AHK-Cu Spray

AHK-Cu Spray is supplied as a pre-dissolved, sterile-filtered solution in amber glass bottles fitted with a metered atomizer, at 50 mg or 100 mg per unit. The characteristic blue tint comes from the coordinated copper ion and is expected rather than a defect. Buffering is chosen specifically to hold the copper complex intact, since both acidic and strongly alkaline conditions strip the metal from the peptide backbone. Headspace is nitrogen-purged before capping, and no reconstitution step is required.

Store AHK-Cu 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. Watch the colour: a drift from blue toward green or a loss of tint altogether signals copper coordination loss, which is the failure mode specific to this compound class and one that no peptide purity check would catch. Avoid chelating agents entirely. Brief transit excursions to 15°C to 25°C (59°F to 77°F) are tolerated.

AHK-Cu is a three-residue peptide, alanyl-histidyl-lysine, coordinated to a copper ion, and the copper is the functional centre rather than an additive. The histidine imidazole nitrogen and the peptide backbone nitrogens hold the metal in a square-planar arrangement, and research treats the complex as a copper delivery vehicle. That matters because several extracellular matrix enzymes are copper-dependent, lysyl oxidase among them, and lysyl oxidase performs the cross-linking that gives collagen and elastin their tensile properties. The single-residue difference from GHK-Cu, alanine in place of glycine at the first position, is the whole structural distinction between the two. Pyo and colleagues reported effects on dermal papilla cells and vascular endothelial growth factor expression in cultured human hair follicles.

Yes. Qualified procurement partners can request alternative concentrations, non-standard bottle volumes, unlabeled or private-label presentation, or co-formulation with complementary copper peptide research compounds such as GHK-Cu. 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 copper coordination against demetallation. We ship nationwide across all 50 US states and internationally via express couriers with discrete, border-optimized clearance and full delivery assurance.
