People often search for a reusable peptide pen when they mean empty reusable hardware for a compatible cartridge. Grey Depot's pens are supplied as empty hardware. They are not pre-filled products and do not include peptide contents, cartridges or needles unless a listing expressly says so.

Empty reusable hardware vs pre-filled pens

A reusable pen is the hardware, while a pre-filled pen includes its contents as a finished product. The Grey Depot range is empty reusable hardware, so compare the physical format and included accessories rather than assuming a named substance is supplied.

Cartridge compatibility

The current range has three models. All three fit all Grey Depot Standard, Premium and Gold 3 mL glass cartridges. This is a maintained store-range compatibility statement, not a universal claim for third-party cartridges.

What is included with each Grey Depot pen?

The 60-unit Reusable Injection Pen has a clear cartridge chamber and a slim carry case with space for one spare cartridge and three pen needles. The Slim model has a metallic finish and a higher maximum marked setting of 80 units, without a carry case. The Gansulin model has a spring-assisted automatic mechanism and comes with a carry case in its retail box.

Check the maximum marked setting, case or retail-box inclusion, colour availability and live stock on the collection page. A hardware setting is not a substance conversion or dosing recommendation.
