regarding the 7 day, i used a similar product, paid $120 OTD and i am 100% convinced it worked. I was skeptical, but i couldnt risk failing. So it was one of the measures i took. After doing the prog, i got a negative result from Phamatech's alleged and promised GC/MS. By the way, it cleans you out by giving you burning acid diarrhea of a type i had never seen before. They failed to mention that. And i had to stick to a STRICT diet. But i think it worked.
