What was found in tested Bowser pills?
Bowser pill reports can differ in colour, contents and strength. Recorded samples are most often brown (30%), yellow (30%) and green (10%). Of the 11 samples, 9 had a measured MDMA content: from 77 mg to 222 mg, with half coming in above 176 mg and one in ten above 222 mg.
Here you can compare independent laboratory results for 11 photographed samples tested between 2022-03-15 and 2026-02-09 and listed in source records under names such as: Bowser. The photos and reports can help you find visually similar results, but they do not prove that an untested pill comes from the same batch.
Appearance cannot identify a tablet, which is why every sample here was tested rather than judged by eye.
The Bowser stamp is used on the illegal market for tablets of different composition. The name, the press and the colour are not reliable marks of a particular batch. Even tablets bought in the same place and looking the same can come from different production runs.
Laboratory results show wide differences in dose, purity and adulterants. A tablet sold as ecstasy can carry an unexpectedly high MDMA dose, other stimulants, or substances that were never declared. That is what raises the risk of overheating, circulatory problems, serotonin syndrome and overdose, and it is exactly what a test answers before anyone takes anything.
A reagent test tells you which group of substances a sample belongs to. How much of it is in the tablet is what a purity or quantity test answers, and a full laboratory analysis names every component. Test a small portion, use more than one reagent, and compare the result with recent laboratory alerts.
