Correct me if I'm wrong, but a positive result for THC won't affect the valitality strips, right?
Right. A person can still test positive for THC while passing all of the validity checks.


Does anyone know if 4 pills of 7,500mg of creatine supplement a day (total of 30,000mg) is enough to NOT get a dilute on a test?
The validity test strips would tell you the best (most accurate) story on that issue.

Be sure you dont go overboard on the creatine loading though - unless you like to spend long periods sitting on the crapper seat.
