I took vyvanse 10 days ago im healthy fast metabolism am i good? will show in my urine? it was 20mg?

Should not be : Most references suggest such a dose would leave your system in 8 hrs on average with a possibility depending on metabolism/urine alkalinity of up to 31 hours. I think 10 days is enough time for no trace to remain.

No: Based on a 12-hour half-life for dextroamphetamine, one would expect the drug to be eliminated from the body within 2–3 days. For general purposes, it can be estimated that it takes about 5.5 half-lives of a particular drug for it to be eliminated from the body.
