Summary
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
Build-up
develops over days to weeks of regular use

3โ7 days for acute; 1โ3 weeks for full reset
Tolerance Decay
Full tolerance

Half tolerance

Baseline
~21d
Acute tolerance: develops within a single session โ the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
Pattern assumed similar to other serotonergic psychedelics: rapid short-term tolerance that decays over ~1โ2 weeks. Evidence quality is low and based on analogy plus limited user reports.

3:00pm (T+0:00) - Ingested 35mg of 4C-D HCl. This is my second trial. My first trial was at 50mg + a 25mg booster an hour in. I intended for my next trial to be at 100mg to see how the psychedelic effects develop at a higher dose, but I have tripped thrice in the past 2 weeks (or at least taken something psychedelic -...

4C-D ("ARIADNE"), Trial #2 "Appreciation of the Ordinary" 4-19-2019 by Xorkoth โ 3:00pm (T+0:00) - Ingested 35mg of 4C-D HCl. This is my second trial. My first trial was at 50mg + a 25mg booster an hour in.

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.
