Large doses of NSAID

At what doses do large quantities of NSAIDS start to effect athletic performance?

2400 mg/day is considered to be the top therapeutic level.

K. Murtha, ATC

Which kind of NSAIDS is that exactly?
I have values on some medications that it somewhat different, up to 150 mg on some for an exampel.

Sorry! I should have been more specific . Rx Ibuprofen 800mg x 3

Vioxx single dose 12.5 mg. You can take a max of 50 mg
