The V3 is our closed-cap reusable pen, machined from solid aluminum on the same slim body and dial system as the V1 - accurate, simple to load, and comfortable to hold. You get a complete peptide pen starter kit with every V3 - the pen, a 3mL cartridge, and the tools to start the same day you receive it.
 
It holds a 60-unit range and dials true - one click, one unit, every time. It runs on a standard 3mL cartridge, and it is reusable: when a cartridge runs out, you swap the cartridge, not the pen. Every V3 ships with 1 cartridge to get you started.
 
Unlike the open-cap V2 and V2.5, the V3's closed cap means you will see the needle as you inject - the setup many experienced users prefer.
 
We recommend purchasing Spacers with this model to get every last bit of liquid out of your cartridge.

Load any 3mL short-stopper cartridge and the V3 handles it the same way - it is built for the research peptides our customers run most, including BPC-157, TB-500, GHK-Cu, CJC-1295, Ipamorelin, Tesamorelin, MOTS-c, and NAD+. For research purposes only.
