Substitution question

I don't have any non-lubricated condoms lying around for subbing...
would lubricated spermicidal ones work if i washed it out well?

I've never been a fan of the condom method. I like bottles as they are less prone to accidents. 2 ounces at least, 3 is plenty.

then how would i go about warming the piss? doesn't have to be exact, it's only a walgreens take home test

Its your friend. ;)

Sounds like you can dilute yourself to the max being a walgreens take home tests. Does not sound like they will be checking for creatine or specific gravity levels. So no need to worry about a negative dilute.

Put 2 ounces in the microwave and nuke it for 10 seconds. As long as there's no temp strip being used it'll get you in the ballpark.
