So I had a substance x tested a while ago with EC. When submitting x I selected the substance I believed it was. EC confirmed it was x and had no impurities.
Being paranoid, I resubmitted x but rather as an unknown substance (and with a new psuedonym). EC came back and said that x was not an activate substance.
Does this raise doubts about EC?
it might if you had proof, like the tests.
