I bought the BF&C ointment (it has a different name though) and the Black Ointment. I haven't seen any results with either. But I haven't been able to leave the Black Ointment on for very long. It smells really really bad, like burnt barbequed flesh. Definately not for vegans :)
I also bought the Jurassic Green powder. I don't see anything wrong with it, but I would have like better labelling, such as nutritional info.
