropin, paired non-covalently with a beta subunit that supplies target specificity. The assembled dimer binds the luteinizing hormone and choriogonadotropin receptor, which couples through Gs to adenylyl cyclase, raising cAMP and activating protein kinase A. That cascade upregulates the steroidogenic acute regulatory protein, moving cholesterol into mitochondria and driving steroid hormone synthesis. Research shows an extended carboxy-terminal segment on the beta subunit carries additional carbohydrate chains, and it is this extension that gives chorionic gonadotropin a markedly longer circulating life than luteinizing hormone at the same receptor.

Yes. Qualified procurement partners can request alternative concentrations, non-standard bottle volumes, unlabeled or private-label presentation, or co-formulation with complementary neuroendocrine research compounds such as Kisspeptin. 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 glycosylation pattern that determines measured bioactivity. We ship nationwide across all 50 US states and internationally via express couriers with discrete, border-optimized clearance and full delivery assurance.
