Hello from Greycoat Research,

Many cat parents caring for cats with CKD have heard about AIM research and the future possibility of AIM-based pharmaceutical treatments.

Because Greycoat Dr. Toru was developed with Dr. Toru Miyazaki, we sometimes receive an important question:

Is this AIM supplement the same as the AIM injectable?

The answer is simple:

No. Greycoat Dr. Toru is not the AIM injectable.
It is not a drug, and it does not directly supply AIM protein into the body.

The AIM Injectable: A Pharmaceutical Approach

The AIM injectable being developed by Dr. Toru Miyazaki is a pharmaceutical approach.

Its purpose is to deliver AIM protein directly into the body.

This AIM-based injectable has been progressing toward potential commercialization in Japan, with a possible launch timeline around 2027, depending on regulatory approval.

This is very different from a daily nutritional supplement.

Greycoat Dr. Toru: A Nutritional Approach

Greycoat Dr. Toru is different.

It is a daily nutritional formula designed around AIM-IgM biology in cats.

In cats, AIM has been reported to bind very strongly to IgM.
Because of this strong binding, AIM may not dissociate efficiently when the body needs it.

This is one of the key scientific ideas behind Greycoat Dr. Toru.

Rather than supplying AIM from outside the body, Greycoat Dr. Toru is designed to support the internal environment in which a cat’s own AIM may be more functionally available.

In simple terms:

• AIM injectable:
  Directly provides AIM protein into the body.
• Greycoat Dr. Toru:
  Supports the AIM-related biological environment already inside the cat’s body.

The AIM-IgM Biology Behind the Formula

AIM normally circulates in the blood while bound to IgM, a large immune protein that helps carry and stabilize AIM.

In cats, AIM has been reported to bind especially strongly to IgM.
Because of this strong binding, AIM may not separate efficiently from IgM when the body needs it.

This AIM-IgM binding is supported by strong biological interactions, including disulfide bond-related structure and charge-based interaction.

Greycoat Dr. Toru was designed with this biology in mind.

Its amino acid and peptide-based formulation was developed to support a biochemical environment related to AIM-IgM balance, rather than to directly supply AIM from outside the body.

The goal is not to replace AIM therapy.
The goal is to support the internal environment in which the cat’s own AIM may be more functionally utilized.

Why This Difference Matters

This distinction is important.

Greycoat Dr. Toru should not be understood as a replacement for a future AIM injectable treatment.

It is also not a product that directly adds AIM to the body.

Instead, it is designed as a daily kidney care supplement that supports the body’s natural AIM-related environment, alongside broader kidney care routines.

That is why we describe Greycoat Dr. Toru as:

AIM-based daily kidney support for cats.

Role in a Broader Kidney Care Routine

That said, we do not position Greycoat Dr. Toru as a replacement for veterinary-directed kidney care, renal diets, phosphate binders, or veterinary-prescribed treatments.

It is intended to be used as part of a broader kidney care routine, depending on each cat’s condition and veterinary guidance.

For cats with CKD, daily support often works best when nutrition, veterinary monitoring, renal diet, hydration, and supportive routines are considered together.

Greycoat Dr. Toru was created to serve as one part of that larger routine.

A Daily Foundation for Cat CKD Care

For cat parents, the practical meaning is simple.

Greycoat Dr. Toru is not a one-time medical treatment.
It is not an injection.
It is not an AIM-based pharmaceutical therapy.

It is a daily nutritional supplement designed to support cats through consistent kidney care routines.

For cats with CKD, daily support matters.
And Greycoat Dr. Toru was created to serve as one part of that daily foundation.

For cat parents caring for cats with CKD, we hope this information helps you better understand the difference between an AIM supplement and an AIM injectable.

With care,
Greycoat Research
