An attention to detail and a good memory is really all there is to it. And my memory is pretty ordinary.
They are definitely from the same pressers - thats clearly evident; but that doesnt mean they contain MDMA from the same manufacturer. Plus there is the added variable of other potential ingredients, the actual dose (the biggest variable) and the fact that MDMA, even produced from the same manufacturer, is never exactly the same between batches. (we are not talking pharmaceutical companies here when it comes to the manufacturers)
The reports I have seen may indicate Pandas slightly better than the Sams - similar sounding effects though. As I've never had the former I cannot (and probably shouldnt) comment further.
Anyone on BL had Pink smilies? 8 x 4 or 5mm; flat both sides; pink with some whitish hue and a score. Good testing marquis and simons reactions.
There seems to be a few reports from Pillreports but several batches with different looking logos and various shades of pink.
