Administration protocol (research)
- 1. Follow the administration protocol defined in the study design.
- 2. Confirm dispense volume matches the calculated value above.
- 3. Record batch number, mass and timestamp in the lab notebook.
- 4. Dispose of needles in an approved sharps container.
Study cadence
- • Many protocols reference a 7-day interval.
- • Maintain a fixed interval across the study window for comparability.
- • Record the day and time of each measurement.
Reconstitution medium
- • Pre-filled pens require no reconstitution.
- • For lyophilised peptides, use bacteriostatic or sterile water per protocol.
Storage
- • Store refrigerated at 2–8°C, protected from light.
- • Do not freeze reconstituted solution.
- • Keep secured in the laboratory and out of reach of unauthorised persons.
