soap in urine test

Only Ivory brand. None of the others work.

Soap denatures (i.e., degrades and destroys) proteins like EPO, and probably also changes small molecules like steroids, etc. That's how it cleans things.

So, chemically, sounds like it'd work.

But, watch out for the pH. Soap is basic, it should change the pH of your urine. I thought that they checked the pH right on the spot, to see if it was normal, or if you'd added something? Please correct me if I'm wrong.

BTW, I read in a scientific journal that an acidic pH destroys injected EPO in the urine "within seconds". If you don't mind having acidic urine, that sounds good. Try vinegar (acetic acid) or lemon juice (citric acid), or pure cranberry juice. That's acidic enough to kill the bacteria that cause urinary tract infections just by drinking it; you might not even have to mix it with the urine, just drink a lot of it. Maybe all these would be acidic enough.

If you can manage to puke into the urine🙂, your stomach is full of hydrochloric acid (pH 3), and that'd do it for sure.🙂🙂

Interesting re the Ivory! Can't think of any reason for that, except that Ivory is the only one that advertises itself as "100% Pure". I don't know why that'd help.
