Inward-Rotation GLP-1 Pen Injector

Internal Rotation Mechanism • Precise Dose Control • Designed for GLP-1, Peptides & Therapeutic Compounds

The Inward-Rotation GLP-1 Pen Injector is a next-generation adjustable-dose injection pen engineered specifically for GLP-1 therapies (Semaglutide, Tirzepatide, Liraglutide), peptides, and other multi-dose injectable formulations. This pen features a high-accuracy internal rotation dose mechanism, providing stable, controlled, and reliable dose adjustments with each use.

Its modern blue body, ergonomic structure, and transparent cartridge window make it ideal for wellness programs, metabolic clinics, compounding pharmacies, weight-management brands, and home-use therapy patients.

Product Overview

This internal-rotation injection pen adopts a hidden dose-selection mechanism, activated by twisting the rear dial. The inward rotation structure ensures smoother dosing, firm tactile feedback, and higher mechanical stability compared to traditional external-dial systems.

Designed with a visible cartridge chamber, medical-grade materials, and a comfortable grip, it enables both professional clinicians and new users to administer GLP-1 injections with confidence.
