My school does random drug tests for all students . I'm a senior power lifter with college offers and need to step up my game iv started dianabol and don't say I shouldn't take it Ik but I am anyways so don't even comment about that . How long does it stay in system after use stops .. And will a highschool even test for it

Some do and some don't that is usually a state or district policy.

I doubt it man. Make sure you take liver saver with that, you don't want the long term effects outweighing the short term.

Yes

If they do random drug testing, you can be sure that they will. Oh, and one more thing, NCAA is going to bounce your sorry *** out if they find out you are on the "juice."

***Just a comment for you. If you take steroids, your penis will get smaller.
