The kit is about 1 yr old, but I have taken it around to unsavory places(porta potties come to mind) for testing so anything is possible. I am normally really careful to not get any contamination, but I may have ended up with some from the packing sawdust type stuff the vials shipped in. Looks like a new kit may be in my future...
The 2nd reaction (Mecke) looks just like all the previous good ones that I have tested which is why I was concerned the 1st (Marquis) didn't turn as dark as it normally does. But hearing one of you say Marquis looks like MDXX gives me some comfort LOL. I will probably end up taking these in about 2 weeks which is the true test I guess. I don't have a problem with MDXX+ some Speed too much as long as they aren't complete meth bombs. It is really pipes and DXM that I want to avoid.
I normally never use the knife to swirl the stuff around, but got frustrated since it didn't look like too much of a reaction in the video so figured I would try it to see. I also normally start with the scapings first, then the reagent, but figured for the video it might be clearer in reverse.
Thanks for your help and anyone else feel free to chime in with your thoughts.
