How will methamphetamine at 5-20 mg , once a day, affect blood , urine , and stool results? I would like a detailed answer if there's anything to look out for, but I would also like to know if it would affect inflammatory markers in blood, or any liver enzymes in blood/urine/stool that would be significantly changed. I would also like to know if Cortisol would be affected. Please note that this question is not regarding drug testing, but rather asking how it might affect these tests on average, or if it would interfere with normal results.
