I am slightly confused about the different testing kits available and their relative accuracy and ease of interpretation. For testing substances such as Mephedrone, MDAI and 6-APB, what would you recommend?
^Buy a complete kit - regardless of the supplier the solutions are the same thing
If you want to test for the full range you will need the following
Marquis
Mecke
Mandelin
Simons
Robadope
I will send you a PM with the name of a supplier and some further information - I would advise against buying from EZtest at the moment as I have just heard that some orders are still not delivered that were ordered in June.
