FOR LABORATORY RESEARCH USE ONLY – NOT FOR HUMAN CONSUMPTION
1. What Is a Multi-Dose Research Pen?
A multi-dose research pen is a pre-filled, calibrated device designed to deliver precise,
repeatable volumes of Tirzepatide or Retatrutide solution during experimental protocols.
Each pen contains multiple research doses and is intended for use over several sessions
within a controlled laboratory environment.
- Pre-filled with a defined total volume
- Dial-based unit selection for consistent volume delivery
- Reduces handling error compared to manual vial preparation
- Supports structured, repeatable research designs
2. Before First Use (Initial Setup)
2.1 Inspect packaging
Confirm that the outer packaging is intact, the label is legible and there is no visible
damage or leakage. Do not use a pen that appears compromised.
2.2 Bring pen to room temperature
If stored in a refrigerator, allow the pen to rest at room temperature for
approximately 15–30 minutes before use. This helps maintain consistent pressure
and smoother unit delivery.
2.3 Attach a new sterile needle tip
Attach a compatible sterile needle tip firmly to the pen. Needle tips are
single-use only and must not be shared between experiments or operators.
2.4 Prime the pen (first use only)
To remove air from the system:
- Set the dial to the smallest available unit setting
- Hold the pen upright with the needle pointing upwards
- Press the plunger until a small droplet is visible at the tip
Priming typically only needs to be carried out once, before the first research use.
3. Unit Selection (General Principle)
Research pens are calibrated in units (volume), not milligrams (mass).
The relationship between units and mg depends on:
- Total mg of Tirzepatide or Retatrutide in the pen
- Total liquid volume inside the pen (ml)
For detailed examples and conversion logic, refer to the
Dosage Guide page.
4. During Use
When using a research pen during experimental protocols:
- Always use a fresh sterile needle tip for each experimental sequence
- Dial carefully to the required unit volume, avoiding over-rotation
- Do not force the dial or plunger if resistance feels abnormal
- Use consistent timing and unit volumes for repeatability between sessions
5. After Each Use
- Remove the needle tip and dispose of it safely in an appropriate sharps container
- Replace the protective cap on the pen
- Return the pen to its designated storage location (typically refrigerated)
- Record units used and remaining capacity in your lab notes or tracking sheet
6. Storage Guidelines (Research Stability)
Storage requirements vary by compound and formulation, but in general:
- Store between 2–8°C unless otherwise stated on the label
- Do not freeze unless explicitly allowed by the manufacturer
- Protect from direct sunlight and heat sources
- Keep capped when not in use to avoid contamination
7. Common Handling Errors to Avoid
- Skipping the initial priming step on first use
- Reusing needle tips across different experiments or operators
- Guessing unit values instead of calculating from mg/volume
- Storing pens uncapped or outside of recommended temperature ranges
