Peptide Injection Pen - Disposable Plastic

Note: this pen ships empty. You'll need 3ml Peptide Cartridges and Pen Needles (both sold separately) before it's ready to use — the needle should be changed regularly.

A lower-cost, plastic injection pen for dialing an exact, repeatable dose — the disposable alternative to our reusable metal pen.

Prefer buying in bulk? See our Disposable Pen Pack.

Why you need it: A budget-friendly option if you want a spare pen on hand, or you're not ready to commit to the reusable metal version. Same precision dial, lighter plastic build.

How to use it: Load a 3ml peptide cartridge into the barrel, screw on a pen needle, dial to your required dose, inject, then remove and safely dispose of the needle in a sharps container. Change the needle regularly.
