one of my friends came to me with this vile of "fad" (fast acting deca ) wich sapposedly is only traceable for 2 months after use rather then the 18 months of the usual deca . the stuff is called something like nandrolene thyproponate . anyone ever hear about this stuff ?? and is it any good. this guy is takin 200 or 400 mg ( not sure but its ether one of the 2 ) and he is gaining resonable strengh on it , hes a 320 pound lineman . ALSO is anavar traceable in pee tests or do u have to do a blood test to detect its presence.
