Does anyone have experience with GS-441524?


My friend’s cat was diagnosed with feline infectious peritonitis (FIP) today and he asked me to do some research about it.

I have seen some conflicting information about it, namely one site will say “There is no treatment and it is universally fatal” and another site says “It’s actually curable, you just need to buy this non-FDA approved compound and administer it yourself.”

I’ve also seen its sourcing being described as “black market” which is quite confusing. Does this mean this stuff is illegal (in the US)? If it is legal, is there a good way to figure out if a supplier is legitimate?

If there is in fact a safe and viable cure to an otherwise fatal disease in cats, I find it mind boggling that it doesn’t appear to be readily available to veterinarians.

Yes! GS/Mutian/etc. saved our kitty! she was diagnosed with FIP and the emergency vet said we should put her down. Took her home to say goodbye and did some more research. A few Facebook groups and about 12 hours and we had a couple of vials.

The injections are horrible to administer and use a super large needle that really hurts the cats but it's worth it. We transitioned to pills after about a month when we saw that the meds were clearly working and she wasn't on the brink of death.

She's still with us today. Absolutely destroying our furniture.

such a shame GS can't be prescribed

Probably. It seems like something a veterinarian would know about.

This is a question of whom you trust more:

A. Random websites who have something to sell.

B. Random strangers spending spare moments of attention on a website about startups and software engineering.

C. Someone local to you who spent years in veterinary school and is now spending focused time in-person to care for a particular cat.
