Fentanyl Test Strip — Single Strip, Letter Mail (Canada & USA)
Description
One fentanyl test strip, mailed in a plain envelope.
Fentanyl and its analogues turn up in powders that are sold as something else, and a dose that looks the same as the last one can be several times stronger. A strip is cheap and takes a minute.
What it does: detects fentanyl and fentanyl analogues in a dissolved sample at a cutoff of 200 ng/mL. Control line plus test line is negative. Control line alone is positive. No control line means the strip failed - do not read it as a result.
How to use it: bring the strip and the sample to room temperature. Dissolve 5-10 mg of the sample in 5 ml of water and stir. Dip the strip to the wavy lines, not past the solid line, for 10-15 seconds. Lay it flat and read it before 10 minutes.
A positive means fentanyl may be present, not how much, and a negative does not clear a sample - analogues and uneven mixing can both slip past a strip. Presumptive test only, not a lab analysis.
HOW IT ARRIVES
One strip, sealed, with the instruction card, in a plain envelope. Letter mail, so there is no tracking number and no signature - if you need tracking, message me before you order and I will quote the tracked rate instead.
Ships from Canada. Canada and the United States. Letter mail is usually 3 to 7 business days in Canada and 5 to 10 to the US, but it is not guaranteed and it is not tracked. Posting happens within 2 business days of cleared payment.
Buying more than one? Message me and I will put a multi-strip listing together, or see my 10 and 100 packs if you want the whole box.
Payment: XMR direct. Message me before ordering if anything is unclear.
