Deige,

I am talking about post #3 on that link. It says:



"Canadian version is no good for Metrolab tests.

I was reading about the issues with the testing facilities in the pacific northwest (Metrolab) and decided to give the Canadian version a shot. Took my test on the 8th and my boss informed me today I failed due to synthetic.

So, if you live in (or near) the pacific northwest i'd steer clear of synthetic substitution and stick with the real deal. Save yourself a headache. "



That is what I would like your opinion on
