PepPens Reviews 

Written by the company

PepPens® is an American company that makes reusable and disposable injection pens and the accessories that go with them. All of our products are sold for research use only. We're based in Redmond, Oregon, and every order ships from our fulfillment center in Lincoln, Nebraska. Our pen lineup includes the PepPen V1, V2, V2 Pro, V3 and the Disposable PepPen. Each one uses a standard 3 mL glass cartridge and dials in 0.01 mL steps, which is one unit on the U-100 scale. The V1 delivers up to 80 units per press and the rest deliver up to 60. The V2 is our most popular pen. The V2 Pro pairs the twist-lock loading of our V1 build with the V2's open spring end. The Disposable PepPen is built for one cartridge, start to finish. We also carry everything needed to use them: glass cartridges, pen needles supplied in factory-sealed sterile packaging by the manufacturer, reconstitution water, cases and starter kits. We want every customer to know exactly what they're getting. Our website has a free fill guide, a side-by-side pen comparison, a peptide pen calculator, and an FAQ with how-to videos for each model. US orders over $59 ship free, and we ship to Canada too. Every pen is covered by a 6-month warranty, we offer 30-day returns, and customers earn rewards points on every order. More than 3,300 customers ordered from us in 2026. When you email us, a real person on our team answers.See more
