This May another obscenely rare psychedelic and I crossed paths. This is a story about Aleph-2 , the amphetamine analogue of 2C-T-2. In PIHKAL, the Doctor notes that, in his experience, the Aleph compounds have very unpredictable dose/response curves.

Summary
ALEPH-2 is an extremely rare psychedelic amphetamine in the ALEPH and 2C-T family, combining anxiolytic warmth with classic phenethylamine visuals and intellectual stimulation. Almost no modern toxicology data exists; avoid combining with serotonergic or stimulating substances and dose with extreme caution. The ALEPH series is known for highly unpredictable individual dose-response curves - the same dose may produce markedly different effects between individuals or even in the same person on different occasions.
Perspectives
“There was a warm feeling in the total body and a light pressure in the head that changed with time into the feeling of a balloon without any anatomical definition. The usual color perception was not very much increased, and my vision was not sharpened as it was with DOM. Rather, I noticed waves of movement, very smooth and not too busy. Both my tactile perception and auditory acuity were enhanced. The main effect for me was, paradoxically, an easier handling of the outer world. None of the jitters of amphetamine. The body feeling is good, healthy, and I am at peace with the body-mind dualism. These are pretty much personal comments—I will write up the pharmacological points later.”

Based on reports from:
Tolerance
Build-up
develops over days to weeks of regular use
Reset
3–7 days for acute; 1–3 weeks for full reset
Tolerance Decay
Half tolerance
3d
Baseline
~21d
As with classical psychedelics, acute tolerance appears after a single robust session and decays over about 1–2 weeks. Exact kinetics for ALEPH‑2 are not characterized; values extrapolated from broader psychedelic literature and user reports. Data quality: anecdotal.
