Thanks for your replies everyone.
The pills we got are White Euros: white with brown speckles, a 'C' with a '=' through the middle (YES, Pilgrim, the Quake symbol!!), well pressed, stamped and scored. (ie, they look quality). We paid $45 each for 20 (!!!) and are kicking ourselves for buying that many without testing (stupid stupid stupid!)
We took about 5 each over about 12 hours and they had absolutely NO EFFECT on me!! My partner started rushing on the first half, but after 5 minutes that stopped. Now, maybe it could be cos we've eaten too many over the last couple of years and they're no longer having an effect on us (mind you, A1's did the trick a month ago) OR these pills are *CRAP*.
We haven't tested them yet, will be getting a kit tonight hopefully, so stay tuned for the results...
