Handling it properly

Reconstitution, and the mistakes that ruin a vial

Bacteriostatic water, why you run it down the glass, and what shaking does to a peptide.

The math, once, so it never confuses you again

Milligrams, millilitres and insulin-syringe units. Worked examples for the common vial sizes.

Storage and stability after mixing

What 28 days means, which compounds are fussier than others, and the signs a reconstituted vial has gone off.

How these are administered in practice

Subcutaneous injection as it is commonly done, sites, rotation, sterile technique, sharps disposal. Reported practice, not instruction.

Keeping records

A log that lets you tell what changed. The template members use.
