This is the drug that was abandoned in testing because it caused cancer to develop in several organs (liver, stomach,, thyroid, tongue, skin, bladder, testes, womb and ovaries) by all test subjects.
I believe it is the only drug that after WADA banned it, they actually did a press release to warn people against using it because it is so dangerous. They haven't done this for any steroid, fat burner or stimulant before.
Just something to take into consideration whether the doses we're higher in the test subjects than you plan to run or not. Is the risk, no matter how great of cancer worth any potential benefit? The patent holding company is not pursuing human tests because the animal tests were so conclusively linked to cause cancer.
