The story behind everything

How Biscut's Second Chance

Became Nzymes' First Breakthrough.

Stan didn't set out to build a company. He set out to help his dog. What happened next changed thousands of lives — and it all began in a shelter on the island of Oahu.

Biscut
Oahu, 1992

A shelter dog.
A man who wouldn't give up.

In the summer of 1992, Stan Stansbury walked into an animal shelter in Oahu and found a small white Japanese Spitz. She'd been confined for four months under Hawaii's quarantine laws — depleted, stressed, and not in good shape. But when Stan approached, she stood up on her hind legs and danced for a treat: a dog biscuit he had brought with him.

He brought her home that day, and of course, he named her Biscut.

That first night, she suffered nine neurological episodes. Stan stayed by her side through every one — holding her, comforting her, unwilling to accept that this was just how things were going to be.

"It always pained me to see her have a fit. She averaged 3 to 4 fits every month, and I wanted to do something to help her resolve this issue."

— Stan Stansbury, Co-founder

The discovery

Give the body what it needs.
Watch what it does with it.

Stan got to work. He studied every label, every ingredient in her food and treats. What he found was shocking: sugars, chemicals, dyes — even in the "good" stuff. He threw it all out and switched her to real, clean food. And with his brother Thomas, they started working on a natural supplement: something alive, rich with nutrients, and easy to absorb.

They gave it to Biscut first. And she changed. Her seizures stopped. Her coat came back. Her energy returned. Biscut lived another 17 years, passing peacefully at the age of 19. In her final eight years, she had only one seizure.

What Stan discovered wasn't a drug or a medical procedure. It was nutrition — real, live, enzyme-active nutrition that commercial pet food had been cooking out of existence for decades. Sprouted soy. Live enzyme activity. Food-based antioxidants that worked at the cellular level.

He gave Biscut's body the tools it needed to thrive. And her body did the rest.

The journey

From one dog's recovery
to a million pets helped.

Stan didn't rush. He researched, tested, and refined for years before sharing what he'd found with the world.

1992
Biscut comes home

Stan adopts a Japanese Spitz from a shelter in Oahu. That night, she has nine neurological episodes. Stan begins researching pet nutrition in earnest — scrutinizing ingredient labels, vet-recommended formulas, and commercial brands. What he finds shocks him: most pet food is filled with sugar, synthetic additives, and inflammatory ingredients.

1992–94
Nutrition as foundation

Stan overhauled Biscut's diet — eliminating processed ingredients, focusing on whole foods. Over time: fewer episodes, more energy, a brighter coat. The conviction formed: when the body has what it needs, it can do remarkable things.

1995
The formula takes shape

Stan's brother Thomas acquires exclusive rights to a live superfood protein formula — packed with enzymes, nutrients, and bioactive compounds. The brothers see an opportunity: build something real, for the families who need it most.

1997–98
From formula to product

Working with local pet stores and a veterinarian, Stan and Thomas develop and refine the Antioxidant Treat formula — combining live superfood protein with food-based vitamins A, C & E, selenium, and beef liver for palatability. Biscut tries them first.

1999
Nzymes is born

Stan and Thomas officially launch BioPet Inc. and Nzymes.com. The mission was simple: give other families what Biscut had found. Real, whole-food nutrition that supported the body the way it was designed to work.

2000s
The product line grows

Bac-Pak Plus, Ox-E Drops, Tracite Minerals, and Black Leaf Tincture are added — each one rooted in the same foundational philosophy: give the body what it needs and trust it to do the rest.

Today
27 years. 1 million pets. Same mission.

Now in its third generation, Nzymes is still family-owned, still independent, and still rooted in what Stan discovered for one small white dog in Oahu in 1992.

Biscut's legacy

In her final eight years of life, Biscut experienced only one neurological episode. She remained active, alert, and mobile into her senior years — and passed away peacefully at 19.5 years old.

She became the proof and the purpose. The reason Stan picked up the phone for every family who called. The reason the company exists at all. And the reason, 27 years later, we still believe: when the body has what it needs, it can do remarkable things.

What we believe

We don't mask.
We don't rush. We support.

The pet health market is saturated with products designed to suppress symptoms. We've never been interested in that. Everything we do traces back to the same question Stan asked in 1992: what does the body actually need to function the way it was designed to?

The answer is still the same: live nutrition. Whole-food enzymes. Minerals. The building blocks the body was designed to use — that modern diets and modern medicine have stripped away.

God & Family First
Every decision we make starts here. Our values aren't a marketing line — they're how we actually run this company.
Help Others Thrive
We pick up the phone. We answer emails. We genuinely want your pet to get better — not just to make a sale.
Act With Integrity
We don't add products to our line unless they have a genuine purpose and are worthy of the Nzymes name. That's been true since 1999.
Powered by Nature. Proven by Pets.
Over a million transformations later, we still believe what Stan believed in 1992: give the body what it needs and trust it to do the rest.
