Read product strength, cartridge quantity and pack contents
The same compound can be sold in different formats and pack sizes. Read the amount per container and the number of containers together.

Amount per vial or cartridge
A label such as “5 mg” on a vial is the total stated amount in that vial. For a dual-chamber listing, the strength button refers to one cartridge. It does not describe an amount per click, a schedule or a personal dose.
Multiply strength by pack count
For example, 250 mcg × 8 cartridges contains a stated total of 2 mg across the box. A four-cartridge option has a different pack total even if the cartridge strength is the same. This is pack arithmetic, not a recommendation for use.
Starter pack or refill only?
Supreme multi-dose pen listings separate “first purchase—pen + refill” from “refill only”. The starter option includes the matching pen; the refill option is for an existing compatible pen. The side-loading dual-chamber injector is a separate product and uses a different cartridge system.
Diluent and accessories
Supreme dual cartridges include liquid diluent in their second chamber. Dry-vial listings do not include diluent unless the selected pack explicitly says so. Check the listing for the exact device, accessory and container count instead of inferring contents from a photograph alone.
Before adding to cart
Confirm compound, format, strength, pack quantity, selected price and currency. Open “In the box” for the supplied contents. If you are unsure which option fits a device you already have, send the product name or device model to support before ordering.
