I won't tell you how long speed is going to stay in the system because this site is dedictated to marijuana. If you can find another donor, you should. Urine is good for about 8-12 hours at room temperature, 2 weeks in the refrigerator, 1 year in the freezer.

640SN SAP 5-50 GC/MS test is a 5 panel substance of abuse test, probably opiates, THC, cocaine, PCP, and amphetamines so if the donor has been taking speed it could be detected. This test will also be using a 50 ng/ml cutoff on THC and two types of tests may be run on the sample. If the sample fails the immunoassay (the first test) it will be confirmed by gas chromatography/mass spectrometry. If you want more info on the test, list which lab and not just the numbers.
