Last time I saw pink stars in the NE, there was a mixed batch going around ... about half of them had a pretty defined ridge around the outline on one side, and the other half in the batch didn't. Both were guinea-pigged and the ones with the outline were found to be bunk (no definite word on whether they were pipes or blanks, but they definitely weren't MDMA). The ones without the ridge, which seem to be the same as what that picture shows, were active, but weaker than stars have gotten a reputation in this area for being (the beige ones were the best so far, but some really nice pink ones have been seen too, and even the good ones in this batch weren't up to the same standard). Unfortunately nobody who had access to this batch that I know of had a test kit, so this is anecdotal more than anything else.
A new batch has apparently showed up, however, that is of significant quality (perhaps comparable to the beige stars, which have the best reputation that I know of). They're bright robin's-egg blue, and aside from that have the same press as any of the others (and no outline ridge).
