Got my tests in 2 days, and was able to confirm my MDMA was indeed MDMA in time for the weekend. The tests worked great.
Are there cheaper Fentanyl Test Strips elsewhere?
Dosetest is the cheapest provider, and it’s not by chance. We are committed to offering the most accessible tests, both by providing subsidized tests to charities and mutual aid orgs, and by offering you the lowest price on the market.
That’s why we offer our price match guarantee: if you (somehow) find a better deal elsewhere, just let us know. We won’t just drop our prices for you, we’ll reduce them for everyone.
How do I use the test strips?
We recommend you utilize our app, which runs you through optimal testing to best avoid false positives (Possible with MDMA, Methamphetamine if you do not dilute your sample according to instructions properly).
What exactly are Fentanyl Test Strips?
If there’s no fentanyl the control particles will bind to the testing line, causing it to become visible, but if there is then the fentanyl will bind instead and the line won’t appear.
When will my order arrive?
Is the package discreet?
Can I get help when testing?
Can I purchase a larger amount than 100 units?
Absolutely! Our Fentanyl Test Strips are packaged in 100 units per bag, that’s why we have that as the maximum bundle size on the store. To purchase more than 100 units you can just multiple the 100 units bundle as many times as you need at checkout.
Where can I see the third party testing?
Our Third Party testing can be seen here.
Can Fentanyl Test Strips produce false positives?
False positives occur to multiple substances (Like MDMA) with all Fentanyl Test Strips on the market, including ours – Any claims otherwise are false.
Some false positives are avoidable (e.g. MDMA & Methamphetamine) by diluting your sample according to instructions, and others that are not avoidable, like MT-45, a rare synthetic opioid.
We recommend using our app as it guides you through the correct dilution methods depending on what substance you have.
