In the past month checkit! a number of substances of health concern were tested. Among other things, four samples brought for analysis as "speed" were again found to contain the as yet unexplored substance 4-Methylamphetamine identified. As several deaths have already occurred in connection with the consumption of 4-MA, we strongly advise against its use!

Under the following link, all samples that have been collected from 1 September to date at checkit! analysed and classified as high-dose, unexpected or of particular health concern.
