Dilute 10 mg of powder into a teaspoon of water (5 ml), then follow the instructions as you would for our fentanyl test strips.

Use one teaspoon of water for every 10 mg of powder. This is 2 mg/mL.

2 mg/mL is the equivalent of one level micro scoop into one plastic bottle cap of water.
Many drugs, like MDA and MDMA, are in the amphetamine class and can produce positive test results with these strips. For this reason, you should only use amphetamine strips to test non-amphetamine drugs (like cocaine) for the presence of unwanted amphetamines.
