It's not the cheapest option out there, but for researchers who need consistent dosing without fuss, teh spring-driven twist activation actually works better than most budget pens we've tested.
We've been using these for our retatrutide studies, and honestly, the audible click when the dose is delivered is a nice touch—you know exactly when it's done without looking.
The 3ml cartridge size is standerd, and bayonet connection makes swapping them out pretty quick (usually under 10 seconds), though you'll want to avoid overtightening or it can jam.
Color options are blue, pink, green, grey, silver, or light blue, but most buyers go with the grey or silver for a cleaner lab look, and logo printing is avaliable if you're ordering a batch.
2-year shelf life is fine for most labs, but we usually have stock, so confirm lead time if you need a rush—we've seen 20 days or so on custom colors.
It's CE and ISO13485 certified, so compliance is sorted, but don't expect it to work well with every thick peptide formulation; thinner solutions are better for this spring-driven mechanism.
We offer Blue, Pink, Green, Grey, Silver, and Light Blue. You can choose any color for your order — no minimum color mix required.
Yes, we can print your logo on the pen body. For custom logo printing, the MOQ is typically 1000 units, but we can discuss smaller runs depending on your needs.
The pen is CE, ISO13485, and GMP certified. We can provide copies of these certificates with your order.
It's a spring-driven pen with twist activation — you twist the base to set the dose, then press the button to inject. The 3ml cartridge can be filled with Retatrutide or other peptides, but we supply it empty for research use.
Lead time is usually 15-20 working days after order confirmation. Each pen comes in a sterile blister pack to keep it clean and ready for filling.
