From the product description:

"Once the 5 Day kit is completed, your body will return to a more natural and healthy toxin free balance."
If you take such claims at face value, then I have a planet in another solar system that is for sale.

Detox products are a scam to capitalize on the so-called "war on drugs" by preying upon the uninformed and credulous, and taking their cash.
When they work at all, they work by diluting. That means they "work" because of the water that youre required by the product instructions to drink with them. All what youre doing is diluting the THCA concentration that is present in your bladder to where the sample registers a negative on the drug screen. The dilution phenomena however, is only temporary - once the fluids ingested had all been urinated out, a 'dirty' donor would resume testing positive for THC.

There is no product that can permanently rid the body of THC, as the sales pitches would like the consumer to believe. Only time and fat-burning exercise can rid the body of THC.
