What is the clip-on lid for?

The V3 pen has a clip-on lid with an integrated carry clip, so you can secure the pen in a case, coat pocket, or storage pouch. See the V1 vs V2 vs V3 comparison for how the generation labels are used by sellers.


What should you check when comparing pen bodies?

Pen bodies from different sellers vary in materials, lid design, colour range and what is included, so it helps to compare the listings on the same points: the body material, how the dial works, the lid, the cartridge size it takes, and the seller's returns terms. Our Peptide Pen UK: The Complete Buyer's Guide covers this in more detail.

The V3 pen body is sold as an empty hardware accessory only. It does not contain any liquid, compound, medication, or consumable substance. It is not supplied with needles. It takes standard 3mL cartridges, which are sold separately, and is sold strictly as an accessory.
