you can get fentanyl test strips from a number of different places for about a buck a piece. im not sure about amazon but im pretty sure you can get em there. nevermind, just checked amazon, you can get a 5 pack of test strips shipped prime for 6.50. sure they could ship those pretty fast if you wanted them quickly, i personally order mine from endoverdose.net. $1 a piece for their strips and they are an organization i feel very happy to support. they will also ship out narcan if you need some. if you dont have any at home, you need some. not implying anything, just to be clear, i just think anyone who does any opioids at all ought to have a dose of narcan in the medicine cabinet. but yeah, it will take a couple days from endoverdose but again, i feel great sending them my money because i think they do good and important work. if you have a harm reduction service there locally where you live, you may be able to grab some test strips there, likely for free. and of course there always plenty of options for entire test kits, that will cover 1 to...all the drugs. marquis tests are great to have around. i like testkitplus.com, they have all sorts of test kits and they offer an essentials kit for about $50. those come in handy. also, unless i was hallucinating when i was shopping around there on their site a couple of weeks ago, if you hang around there on the site poking around long enough, they will eventually offer you a pretty generous break on the price. again, im all but positive thats for real, but i cant say for certain what exactly it was that i did or how long i was shopping around before they offered me that discount. ill post it up if i can figure it out. or if i figure out that i was in fact tripping and just made that all up. so you got some options.
