FipX™ delivers pure EIDD-1931, the active antiviral metabolite of molnupiravir, in a formulation designed exclusively for feline physiology. By using EIDD-1931 directly—rather than modifying human molnupiravir capsules—FipX™ provides a more precise, consistent, and veterinary-appropriate approach to FIP care.
Purpose-Built Feline Formulation
Each FipX™ capsule contains 15 mg of EIDD-1931, equivalent in activity to approximately 66 mg of molnupiravir (EIDD-2801).
This formulation is optimized for:
Feline metabolic rate
Gastrointestinal absorption profile
Reliable dose–response performance
The result is accurate, predictable antiviral activity with reduced variability compared to human-intended products.
Proven Antiviral Potency
Published research demonstrates that:
EIDD-1931 exhibits up to 10× greater in-vitro antiviral potency compared with molnupiravir (EIDD-2801).
EIDD-1931 demonstrates 7.3× higher potency than GS-441524 under similar test conditions.
This potency advantage enables therapeutic efficacy at lower milligram doses, supporting improved tolerability and rapid clinical response.

Reviews
I have 5 cats under medication for FIP and all have shown improvement. Just had to keep them under confinement and strict monitoring. Still a long way to go but hoping for the best.
Sobrang effective po ng product. Almost 30Percent na lng po ang chance ng alaga ko ... Dinala ko sa vet ang unti unti nakarecover xa .after 15days ng treatment nakarecover na po xa .
After a month, we go from GS vials to EIDD (oral medications). In just a few weeks, my cat regains her vigor and voluntarily eats and drinks, demonstrating how GS has changed our lives. Our veterinarian certifies that we can switch to oral medications because of her improvement. I am certain that she is completely recovered as of right now. We have a few days left to finish her EIDD oral medications before we can go back to the vet for more testing. We are currently on day 60 of this adventure.
