Abstract

fetched live from OpenAlex

1H NMR spectra of 43 alleged psychedelic tryptamines (2-(1H-indol-3-yl)ethan-1-amines) and benzofuran analogues (2-(1-benzofuran-3-yl)ethan-1-amines) from grey-market internet vendors across North America and Europe were acquired and compared. Tryptamines having mono- or di- alkyl, cyclopropyl, or allyl amine substituents and/or substitution of the indole/benzofuran ring by acetyloxy, hydroxy, methoxy, or methyl groups were analysed. 1H NMR spectra for some of these compounds have not been previously reported to my knowledge. The spectrum of each analyte is consistent with the compound as labelled and sold. None of the analytes was found to be unequivocally misrepresented. This collection of experimentally uniform spectra may help forensic and harm-reduction organizations identify these compounds, some of which appear only sporadically. The complete spectra are provided as supplementary data.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
