The Science-Backed Ingredients That Make Cellular Regeneration Possible
Each ingredient was selected based on clinical research and proven ability to support your dog's natural repair systems. This isn't guesswork—it's pharmaceutical-grade precision.

(Proprietary Blend)
Xcellara™
The breakthrough formula that increases circulating repair cells by 281%. Seven years of development by Harvard Medical School-trained researchers created this cellular regeneration activator.

Astragalus Root
Adaptogenic herb that boosts immune resilience and supports the body's natural ability to resist cellular damage while promoting healthy aging processes.

Blue-Green Algae (AFA)
Rich in stem cell mobilizing compounds and antioxidants that support cellular health and provide the raw materials your dog's body needs for repair and regeneration.

Rhodiola Rosea
Powerful adaptogen that enhances energy production at the cellular level and helps your dog's body adapt to physical and environmental stress more effectively.

Panax Ginseng
Supports cognitive function and mental alertness while providing sustained energy through improved cellular metabolism and circulation throughout the body.

Cordyceps Mushroom
Enhances oxygen utilization and cellular energy production, supporting improved stamina, recovery, and overall vitality in aging or low-energy dogs.

Spirulina
Nutrient-dense superfood that provides essential amino acids, vitamins, and minerals needed for optimal cellular function and tissue repair throughout the body.
One Revolutionary Chew.
Five Life-Changing Benefits.
PawPa™ Regen is the only dog chew that addresses aging through multiple cellular mechanisms simultaneously, delivering comprehensive wellness support your dog can't get ANYWHERE else.
Appearance
Shinier Coat, Brighter Eyes
Increased repair cells rebuild damaged hair follicles and clear up that cloudy, tired look in their eyes and fur.
Performance
Longer Walks, Easier Movement
More stem cells mean faster joint repair and muscle recovery—no more stopping halfway through walks.
Behavior
Playful Energy Returns
When their body stops hurting, dogs naturally become more active and seek out play again.
Attitude
Alert and Engaged Again
Better circulation and cellular repair improve mood and interest in their surroundings.
Responsiveness
Follows Commands Like Before
Enhanced brain cell function restores the sharp, attentive dog who used to hang on your every word.
"Stem cells are your dog's natural repair system. When we can activate them, we unlock the body's own ability to heal and reverse the damage that comes with aging."

Learn About Our Science
You've Got Questions?
We've got answers.
How long will it take to see results in my dog?
Most dogs show noticeable improvements in energy and behavior within 3-4 weeks. Significant changes in mobility, coat quality, and overall vitality typically appear by week 4, with peak benefits at 6 weeks.
Is this safe for my dog to take long-term?
Absolutely. PawPa™ Regen has been tested extensively with zero adverse effects reported across multiple species.
Humans
Horses
Pigs
Mice
Dogs
Will my dog actually eat these chews?
Yes! We've formulated PawPa™ Regen taste just like beef! In our trials, 98% of dogs eagerly consumed their daily chew. If your dog doesn't love the taste, we'll refund your purchase completely.
What if my dog is really old - will this still help a 15-year-old dog?
Absolutely. Age is actually when this works best because older dogs have experienced the biggest drop in natural stem cell production. Our studies specifically focused on senior dogs and showed remarkable improvements regardless of age. A 15-year-old dog's body still contains all the repair mechanisms they were born with—they just need reactivation. In fact, the older your dog, the more dramatic the improvements you're likely to see because there's more repair work to be done.
How is this different from other dog supplements?
Traditional supplements provide vitamins and nutrients that support your dog's current health level, but they can't repair existing damage or reverse aging. PawPa™ Regen stimulates your dog's body to produce more stem cells—the specialized cells responsible for rebuilding damaged tissue throughout the body.
While other products maintain the status quo, this formula actively restores your dog's natural repair capabilities that decline with age. It's regenerative medicine that was previously only available through expensive veterinary procedures, now delivered in a daily chew.
What if it doesn't work for my dog?
We offer a 90-day money-back guarantee because we're confident in our results. If you don't see visible improvements in your dog's energy, mobility, or overall wellness within 6 weeks, contact us for a full refund—no questions asked.

Do I need to give this forever or just for a certain period?
Think of this like any essential vitamin your dog needs daily. Just as you shower every day to stay clean, aging dogs need daily stem cell support to maintain their repair systems. When you stop giving PawPa™ Regen, your dog's stem cell production returns to its previous declining levels, and the repair process slows down.
For sustained quality of life improvements, consistent daily use is key—it's not a one-time fix, but ongoing support for your dog's natural healing abilities.
This sounds too good to be true - what's the catch?
The only "catch" is that it requires consistent daily use and realistic expectations. This isn't a miracle pill that instantly fixes everything—it's a way to restart your dog's natural repair system.
The stem cells we help generate will heal and improve your dog's health, but if your dog has conditions that prevent even their own stem cells from working effectively, we can't override that.
What we can do is give your dog's body the best possible chance to heal itself naturally.
What proof do you have that this actually works?
We have rigorous clinical evidence: randomized, double-blind, placebo-controlled trials conducted by Harvard Medical School-trained researchers, veterinarian-supervised studies showing measurable improvements in dogs, and safety testing across multiple species with zero adverse effects reported.
This isn't based on testimonials or hope. It's pharmaceutical-grade research proving the formula works exactly as intended.
