Help needed to interpret test results.

[j0n]

Yesterday I bought a batch of round white (slight speckled pills)with embossed Superman logo + score on reverse . When I tested with EZ-Test the agent turned purple / black after about 10 seconds then strangely after an hour turned green / yellow. What should I make of this yellow colour?
Thanks

Taken from the Pill testing FAQ:

How long does the reagent take to react?
You should observe the initial reaction, most pills will react in the first 10 seconds and after a minute the reaction should have taken place, after a few minutes it is likely that the reaction will go green this is normal and does not mean you have 2cb.
