Never really cared for them myself. Like others have said, why pay $50 for a pro-hormone that may or may not work when I know a bottle of test will work? It's not as if pro-hormones are regulated any more or less than anything you can get from a sponsor with a halfway decent rep. The only thing the FDA does is make sure it's not going to kill the first 20 people who take it. They don't intervene until after something has been reported dangerous, not if it doesn't work.

To be honest, all a pro-hormone has proved to me to be is a validation of questionable marketing practices. Anything that tells you your bench will increase 610% in 4 weeks just go ahead and avoid.
