was hesitant to test them because the Marquis testing kit was pretty old, easily over a year old. Anyway these pumpkins tested to a dark muddy purple in about 10 seconds. Other pills, most recently the blue guns took 10 seconds with that same old test kit. And according to ecstasydata.org those are 20:1 mdma to caffeine, (albeit low dosage, my guess would be ~60-70 mg mdma on the guns)
So the long delay in turning purple/black with the pumpkins may be because of the old test kit as well.
Anyway did get two first hand reports on this same batch of pumpkins from two other experienced ppl. One said that they were some of the best pills he ever had with no hangover. The other person, whom I personally trust said "they are awesome, much better than the blue guns.. a lot better".
Sounds encouraging.
