CureFIP™ GS-441524 Injectable 30mg/ml
The Standard FIP Treatment Concentration — CureFIP™'s Most Widely Used Injectable
CureFIP™ GS-441524 30mg/ml is the most widely used formulation in our injectable range. Optimised for the standard FIP treatment protocol in adult cats weighing 2.5 to 5 kg, it covers all FIP types without neurological involvement: wet form, dry form, and ocular form.
Why 30mg/ml Is the Standard
FIP treatment dosing is determined by mg of GS-441524 per kg body weight. The 30mg/ml format simultaneously satisfies three clinical requirements across the most common adult cat weight range (2.5–5 kg):
- Injection volume remains within a clinically practical range
- Does not require excessive volumes as occurs with the 20mg/ml format
- Does not produce volumes so small that accurate measurement becomes difficult as occurs with the 40mg/ml format
This concentration delivers the most practical balance of dosing accuracy, administration ease, and therapeutic efficacy for the typical adult cat FIP case.
Indicated Cases
- Adult cats weighing 2.5–5 kg
- FIP without neurological symptoms (wet form, dry form, ocular form)
- First-line treatment following new FIP diagnosis
- Cases selecting GS-441524 monotherapy

Reviews
Just started the FIP injections, and my cat is already showing signs of improvement—more active and alert. It’s only been a few days, but I’m hopeful and encouraged by the progress so far!
My cat was sick, and there were no signs of her responding to any medication. This medication was a godsend .. 45 days through the treatment, she is back to her playful self and regained all the strength and weight loss during the initial two weeks. Would highly recommend this !!
عندي قط يعاني من النوع الجاف مع خلل في الاعصاب بسبب الفايروس والحمدلله بعد شهر من العلاج اختفت اعراض خلل الاعصاب ونتائج تحليل الدم كانت ممتازه وهو حاليا في المرحلة الثانيه وأصبح يعتمد على الكبسولات
Very effective treatment. It treated my cat from a disease after I lost hope of his recovery, and I noticed an improvement in his health after 4 days of using the medicine.
I am very happy to say we reached day 50 on the treatment and pretty much all of the symptoms that my cat had disappeared.
