What are peoples views on the following research?
"A 2004 article in the The Wall Street Journal noted that a study published in Nature Medicine had found that GW501516 increased polyps in specially-bred mice,[3][28] but GSK said that they had not identified any safety problems with the compound and would continue to develop it.[14]
In 2013 New Scientist reported that "tests on rats showed that at all doses, the drug rapidly causes cancers in a multitude of organs, including the liver, bladder, stomach, skin, thyroid, tongue, testes, ovaries and womb."[4] In 2013 WADA took the rare step of warning potential users of the compound of the possible health risks. They stated "clinical approval has not, and will not be given for this substance".[2][24]"
