    Summary dose.wiki

    4C-D (Ariadne) is a rare psychedelic phenethylamine first synthesized by Alexander Shulgin in 1968. It was developed by Bristol Laboratories and reached phase 3 clinical trials as an antidepressant and motivational enhancer before being discontinued for economic reasons. Unlike typical psychedelics, 4C-D produces minimal hallucinogenic effects even at high doses, instead causing mental alertness, mood enhancement, and mild stimulation.

    Perspectives

    “I believe that my mood has distinctly improved, and my sleep that evening was excellent. This is physically benign.”

    Tolerance Decay

    Pattern assumed similar to other serotonergic psychedelics: rapid short-term tolerance that decays over ~1โ€“2 weeks. Evidence quality is low and based on analogy plus limited user reports.

    Aggregated from 5 Erowid experience reports

    Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect, something witnessed, or "did not happen" count too). Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.

One of those is BOD, and the other is 4C-D (2,5-dimethoxy-alpha-ethyl-4-methylphenethylamine), nicknamed ARIADNE (one of his "classic ladies") in PIHKAL.

    I wouldn't post this report (really just some notes,) except there's so little info out there I thought it might be worth it. There are just WAY too many variables to get much useful info out of this experience. So, three days after a weird 5-MeO-MiPT experience, I tried this for the first time.

    Got my hands on the substance and, having nothing to do today, I decided to give her a go. 9:13 a.m. (0:00)- Feeling great today, woke up right before 6, had a donut stick and a cup of coffee, had nothing to eat for more than 12 hours prior to this.
