2-Steps Activation Autoinjector Prefilled Syringe Safety System for Diabetes and GLP-1 Treatments

It's not designed for anything above 20 cP viscosity, which basically rules out most oil-based depot formulations—that's the main caveat here, and it's worth knowing upfront if you're working with thicker suspensions.

For the GLP-1 analogs and insulin we're dealing with, though, that viscosity ceiling is fine since Semaglutide and liraglutide formulations typically sit well under 10 cP, and the 2.25ml fixed-dose prefilled syringe handles the common 0.5mg to 2mg doses without issue.

The needle cover push-on-skin activation is pretty much foolproof for one-handed use—we've tested it with 27G and 29GTW needles, and the 6±2 mm subcutaneous depth is consistent enough for most diabetes protocols, though you'll want to verify with your specific drug's injection site requrement.

Audible, visual, and tactile feedback all trigger at end of injection; the passive locking cover permanently hides the needle afterward, which is a solid safety feature for handling compliance (usually 2-4 weeks for custom color or grip options, but check lead time on that).

We're ordering HL002 because of that it's better than the standard spring-loaded autoinjectors for fixed-dose GLP-1 therapies—teh 22*22*159.2mm form factor fits in a standerd pen case, and the medical-grade plastic body holds up to routine drop tests without cracking.
