Test your product before buying

These are absolutely identical to the tests they hand out at universities and some counties where I live. The supplier address on the package is in Canada. For piece of mind, I've tested a handful of drugs that I bought from a pharmacy in Mexico and it is easy to use and seems precise. I suppose someone could fake these test strips and print a Canada address on them, but it seems unlikely to me that they would go to that much trouble. Of course, I'm not buying street drugs either.

Makes you feel better but remember no test is 100% accurate be safe out there and be sure to use the proper amount of water and powder to get highest accuracy

Don't want to die, always test your cocaine

These strips consistently have super light almost impossible looking test lines the are faint negative tests.

They're accurate as long as you follow the instructions.

I have a friend who, fighting depression started taking Percocets. She’d taken them before she says once in a while, but now she’s developed and addiction. She wants to kick her habit and I’m trying to get her to go seek treatment. But she wants to wean herself off. Which means taking more. I know someone who died of Percocets laced with fentanyl. I want her to be safe.So I tried getting this. They won’t ship to my address. City prohibition? Idk why. If it works and can save lives. So I had them shipped to a friend. Same county, but apparently they aren’t backwards.So she got more pills last night. Tested. Positive for fentanyl. Hmm. Scary. She’d already had one and says she’d had pills laced with fentanyl before and can usually taste it. She didn’t taste it. But it says positive.Let’s try it again. Positive again.Let’s try it on tap water as a test. Negative. Ok so it can show something other than positive.Let’s try just a Tylenol pill. Positive.One review said it seemed to test positive for any drug. And I can’t argue.Is this some anti drug group that developed a test to give positive results for any drug. So that everyone is scared to do drugs? Any kind? Even Tylenol?Beware of this product. It doesn’t do what it seems to say it will do.In the photo are the tests. From left to right: Percocet, Percocet, tap water, Tylenol.

Clearly this product is accurate with a positive reading!! I am so pleased with this product and am so happy to have purchased it! I had just finished interviewing potential tenant to rent one of my homes and they left a container with powder just sitting right in my bathroom counter! I couldn’t believe it at first. I knew right then that I couldn’t trust this person to be my tenant and although I’d decided to not move forward with their candidacy, I just had to test it! Sure enough.. positive for the worst thing that has hit the streets. So thankful to have access to these kits!
