I have heard of some collectors trying to get more than 2 ounces from people before but this is rare, like 1 out of 200 and against procedure/guidelines. Most urine tests now are done with a split sample, one vial containing 30 ccs and another vial containing 15 ccs. A lot of collectors will just put 30 ccs in both vials. Any collector asking for more than this is full of shit and just messing with you because they know substitution goes on. I would rather do 2 ounces and be comfortable than a 3 ounce bottle pushing on the back of my scrotum.
FakeBoobsRule Reviewed by FakeBoobsRule on . So I have a pre-employment test 640SN SAP 5-50 GC/MS... So I have this pre-employement test tomorrow and I've spent all weekend working on detoxing myself. Thats plan B, Plan A is to use a substituion and make sure that the temp is right around 95 degrees. My question for you guys is if any of you know about the 640SN SAP 5-50 GC/MS test....is this a standard test, or a more accurate one? The substitution i'm using is from someone who doesnt smoke weed at all. BUT he did do some speed on 10/31, I wont be picking up the substitution till 1 hour Rating: 5
