Tirzepatide Pen Cartridge — 3cc Prefilled & Sterile
The tirzepatide pen cartridge from MyGLP1Store is a 3cc prefilled, sterile auto-injection cartridge preloaded with research-grade tirzepatide and vitamin B12, engineered to seat directly into the V3 auto-injection pen. No reconstitution, no bacteriostatic-water step, no vial transfers and no measuring — a ready-to-use tirzepatide auto-injector cartridge for streamlined, repeatable laboratory research workflows. Third-party tested, >99% purity, same-day US shipping.
Why a Prefilled Tirzepatide Pen Cartridge?
- Prefilled and sterile: ships ready to use in a sealed 3cc cartridge — no reconstitution and no bacteriostatic water required.
- V3 pen compatible: drops straight into the V3 auto-injection pen for precise, repeatable research volumes.
- Tirzepatide + B12: preloaded with research-grade tirzepatide and vitamin B12 in one solution.
- Third-party tested: identity, purity and concentration verified by an independent laboratory before release.
- Same cost as the vial: each cartridge size is priced in line with the equivalent lyophilized tirzepatide vial — nothing extra for the prefilled format.
What Is Tirzepatide?
Tirzepatide is a long-acting synthetic dual agonist studied at the GIP and GLP-1 receptors — one of the most closely examined compounds in metabolic and endocrine signalling research. In the prefilled cartridge format it is supplied as a sterile solution for the V3 auto-injection pen rather than as a lyophilized powder. For the powder format, see the tirzepatide vial listing; for background on the compound, read the tirzepatide research guide.

Frequently Asked Questions
What is a tirzepatide pen cartridge?
A sealed 3cc cartridge prefilled with a sterile tirzepatide and B12 solution, designed to load into a reusable V3 auto-injection pen. It replaces the vial, bacteriostatic water and syringe steps of the lyophilized format with a single ready-to-use cartridge.
Does the cartridge need to be reconstituted?
No. It ships prefilled with the solution already prepared. Nothing is added to it.
Which pen does it fit?
The V3 auto-injection pen. The cartridge is not designed for other pen models.
How is the cartridge stored?
Refrigerated at 2–8°C, protected from light, and never frozen. Keep it sealed until it is loaded into the pen.
