Brief Answer:
may cause false positive

Detailed Answer:
HI, thanks for using healthcare magic

Most routine drug tests would not have it included on the drug panel which is to be assessed so it may not be detected directly. (In sports , the drug panel may be expanded to include it).

Despite the fact that it may not be detected directly, it can sometimes result in a false positive result for amphetamines/methamphetamines.

The half life of synephrine is approximately 2 hours. The half life of a drug is the time it takes for the amount of drug in the system to decrease by half.
It takes approximately 3 to 4 half lives for a drug to be completely eliminated.

This means that it would take 6 to 8 hours for most of it to eliminated though small amounts may remain.

I hope this helps, feel free to ask any other questions

Brief Answer:
based on half life

Detailed Answer:
HI

Based on the half life information seen. This was based on one medical study in which the half life was found to be approximately 2 hours. Different manufactures may vary the chemical slightly so it may not be exactly the same as in this study but should be approximately in the same time zone.

13 dimethyl is also used in dietary supplements. The half life is approximately 9 hours, this means an elimination time of 27 to 36 hours.
It can also cause false positives for amphetamines/metamphetamines

Brief Answer:
would be fine

Detailed Answer:
Hi

Yes, 2 days should be fine. Since there is slight variation in products, if it is possible to discontinue for longer that would be even better but if only 2 days that would be sufficient based on known metabolism of agents.

It would still be better to let the persons conducting the tests know of any supplements, over the counter medications and prescription medications that you are using.
