7 day cleanser, $100 if the guy at store swore it would work would your believe him?

I went to a local store and checked on some products most of them you take 1 hr before and they mask the thc but one product is a 7 day cleanser I was told would clean your body of everything in 7 days and it wouldn't be detected because it all natural.

Does that sound correct to anyone and has anyone used something like that. Also can I trust it will work? I failed a test at home tonight with flying colors and I'm screwed...

Quick Fix

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.

the product name is purified and completely clean I just bought it tonight, for seven days 3 times aday you have to take 2 pills w/24oz water. It recommends you drink 8-10 glasses of water on top of that and stick to a low fat diet.

Ingredients are"alfalfa (detoxifier) red clover (blood purifier) burdock (blood purifier) dandelion (liver cleanser)

I really need to pass this text sometime next wk.

anyone heard of this one or if the ingredients work?
thank you
