I have some samples of Methylone and Mephedrone that I'd like verified beyond my Marquis reagent.
My understanding is that EC uses TLC and ED uses GC/MS (not that I really know the difference), and that ED is not permitted by the DEA to provide quantitative results.
I'm not looking for quantitative results, just to verify that these powder/crystal samples are the correct compounds. Is there any reason for me to use one over the other. I'm leaning towards Ecstacydata because I'm more familiar with them and I am located in the US.
EC is cheaper costing 50 euros compared to $100 for powder samples at ED.
