I'll spare you the poison lecture, and tell you it's really not worth it, especially if that's you in your avy.

Anyway, I wouldn't run it for 3-4 weeks. Even at a low dose, you don't want to go for long periods on it.

And if your main concern is sweating, then you definitely don't want to run it.

I sweat my ass off, even on moderate doses of DNP.
