I know there are MD**/amphetamine pills with the Fox racing logo, but since they are not those...
It is extremely rare that a white pill sold in Québec is anything other than methamphetamine or some sort of cathinone.
Most likely meth though.
If you are new to speed, take a quarter of a pill to start. Some can be very strong, like the old On* and the ICE rectangles.
Make sure to keep hydrated and to stretch now and then.
