Mar 17 2021: Submitter indicates they think this sample is MPT. We have spent a lot of time searching unsuccessfully for an MPT standard. According to Alexander Shulgin's Mass Spectrums that he gave us in 2005 for samples he had synthesized himself, MiPT and MPT look *very* similar via GC/MS. We are seeing only a single chemical in this sample and it matches the MiPT (N-Methyl-N-isopropyltryptamine) standard from CaymanChem. But without a proper MPT standard to compare to, all we can say is that we can't rule out that this might instead be MPT (N-Methyl-N-propyltryptamine), since the two are similar.
If a certified reference standard for MPT becomes available in the next year, we could order it and re-analyze this sample. (The lab *does* have a certified reference standard for MiPT.)
This is not a settled issue, check back for possible updates. If we update this finding it will be flagged as updated.
DrugsData tests all psychoactive drugs including ecstasy tablets, powders, research chemicals, novel pschoactive substances, and other drugs through our DEA-licensed laboratory. Ecstasy/Molly tablets cost $100. Recreational drug powder/crystal/blotter costs $100. Pharmaceuticals, supplements and all others cost $150 per analysis.
Should the public have access to independent analysis of the products they consume?
The vast majority of analyses of over-the-counter, prescription, and recreational drugs are performed in secret with no independent oversite or review. No other historical record, free from politically-controlled agencies, is currently available in North America nor most other parts of the world.
DrugsData, a project of Erowid Center, needs the support of professionals, students, parents, individuals with means, and small foundations for a total yearly budget of around $120,000 USD. Erowid Center's general budget and the co-pays we require fund most of this cost.
