Have you ever run in to complications where you get an order, then reagent test it, it doesnt pass the test, you then let the vendor know, and they then claim their product is legit... so your test must be wrong.
I am currently dealing with this on a Ket order. Weird thing is, I've ordered from this vendor in the past and their K always tested positive. But this last time, the test shows the substance isnt K, and instead looks to be MXE or 2'-Oxo-PCE. It use the mandelin test, which normally turns orange with K, but this time it turned green. The substance also doesn't smell like normal K.
I brought this to the vendors attention, and they are just denying the test is accurate.
I'm not really sure how to go forward. I mean, if the vendor wont budge and refuses to believe me, I guess just take the hit and don't order from the vendor again.
meh...
Edit: The reagent test I have is not expired. I actually just got a new one 2 weeks ago. I still have some of the K from previous orders from this vendor. With the current reagent I just got, I tested one of the older batches again just to make sure its working, and the old K sure enough turned the right color, orange. The new stuff, turned green.
How old is your test kit? Could be expired.
I highly doubt it is MXE, in fact I am certain. There is a gap in the market for MXE so the vendor would be idiotic to advertise it as Ketamine.
