How a typical cycle is structured over time (for reference).
Start low and step the dose up every few weeks so your body adjusts comfortably. Reconstitute once, then draw more units as you climb.
No mixing needed. Dial the pen to the number of clicks shown, then press to inject. 1 click = 0.1 mg.

Storage
- Avoid freeze-thaw cycles
Technique
- Clean the vial stopper and the skin with an alcohol swab and let both air-dry.
- Pinch a skinfold and insert the needle at 45–90° into the subcutaneous tissue.
- Do not aspirate for subcutaneous injections. Inject slowly and steadily.
- Wait 5–10 seconds before withdrawing, then apply gentle pressure. Do not rub the site.
- Rotate sites between the abdomen (at least 5 cm from the navel), thighs and upper arms to avoid lipohypertrophy.
- Use a new sterile 28–31 G insulin syringe every time and dispose of it in a sharps container.
