How often have you tested a pill and it has come out testing posititive for MDxx and once you have taken it, it did not feel like MDxx, meaning it was adultered but showed MDxx. Did it test differently and you weren't sure.
Never. (*knocks on wood*)
However, that does not mean that it is not possible. I may have just been lucky. Usually I can tell with the test if there could be something else in the pill
(a slow reaction is usually a good indicator). Other colors present/a mix (which is rare to be able to see, because usually a good amount of an MDxx substance will overpower any other reactions) is also another one.
From reading the other thread, I can tell that you only have the Mecke reagent. I would recommend the Marquis reagent best for a single-test purchase. It's far more reliable at detecting other substances, IMO. The Mecke reagent was originally developed to discriminate heroin from morphines. It should really only be used for confirmation of other tests (such as the Marquis or Mandelin). I would recommend that you purchase a Marquis reagent either from Dancesafe, or from EZ-Test. My personal opinion, if it's within your price range (don't worry, it isn't too expensive), get the EZ-Test Complete. It includes the Marquis, Mandelin, & Mecke, as well as the Simons, & Robadope.
All these tests can work together in a synergy on scrapings from a single pill to determine what adulterants are in it. The good thing about having multiple reagents, is that you can confirm exactly WHAT is in your pill, beyond the shadow of any reasonable doubt. However, there are certain substances that are present in pills that cannot be detected by the reagents, and the common one is the BZP/TFMPP combo. The other one is PMA (
EDIT: Mandelin & Simons can test for PMA, since it's a primary amine. Mandelin will turn green, then red, then brown. Simons will turn red, but this could also indicate MDA. Check out the link below for more information.).
I hope this helps.
