PT-141 nasal or pen: understand the difference
What the name, total label amount and presentation describe.

Read the full label
The BRL references shown here are PT-141 10 mg in a nasal presentation and in a pen. The figure describes the stated amount in the full product, not a personal dose or a spray count.
One format at a time
The selector deliberately displays one product at a time. A pen and nasal presentation are not presented as a bundle or a recommendation to combine them.
Keep your enquiry specific
Ask for full ingredient identity, liquid volume where applicable, formulation, batch identification and storage directions. These specifications are separate from whether a product is appropriate for a particular person.
