One of my room-mates in university was using this product, he showed me and my other roomies the warning pamphlet which contained a phrase that stands as the most disturbingly worded warning I have ever seen in a commercial product -

"If you are pregnant, and are considering taking this product, your doctor has a line drawing you should request to see."

No elaboration in the pamphlet, but I assume this was with regards to the birth defects. Kids, just say no.
