3ml Adjustable Dose Weight Loss Injection Pen for Diabetes and Medical Aesthetics

Managing multiple daily injections for diabetes or weight loss can be a hassle when you need consistent accuracy without complicated setups, and patients often struggle with dosing errors or discomfort from standard syringes.

This pen solves that by combining a precise mechanical dial with an auto-injection mechanism that delivers doses between 0.01ml and 0.6ml in under six seconds, and you get both a visual marker and an audible click to confirm the shot is done right.

The 3ml cartridge fits a 31G or 32G needle, outer diameter is 17mm, and the cartridge inner diameter is φ9.7mm, so it works with common GLP-1 agonists like liraglutide and tirzepatide as well as insulin, while teh whole thing is made from medical-grade plastic and comes in grey or blue.

It carries China Class II Medical Device certifcation and the CDE packaging is recorded, which means regulatory paperwork is already in place for distribution in many markets, and honestly, that saves a lot of back-and-forth with compliance teams.

Custom labeling is available if you need your own branding on the pen, and since it's a disposable single-use design, there's no need to worry about cleaning or reordering reusable parts.

Supply is steady form the manufacurer with typical lead times around four to six weeks, and minimum order quantities are reasonable for both small clinics and larger distributors.
