Tesamorelin Spray

Tesamorelin Spray is supplied as a pre-dissolved, sterile-filtered solution in amber glass bottles fitted with a metered atomizer, at 10 mg or 20 mg per unit. At 44 residues it is one of the longer peptides in our catalog, and the pre-dissolved format removes the slow, incomplete redissolution that long chains show when supplied as a powder. Headspace is nitrogen-purged before capping to protect the methionine residue, and no reconstitution step is required.

Store Tesamorelin 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. Do not freeze: long peptide chains like this one nucleate aggregates at the ice interface, and the methionine residue oxidizes faster once the structure is disturbed. Brief transit excursions to 15°C to 25°C (59°F to 77°F) are tolerated.

Tesamorelin is a stabilized 44-amino-acid analog of growth hormone-releasing hormone that binds the GHRH receptor on pituitary somatotroph cells. Receptor activation couples to adenylyl cyclase, raising cAMP and activating protein kinase A, which phosphorylates the CREB transcription factor and drives Pit-1-dependent transcription of the growth hormone gene. The result in laboratory models is increased growth hormone synthesis and release, with hepatic IGF-1 as the downstream readout. What distinguishes Tesamorelin is where it acts. Ghrelin-receptor secretagogues such as Ipamorelin and GHRP-6 work through an entirely separate receptor, while Tesamorelin acts upstream at the GHRH receptor and preserves the native pulsatile release pattern.

Yes. Qualified procurement partners can request alternative concentrations, non-standard bottle volumes, unlabeled or private-label presentation, or co-formulation with complementary growth factor research compounds such as Ipamorelin. 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 oxidation-prone methionine residue and guard this long peptide chain against aggregation. We ship nationwide across all 50 US states and internationally via express couriers with discrete, border-optimized clearance and full delivery assurance.
