Hands-on · step by step · no doses

Tutorials.

Four step-by-step walkthroughs for the physical side of the vial math: mixing a vial, reading a syringe, running a pen and priming a nasal pump. They cover handling and measurement, and they stop before administration.

The calculators do the arithmetic and the guides explain the science. These tutorials sit between the two: what to do with your hands, in what order, and why each step is there. Every one is sourced to public labels and safety guidance, and none of them suggests an amount.

The calculators these tutorials use.

The tutorials hand the arithmetic to these tools rather than repeating it. Each one converts numbers you enter and never pre-fills or suggests an amount.

What these tutorials will not tell you

No amounts, no frequencies, and no injection technique. Each tutorial ends where administration begins, because how and where to inject depends on the product and the person, and that belongs to a prescriber, a pharmacist, or the product's Instructions for Use.

The PepCue app draws the same line, so the site and the app give the same answer. If a product came with Instructions for Use, those win over anything here.
