V3 Auto-Injection Pen Kit — Precision Volumes, Anywhere
The V3 auto-injection pen kit is the reusable pen that MyGLP1Store’s retatrutide, tirzepatide and semaglutide 3cc prefilled cartridges are built for. Each kit includes two V3 click-dial pens with clear graduated cartridge chambers, precision dial adjustment, pen caps and a rigid magnetic-close travel case that keeps everything protected and organised in the lab or on the road.
What’s in the Kit
- 1 V3 reusable auto-injection pens with click-dial volume control
- Clear graduated cartridge chamber on each pen for visual confirmation of the loaded cartridge
- Protective magnetic-close hard travel case
- Pen caps for secure storage between uses
Why Researchers Choose the V3 Pen
- Precise: fine dial increments for repeatable, accurate volumes from a prefilled cartridge.
- Reusable: durable construction designed for long-term use — swap cartridges, keep the pen.
- Portable: the compact case fits in a bag, a drawer or a refrigerator door.
- Discreet: low-profile matte black design.
- No reconstitution: pair it with a prefilled 3cc cartridge and there is no bacteriostatic water, no syringe and no measuring by eye.
