Vial, dual chamber, pen or nasal spray: what changes?
Start with what is supplied, which device it fits and what is included. A presentation changes the packaging and preparation—not the evidence for a compound.

Powder vials
A lyophilized vial contains dry material. The milligram amount is the total in that vial. Diluent and accessories are separate unless the selected listing explicitly includes them. Check the pack contents before comparing prices.
Dual-chamber cartridges
Supreme dual cartridges keep lyophilized powder and supplied liquid diluent in separate chambers until activation. Strength means the amount in one cartridge; the box option also states how many cartridges it contains. The compatible side-loading dual-chamber injector is sold separately.
Ready-mixed pens and refills
Supreme multi-dose and Calyssee pens contain ready-mixed liquid. Supreme offers a first-purchase option with a reusable pen and matching single-chamber refill, and a refill-only option. The total on the label is not the amount per click. A single-chamber pen refill and a dual-chamber cartridge are different systems. Check compatibility before ordering.
Nasal sprays
These listings use nasal-spray packaging. Read the label for total content and concentration. A format description does not establish absorption, effectiveness or equivalence to another presentation.
Compare the complete pack
Compare the same compound, total amount, number of containers and included device. A refill-only price cannot be compared directly with a pen starter pack. Your selected option and currency determine the displayed price. Open the product details to check contents, storage and batch documentation.
