I personally think the marquis is still the best single bottle option - if you dont get a quick, strong reaction then simply dont take the pill. QUOTE]
I think that's the best solution. I'm gonna get a new kit since mine ran out. I would suggest that if a pill passes all tests and you're still suspicious of pipes to do a taste test. I might take some heat on here for suggesting it, but it has worked really well for me.
Just put one pill in your mouth and suck on it. If you know the taste of mdma, this should be a no brainer. If not, then next time you get a good pill, remember the taste. Pipes can be tasted even in pipe/mdxx combo pills.
For me, it's very acidic (like toucing a battery to your tongue) and makes my tongue start to go numb if I leave it on there too long. It's almost worth getting a hold of a pipe pill (shouldn't be hard nowadays) to taste so you know the taste. I can tell imediately if there's any pipe in a pill now just by sucking on it for 10 or 20 secs. It's saved me a lot of money. MDMA has a very different recognizable bitter as hell taste.
Anyway, that's my suggestion until someone makes a killing off coming up with a pipe testing kit. Also, it's funny seeing the dealers' reactions to me putting a pill in my mouth and sucking on it and then telling them they don't know what they're selling or the pills are crap or whatever.
