Hi, I'm Christopher Walker.

I am the founder and CEO of UMZU, and the author of the Thermo Diet. I got my degree in neuroscience from Duke University. I believe that the human body is a self-healing organism, and that we need to allow the proper nutrients and lifestyle in order to help it heal itself from the inside out. I'm happy when I'm learning something new, and I love to distill complex concepts into simple, easy-to-understand ideas.

About me

My journey as a health entrepreneur has been incredible, with plenty of ups and downs. That being said, it's been my life's work to bring health and good business practices to the world - and I'm just getting started!

About me

My story (in a nutshell)

2008: Brain tumor diagnosis

I was diagnosed with a brain tumor. Instead of doing surgery or being on pharmaceuticals for the rest of my life, I decided to heal myself naturally. And it worked!

2012: Launched my blog

I started my first blog, and launched my first book - Testshock - to help men with their health via natural hormonal optimization.

2015: UMZU was born

Born out of a huge need for effective and ethical supplements, UMZU was launched first as Testshock supplements, then Truth Nutra, then rebranded to UMZU.


My promise

Whether it's with UMZU, Thermo Diet, or anything else, I strive to provide the highest quality truly valuable products, services, and educational information to the world. It's my life's mission.


Naturally made

Ethical sourcing practices, such as sustainable harvesting and fair trade partnerships, promote environmental stewardship and social responsibility. Rigorous testing for purity, potency, and contaminants guarantees consumer confidence. Transparent labeling and documentation of sourcing information further enhance credibility, empowering consumers to make informed choices.


Completely cruelty-free

Cruelty-free supplement ingredients are sourced and manufactured without any harm or testing on animals. These ingredients are derived from ethical and sustainable practices, ensuring the well-being of both animals and the environment. By choosing cruelty-free supplements, consumers can support products that align with their values of compassion and promote a more humane approach to ingredient sourcing in the supplement industry.


Ingredient sourcing

Effective supplement ingredient sourcing is crucial for ensuring product quality and safety. It involves meticulous research and careful selection of reputable suppliers and manufacturers. Thoroughly vetting suppliers' certifications, quality control processes, and sourcing methods guarantees the use of premium, traceable ingredients.


Environmental impact

We need to do our part to take care of the environment every chance we get. Taking care of the environment is a responsibility that rests upon each and every one of us. It is essential for our well-being and the preservation of our planet for future generations. By adopting eco-friendly practices, we can contribute to a cleaner, healthier, and more sustainable world.
