5-Pack

Fentanyl Test Kit

The Fentanyl Test Kit is your first line of defense against overdoses. Our test strips provide reliable and straightforward testing for the presence of fentanyl in drugs- a powerful synthetic opioid that is often secretly blended into substances and can be lethal in small doses.

Fentanyl can sneak into drugs like cocaine, heroin, meth, counterfeit prescription pills (oxycodone, Xanax and Adderrall), and ketamine. So wise up, suit up and test your stash.

99% accurate when used as directed

Results in 3 minutes

Reacts to over 100 different fentanyl analogs

Super sensitive detection limit of 15 ng/ml

Tested & approved by 3rd party labs

What's Inside

5 Test Strips

five fentanyl test strips in an overdrive test kit that help prevent overdoses, dangerous side effects and lethal doses of fentanyl

Each strip has a 15ng/mL detection threshold.

5 Water Pouches

five fentanyl water pouches in an overdrive test kit that help prevent overdoses, dangerous side effects and lethal doses of fentanyl

Each water pouch has 1mL of purified water, used to dilute substances for testing.

5 Mini Spoons

five mini spoons in an overdrive fentanyl test kit that help prevent overdoses, dangerous side effects and lethal doses of fentanyl

each mini spoon (10mg) ensures precise dosage of drugs in powder form.

How To use

Preparing Pills

a credit card crushing a drug pill that could contain fentanyl and distributing it in a clean plastic bag so that it can be tested with the overdrive fentanyl test kit

What does your substance look like?

Powder = Ready to scoop

Pill = Crush the pill and add the contents to a separate container and shake it well.

Ready to Scoop = Flour or table salt consistency

Crush More = Sea salt consistency

Preparing Powder

a side-by-side comparison of two bags, one with powder that is an appropriately fine consistency to test with overdrive test kits and 'fine to scoop', compared against a bag that is chunky and needs to be 'crushed more'

Once you have a flour or table salt consistency you’re good to go. Otherwise, crush more.

Step 1

an open water pouch from an overdrive fentanyl drug test kit in the hand of someone who is about to test for dangerous or lethal doses of fentanyl

Grab the water pouch, tear the top, and lightly compress the edges to hold it open.

Step 2

a side-by-side comparison of two overdrive mini spoons, one with the 'perfect' amount of powder that is level with the spoon, and another that is 'too much' and heaping over the spoon

Measure a level scoop of the substance into the mini spoon. Warning: Using too much or too little product will not yield accurate results.

Step 3

an overdrive fentanyl testing mini spoon distributes powder into a water pouch, and then the spoon is used to stir the powder inside the pouch

Add 1 scoop to the water pouch. Use mini spoon to stir well for 15 seconds.

Step 4

a visual instructional guide on how to use the overdrive fentanyl test strips to test for dangerous or lethal doses of fentanyl

Hold the water pouch open and upright.
Do NOT let it go until testing is over.
Dip the strip into the water pouch, up to the red arrows, for 15 seconds.
Do NOT let go of the strip.
Do NOT dip the strip past the water limit.

Step 5

an overdrive fentanyl test strip next to a clock with a 3 minute timer, indicating how long it will take to effectively test for dangerous or lethal doses of fentanyl

Place the strip on a dry and flat surface. Result window facing up. Wait 3 minutes.
Important: Do NOT read the test results before 3 minutes or after 10 minutes or results will not be accurate.

Step 6

a comparison chart revealing the test results for different types of overdrive fentanyl drug tests, helping prevent overdoses and dangerous side effects

After waiting 3 minutes, read the results:
One Red Line on Top:
POSITIVE.
Fentanyl detected.
Two Red Lines:
NEGATIVE.
Fentanyl not detected.
- If you see a second line after three minutes, no matter how faint, it is still a negative result.
No Red Lines or One Red Line on the Bottom:
INVALID.
- Restart test from the beginning.
After 10 minutes the test strip is invalid and should be discarded.

WARNING: OVERDRIVE FENTANYL TEST STRIPS ARE USED TO TEST SUBSTANCES FOR THE PRESENCE OF FENTANYL AT A CONCENTRATION OVER 15 ng/ml IN WATER. THEY ARE NOT INTENDED TO DETERMINE THE COMPOSITION, PURITY OR SAFETY OF ANY SUBSTANCE. THEY ARE NOT INTENDED TO DETECT ANY OTHER OPIOIDS. THIS TEST IS INTENDED FOR HARM REDUCTION PURPOSES. IT DOES NOT ENCOURAGE THE USE, SUPPLY OR PRODUCTION OF UNLAWFUL SUBSTANCES. DO NOT USE AFTER EXPIRATION DATE. TEST STRIPS MUST REMAIN IN POUCH UNTIL USE. EACH TEST STRIP IS INTENDED FOR SINGLE USE ONLY AND SHOULD BE DISCARDED AFTER USE. NOT FOR IN VITRO DIAGNOSTIC USE. STORE AT 4˚C TO 30˚C (39˚F TO 86˚F) SEALED. KEEP AWAY FROM DIRECT SUNLIGHT. FAILURE TO FOLLOW THE USER INSTRUCTIONS MAY RESULT IN AN INACCURATE TEST RESULT.

Play smart, Stay safe

Keep naloxone close by — at home, on you, everywhere.
Don't mix your substances. combining drugs like meth, coke, weed or opioids with alcohol it's asking for trouble. seriously, it can be deadly.
Don't trust a familiar source too much. just because your drugs came from the same person or place as before doesn't guarantee it's safe now. drugs vary from batch to batch, and your body might react differently each time.
Never use alone. make sure there are people around who know you've taken something, just in case they need to step in with naloxone or call for help.
The composition of the illicit drug supply is often inconsistent. This means that one part of your drug batch might not have fentanyl, while another part could have a lethal dose. This uneven distribution is sometimes called the "chocolate chip cookie effect," where the drug is like the cookie and the fentanyl spots are like the chocolate chips– if you test one part of the drug that does not have a fentanyl spot, it will come back negative, but the remaining part might contain a lethal dose of fentanyl. Even if you buy from the same person, the concentration and mixture of the drugs can change from one purchase to another. Best practice is to always test the entire drug.
Overdrive Fentanyl Test Strips are used to test substances for the presence of fentanyl at a concentration over 15 ng/ml in water. They are not intended to determine the composition, purity or safety of any substance. They are not intended to detect any other opioids.
*The Test Strip has 99% accuracy but failure to follow the user instructions may result in an inaccurate test result.
This test is intended for harm reduction purposes. It does not encourage the use, supply or production of unlawful substances.
Test strips must remain in pouch until use. Do not use after expiration date.
Each test strip is intended for single use only and should be discarded after use.
Not for in vitro diagnostic use.
Store at 4°C to 30°C (39°F to 86°F) sealed.
Keep away from direct sunlight.

If you can see a second red line on the bottom with your eyes, even a faint one, the line is there. This is a negative result for fentanyl at a concentration of 15 ng/mL from your substance + water mixture.
Yes, we designed it this way for ease of use STILL FINALIZING THIS COPY.
Once your substance is ready (AKA it's a flour or table salt consistency), find a water bottle cap and fill it with 5 mL clean/drinkable water (1 cap = 5mL).
Use the mini spoon to add 5 scoops to the bottle cap and stir for 15 seconds.
Dip the test strip into the water in the bottle cap up to the red arrows for 15 seconds. Do NOT dip the strip past the water limit.
Place the strip on a dry and flat surface. Result window facing up. Wait 3 minutes. Important: Do NOT read the test results before 3 minutes or after 10 minutes or results will not be accurate.
For detailed instructions, visit our 'how to' page.
If you get a positive result, first and foremost dispose of your substance and do not consume it. Then click here to anonymously report fentanyl in your substance. We partner with Citizen to keep you informed about local drug lacing threats.
You can dispose of your used strips by throwing them away in the trash.
