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 orharmless substances and cause allergies and autoimmune diseases.

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 against the herpes virus that causes cold sores and genital herpes (herpes simplex virus or HSV) 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.

The result is 60% fewer cold sore outbreaks (and the fewer outbreaks that happen are less severe).

But the mechanism of action is not specific for cold sores or the herpes virus. Square-Immune® just improves immune function.

"At the time I invented this, I was having almost constant cold sores,  but now I have not had even one in over five years.  I also, at least once a year, had a pretty bad cold, and  now I have had one mild cold in five years. Other people report less severe allergies and reduced symptoms  of long COVID and fibromyalgia."

- Hugh McTavish,  PhD Biochemist & Inventor of Square-Immune®.

What is SADBE™?

SADBE™ (Squaric Acid Dibutyl Ester), the active ingredient of Square-Immune®, is a topical immunosensitizer, like poison ivy, and has been used medically for 40 years in various immune conditions. Square-Immune® was used in placebo-controlled clinical trials at Harvard and Stanford and other sites in 140 patients, and it cut cold sore outbreaks by 60%.

Clinical Trial Results:

● Square-Immune® tripled time to the next cold sore outbreak vs. placebo.

● Square-Immune® cut the number of outbreaks by 2.6x vs. placebo.

● Square-Immune® shifted the immune response to herpes virus from an antibody response to a stronger, T-cell response. 

● Square-Immune® increased production of anti-viral protein Interferon-Gamma (produced by T-cells) by 1,100% indicating strong immune response!

"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!"
