New and need help for upcoming test

Whats up guys i just signed up for these forums because i been doing alot of research online about beating the test and it seems like this forum has the most educated people on the situation. I have a test sometime in the next week or two(dont know exactly) and i smoke about 2 grams a day so there is no shot at passing if i abstain. After doing much reading i think the best route is the sub club. My question is if i can get clean urine from a friend is it more or less reliable than quickfix. I know the person is clean so thats not part of the equation. I am only reluctant to use qf because i am paranoid and think they can test for synthetics. I would really appreciate if people who actually know what they are talking about not just someone who heard from a friends friend that it worked for him once.
