Fuck me! and you wanna pass a drugs test.
Nandrolone will be the worst to hide. There are blockers, but they are usually tested for now. Normally people stick to shorter acting stuff if they know they are gonna get tested. Then they come off, drink loads of water, lemon juice and 99% of the time pass. However my advice to you is get somebody elses blood. You will never pass a test after all that - especially the long acting stuff.
