“Is Your Insulin as Safe as You Think It Is?”

In the battle against diabetes, every drop matters.

However, there’s one thing in the diabetic community that has been missing -

damaged insulin is real!

Keep reading to see why…

When exposed to high or low temperatures that are common in everyday life, insulin can become damaged and lose some of its effectiveness.

The shocking thing is that this lost potency of insulin can’t be seen with naked eyes, nor can it be felt in the moment of injection .


In simple terms, what is supposed to help you might have now -

become a liability.

Today, millions of Americans are at risk of taking damaged insulin. Any moment, anyone can be a victim. It is important then to understand why ineffective insulin should never be taken lightly. Here’s why.

Everyday, There’s A Huge Chance Your Insulin Gets Damaged

You probably remember that at some time your diabetic educator or pharmacist told you that you should store your insulin properly and make sure that you’re either not exposing it to temperatures above 86° F, or allow it to freeze.

If these aren’t met, the insulin then loses its potency and has the potential to put you or your loved ones in harm’s way - by making your insulin intake underdosed which leads to hyperglycemia, or overdosed which leads to hypoglycemia.

Next Time You Won’t Be So Lucky…

Both attacks, if not treated immediately, will lead you straight to the Emergency Room. The “best-case” scenario is that you only have blurred vision, headache, fatigue, and nausea.

The worst case?

You could experience vision damage, organ failure, loss of consciousness, slurred speech, confusion, and the worst of it all, the risk of a coma!

All because of bad insulin?

“Can you imagine how it feels to stay alive and yet becoming disabled and permanently reliant on help to get by? Can you imagine the ruined lives of you and your family?”

And so our solution was very straightforward - keep insulin from being ineffective and damaging by making it as protected from external temperatures as possible.


This can range anywhere from traffic jams, to walking in the park, to playing in the heat of the sun - normal, day-to-day occurrences that can make your insulin impotent.

We’ve spent countless hours of research and tests to create a fool-proof, 100% damage-free insulin that, no matter whether you’re in the Sahara Desert or in the North Pole, your insulin is still as good as new.

Thousands of Satisfied Customers!

I purchased it for my son, so his insulin is kept cool while he's outside. It's very convenient since he does not have to do anything !:) It is really small, sits inside his bag and when I checked it, the insulin was cool. Keeps him safe and that's what matters.

- Omar Spence

“I've studied the cooling bags and when I learned about this one, I was skeptical. The cooling bags did not work for me, is this one any different? Well, the short story is that it works. If you continue reading, you'd find out why I say that. First I've measured the temperature of the insulin with one of these infrared thermometers. When it was 110F outside the insulin was at 81F ! that's below the limit of 86 and it stayed like that for hours! Second

- Camile Khakinov

I've asked my nursing professor about this product. She is in fact using it and highly recommends it. Just replace the pen cap with this one and you're good to go, nothing else to do and the insulin is kept cool. This can stay on your pen since it is very small and doesn't take space.

- Ruby Boone

I have been a diabetic my whole life and the effort that it takes to carry around my insulin and ensure that it is kept at a safe temperature can be a difficult process. My parents recently bought me the MY VIV CAP to make transporting my insulin a lot easier to manage. I can now just keep my insulin easily in my pocket or work bag. Would highly recommend this product.

- Sylvia Halton
