AIM Activation
Activates AIM to Support Body's Natural Cleanup System
Is Your Cat’s Kidney Disease Getting Worse?
If your cat’s kidney values are rising, now is the time to begin the care that matters—before it’s too late.
A loss of appetite, low energy, and steady weight loss aren’t always signs of aging.
They can be signs that kidney cells are breaking down, one by one.
AIM: A Cleanup Switch That Doesn’t Work in Cats
AIM is a protein that helps clear damaged cells and waste from the body. But in cats, AIM doesn’t function properly.
When this system is inactive, waste begins to accumulate in the kidneys—leading to inflammation, tissue damage, and the progression of kidney disease.
You can think of AIM as the switch that activates the body’s internal cleanup system.
The problem is, in cats, that switch stays off.
At Greycoat Research, we turned our focus to the potential of AIM—and how supporting it could change the outlook for cats with kidney disease.
Dr. Toru Protocol: Formulated for AIM Support
Designed by Dr. Toru Miyazaki of the Institute for AIM Medicine in Japan
Dr. Miyazaki is internationally recognized for his groundbreaking research on AIM and its role in waste clearance.
His theory became the foundation for this Dr. Toru Protocol, a kidney supplement developed to help support AIM activation in cats.

Customer Reviews
I've been giving my cat Protocol for almost 2 weeks. Maybe after she's had her labs done, I can say if Protocol has made a difference. However, her energy level seems good & she takes Procol well in her food.
Our cat Apollo is FeLV+ and, as a result, developed renal pelvis dilation, which led to chronic kidney disease (CKD), stage 2. Before starting treatment with GreyCoat Research products, his blood tests showed urea levels at 113 mg/dL and creatinine at 2.3 mg/dL. He also often experienced anemia, as his kidneys are impaired in producing the hormone that stimulates red blood cell production.
After almost two months of using the Dr. Toru Protocol and the Intensive Protocol, with one capsule daily, we’ve already noticed significant improvements in his energy levels. He’s much more active, climbs (which he never did before), and his blood tests have shown positive changes! While his creatinine levels haven’t decreased yet, his urea has dropped to 94.3 mg/dL, and, most surprisingly, he is no longer anemic - for the first time in two years!
We plan to continue the treatment and run new tests next month to monitor his progress. We are so grateful to have found GreyCoat Research! Congratulations on developing such effective products, and thank you for the online support!
Best regards,
Cybelle
Moosya and her CDK stage 3
Moosya is 19. In November 2024 she was diagnosed with CKD stage 3. She lost weight, appetite and her hair around the neck was falling out. The vet said to think about euthanasia. I started searching for help and found Dr Toru. It is 4 weeks since I started giving Moosya Dr Toru Protocol twice a day.
She put on weight, her hair has improved, and she is even playing with me.
I am going to order more of Dr Toru supplements.
Thank you very much.
Elena.

FAQ
Is Dr. Toru Protocol safe for cats with kidney disease?
Yes. Dr. Toru Protocol is an AIM-based supplement designed specifically for cats with renal conditions, including early and moderate stages of kidney disease. It supports natural waste removal and helps maintain long-term renal stability through a targeted amino acid complex.
Does Dr. Toru Protocol really help with kidney disease in cats?
Yes. Dr. Toru Protocol has been used in over 1,000 consultation cases at Greycoat Research, where cats with kidney disease—particularly those in stage 2 and 3—have shown improvement in creatinine, BUN, and overall health and energy. Among these cases, 97% experienced positive changes when supported with this AIM-based approach.
The supplement targets one of the root causes of kidney decline: the accumulation of waste in the kidneys. Developed in collaboration with Dr. Toru Miyazaki and based on his AIM protein research, it helps activate a cat’s naturally inactive AIM response to promote waste clearance and reduce inflammation. Dr. Toru Protocol is also commonly used alongside prescription diets and other renal support strategies.
How is Dr. Toru Protocol different from other supplements for cat kidney disease?
Unlike general renal support supplements, Dr. Toru Protocol is the only formula based on AIM protein research and developed with guidance from Dr. Miyazaki himself. It’s also informed by real-world data from over 1,000 cats receiving consultation through Greycoat Research. Rather than focusing only on symptom relief, the supplement is designed to support the natural removal of kidney waste—an underlying factor in the progression of kidney disease.
Can I use Dr. Toru Protocol alongside a prescription kidney diet or other supplements?
Yes. Dr. Toru Protocol is compatible with veterinary kidney diets and most renal supplements. However, if your cat is receiving multiple products for urinary or metabolic support, we recommend consulting Greycoat Research to ensure a balanced and appropriate care plan.
When should I start giving Dr. Toru Protocol to my cat?
As early as possible. Starting Dr. Toru Protocol early helps support kidney function before waste buildup progresses, making it easier to maintain stability over time. Cats with kidney disease often show no symptoms until later stages, but routine blood tests may reveal elevated creatinine or BUN levels long before visible signs appear. Dr. Toru Protocol is also suitable for senior cats or breeds prone to chronic kidney conditions.
How do I give Dr. Toru Protocol to a picky cat or one that won’t take pills?
Dr. Toru Protocol is designed to be easy to give, even for picky or sensitive cats. The capsules are small and smooth, making them easy to swallow on their own—but they can also be opened and the tasteless, odorless powder mixed into food. Whether your cat prefers capsules or powder, both options allow for consistent and stress-free supplementation.
Should I give Dr. Toru Protocol even if my cat seems healthy?
Yes. Dr. Toru Protocol can be used as a preventative supplement to support kidney health before any problems appear. Many cats, especially as they age, begin to accumulate waste in the kidneys long before symptoms are noticeable, so early support can make a meaningful difference over time.
Is Dr. Toru Protocol the same as Dr. Miyazaki’s AIM injection for cats?
Dr. Toru Protocol is a supplement developed in collaboration with Dr. Toru Miyazaki based on his AIM research. It works by activating a cat’s naturally inactive AIM protein to support the removal of kidney waste and reduce inflammation. Greycoat Research continues to work closely with the Institute for AIM Medicine (IAM) to provide accessible, AIM-based kidney care for cats today.
Dr. Miyazaki’s AIM injection, currently in clinical trials in Japan, is designed to deliver active AIM protein directly into the bloodstream for more immediate waste clearance. It is not yet available for veterinary use and cannot be purchased or administered at this time.
What is the main ingredient of Dr. Toru Protocol?
Dr. Toru Protocol is primarily composed of an amino acid complex and coenzyme Q10. If your cat is already taking other supplements that contain amino acid, please contact us for a consultation so we can determine the optimal dose of Dr. Toru Protocol for your cat.
What is the recommended daily dose for my cat?
The recommended daily dose of Dr. Toru Protocol depends on your cat’s weight.
Under 3 kg* - 1 capsule a day
3 kg or over - 2 capsules a day
*Approx. 6.6 lbs
Please click Consultations Tab if you have any other questions!
Can I give Dr. Toru Protocol to my dog?
Yes, you can. Dr. Toru Protocol was designed to be compatible with dogs as well.
If your dog weighs under 4 kg, please administer 1 capsule a day.
If your dog weighs 4 kg or over, please administer 1 capsule in the morning and 1 capsule in the evening.
If your dog weighs over 8 kg, please contact us at Greycoat Research for a free consultation on your dog’s recommended daily dose.
Can I give my cat Dr. Toru Protocol and Intensive Protocol at the same time?
Yes, you can give your cat both Dr. Toru Protocol and Intensive Protocol at the same time. However, as Dr. Toru Protocol contains amino acids, we recommend giving it to your cat during or after meal/snack time. On the other hand, Intensive Protocol can be administered at any time.
What is the expiration date of Dr. Toru Protocol?
The expiration date for Dr. Toru Protocol is 2 years from its production.
