I have some faint memories of an 80s comedy with a nerdy guy working on some type of formula to make himself irresistable to women. I recall at one point in the film, he's stampeded by an herd of fat women at a laudromat...wouldn't be surprised if this isn't a very well known film I've just forgotten the title of...
Sounds like Love Potion No. 9 (http://en.wikipedia.org/wiki/Love_Potion_No._9_%28film%29), with Sandra Bullock before she was famous.

Thanks but that's not it. I'd never seen that before but I did kind of enjoy a little bit more than I expected. Anyways, the film I'm talking about was from the 1980s as I know I watched it before I finished high school.
Maybe BEACH FEVER (1987)?

Or, could it be Fast Food from 1989 with Jim Varney? http://www.imdb.com/title/tt0097335/
Those don't seem to fit...I also seem to recall a seqeunce in which the lead tackles a whorehouse full of women and in the end has to tackle a fat lady although I'm not entirely certain that is from the same film....anyways an 80s sex comedy romp and perhaps Canadian too....
I remember something like that, but it was a student that hide the potion in a hole on the wall...
i would like to know it too... may be it`s from the same movie.
I suspect it might just be The Party Animal (1985).
Yep, put this in Solved. It was indeed The Party Animal which I just confirmed for myself after watching some Youtube clips.
