Thalidomide was animal tested before release according to the references I can find – but not as thourghouly as it would be now.
Bingo TJ speaking crap again.
Thalidomide is good and work well, but only the R enantiomer. The S is responsible for all the problems.
Due to greed and capitalism, when the Thalidomide went into production, no separation of the enantiomers was done hence badly formed babies. That is the most know example in any chemistry classes. Please TJ check your sources…
