"The relief that I am getting from Square Immune is above and beyond what I have expected. Words cannot express my gratitude. I have HSV1 oral, had at least 3 outbreaks per month, & my outbreaks were severe. Your product is working."

"Since using Square-Immune, I've had zero...yes, ZERO outbreaks. It's been almost 2 years now. I no longer carry the emotional weight that came along with those outbreaks. To say I have my life back is an understatement!"

"Before dosing with 2% SADBE, I would get weekly genital herpes outbreaks like clockwork. After 3 weeks from dosing, I noticed my outbreaks were becoming much less severe, and after 6 weeks from dosing, my outbreaks have completely stopped. I now have my life back, and no longer think about HSV on a daily basis. Thank you so much"

"After application I had a small outbreak on my lip but it was gone pretty quickly. And the interesting thing is when the outbreak happened the application spot on my arm got a mild rash, which I think shows the immune system is responding to the virus more. I'm definitely buying the year supply!"

HOW IT WORKS

Square-Immune® is topically applied to a hidden spot under your arm and it causes an immune response in your skin—the same immune response as poison ivy.

Poison ivy and Square-Immune® both basically trick your body into thinking that your skin is a foreign object and mounting an immune response against your own skin.

Square-Immune® resets your whole immune system. We evolved to encounter things like poison ivy on a regular basis, so our bodies are adapted to that. Now we live these sterile indoor lives and shelter our immune systems from every challenge. The result is weak and confused immune systems that don't know how to fight a real virus and instead attack our own bodies or harmless substances and cause more frequent and more severe symptoms of Long-COVID, Fibromyalgia, & Chronic Fatigue.

The active ingredient in Square-Immune® is squaric acid dibutyl ester (SADBE™).

We have found in clinical trials that Square-Immune® shifts the immune response from a Type-2 immune response based on antibodies to a Type-1 immune response based on T cells. T cells are the cells depleted in AIDS, so that tells you how important they are. They are much more effective than antibodies when treating & preventing Long-COVID, Fibromyalgia, & Chronic Fatigue.

The result is fewer & less severe Colds & Flu.

But the mechanism of action is not "just for Colds & Flu," Square-Immune® improves your entire immune function.

How to Apply Square-Immune™

See how easy it is to apply Square-Immune™ and start preventing the distressing symptoms of Long-COVID, Fibromyalgia, & Chronic Fatigue today!

One dose improves immune response for three months so we recommend applying it once every three months. Some customers find that applying additional doses between their regular three-month applications works even better. If you want to apply additional doses, we recommend the 1-year supply, which is a larger amount of Square-Immune™ that allows you to apply doses when you want.
