GS-441524 IS A BLAACK MARKET.
No matter which brand or no matter now or future, at present, it’s impossible to have the license.
GS-441524 is an antiviral drug which was developed by Gilead Sciences. It is the main metabolite of the antiviral prodrug remdesivir, which the latter is converted into inside the body.
GS-441524 is then phosphorylated to the active nucleotide triphosphate form.
GS-441524 has also been researched in its own right, as a treatment for feline infectious peritonitis (FIP), a lethal coronavirus disease which affects domestic cats.
Since FIP is usually fatal and there are no approved treatments available, GS-441524 has reportedly been sold on the black market and used by pet owners to treat affected cats, despite not having been officially approved for veterinary use.
