Hi guys, I was just wondering how long npp can show up on a blood test? I know Deca can show positive for up to a year or even longer, so I don't dare use it because I don't want to get booted of my TRT. I realize the difference between the 2 esters and how they get out of the body but not sure about the testing on Npp? Does it test positive long after discontinuation like Deca? Any info is greatly appreciated guys.
