Empty Nasal Spray Bottle: Product Versus Container

An empty bottle is an accessory. A product listing should say clearly whether it contains only the container or additional parts; a photograph of a spray format does not establish its contents.
What the bottle label can specify
Look for declared capacity, bottle material, cap or nozzle type and pack quantity. These are physical specifications. They do not verify sterility after opening or suitability for any particular substance.
Do not confuse a container with a medicine
A blank bottle cannot make a peptide safe, effective or appropriately formulated for nasal delivery. The MHRA explains that classification and claims matter, while Cancer Research UK cautions about marketed Melanotan sprays.
Compare current listings
The nasal-kit category is a separate listing type that may show bottles and other items. Check its current itemised contents rather than assuming an empty bottle includes a vial or a ready-made spray.
