Joint Health for Pets—Powered by Human-Grade Science
About FlexPet
FlexPet was created with a simple mission: to help pets move better and feel better, naturally. Whether it’s a senior dog slowing down or a cat struggling to jump like they used to, FlexPet delivers real joint support—without pharmaceuticals or harsh ingredients. Our secret? The same science behind Flexpet, our trusted human joint health brand used by thousands for over 20 years.
But our story didn’t stop there.
Built on Proven Science—Formulated for Pets
FlexPet is powered by CM8® (Cetyl Myristoleate), the same patented compound developed by Dr. Harry Diehl, a researcher at the National Institutes of Health. His decades of work on inflammation and joint mobility led to the discovery of CM8’s powerful benefits. FlexPet brought that discovery to people. FlexPet brings it to pets—with formulations tailored to their needs, sizes, and sensitivities. And just like our human supplements, FlexPet uses only human-quality ingredients. Because your pets deserve nothing less.
“I believe in science that works—and in treating pets like family. FlexPet is built on that belief. I’m honored to carry this mission forward with integrity, compassion, and innovation.”
— Peter St. John, Owner
A Shared Legacy, A New Chapter
In 2024, entrepreneur and joint health specialist Peter St. John acquired both Flexcin and FlexPet. With a background in orthopedic joint replacement sales and a deep passion for preventative care, Peter saw the potential to scale these trusted brands while maintaining their heart.
How It Started
The Beginning
FlexPet began with a grandson’s determination to help his grandmother. Witnessing her daily pain and limited mobility, founder Tamer Elsafy was inspired to search for a better solution. That search led to the discovery of Cetyl Myristoleate (CM8), a compound originally developed by Dr. Harry Diehl, a researcher at the National Institutes of Health.
The Growth
From that moment on, FlexPet grew into a trusted name in joint health. The company earned customer loyalty through real results, genuine compassion, and a foundation in science. CM8 quickly became known for its potential in supporting joint function and reducing discomfort, helping countless individuals regain mobility.
The Science
Dr. Diehl dedicated years to studying natural compounds that could reduce joint inflammation and improve movement. His groundbreaking research led to several patents for CM8’s powerful anti-inflammatory properties. These discoveries became the cornerstone of FlexPet’s joint health formulations, revolutionizing the way we approach joint care.
