Modern insulin pen for all
GO-Pen® is the first FDA-cleared reusable insulin pen with user-filled reservoir, built for the 20+ million people worldwide still using syringes for daily injections. One pen lasts three years, delivering precise dosing at comparable syringe cost.
Announcement: 7 May, 2025
GO-PEN® receives FDA 510(k) clearance for innovative user-filled insulin pen.
The change
GO-Pen brings
Most insulin leaves the factory in vials—the same affordable format used for decades. But until now, using that insulin meant choosing between expensive pre-filled pens or outdated syringes.
GO-Pen's user-filled reservoir bridges this gap. People fill their own pen directly from an insulin vial, combining pen precision vial affordability. No more daily pharmacy. No more compromised dosing. No more stigma.
Endorsed
by healthcare leaders worldwide
Leading specialists in diabetes care, humanitarian medicine, and government health systems recognize GO-Pen's approach to closing the delivery gap.
“GO-PEN® is the most innovative concept that I have ever seen towards the needs of patients who take insulin using syringes”

“I am very excited about GO-Pen being available, especially in low- and middle-income countries where people really should have the option to be able to use the type of delivery device that they wish to. What stands out for me is that it's a universal device.”
— Nupur Lalvani, Founder of Blue Circle Foundation, India
The global
diabetes challenge
Addressing the inequity
While insulin pens have been available since the 1980s, cost barriers mean millions still rely on syringes, particularly in low- and middle-income countries where 86.9% of people with undiagnosed diabetes live.
GO-Pen addresses this gap by making modern pen technology accessible at comparable syringe cost—democratizing diabetes care for the millions left behind.
589 million adults worldwide live with diabetes — that's 1 in 11 people. 20+ million people with diabetes still use syringes instead of modern insulin pens. 252 million adults with diabetes remain undiagnosed globally. Over $1 trillion was spent on diabetes care in 2024 — 12% of global health expenditure. 3.4 million people died from diabetes-related causes in 2024.

It’s time
to move beyond syringes
Syringe dependency shouldn't be the only option in 2025. Millions worldwide face this choice daily: expensive pre-filled pens or outdated syringes. GO-Pen changes this - delivering pen precision at comparable syringe cost.
