i read in ironman that some real good chemists were looking through old pharmacological papers and finding these steroids that no one ever produced. one was norbolethone or some shit, its anabolic activity was 20 times highere than its androgenic. it was also very toxic to animals. part of the reason it was never on the market. well someone kicked across it, added it to the screen and found it in someone piss. im sure ppl have found the test times for various drugs, but id say more often than not they have something the mainstream medical establishment has never heard of, and therefor cant test.
