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.”
Dose Information
Dose basis. Human data primarily from Shulgin’s PiHKAL notes and community reports; material is rare and potency appears steeply dose-dependent. (Dose figures and this note are from Drugs.Wiki.)

The PsychonautWiki Journal logging app doesn't include every substance. To track ALEPH-2 there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:

and you get "ALEPH-2 (Substance Search)" with every
route's full dose ladder and timeline, no typing. Works on iOS and
Android (v15+); the format is confirmed by the app's
developer. The manual values below work for older

Description
ALEPH-2 Source: SubstanceSearch (substancesearch.com) Oral dose (mg): threshold 1 · light 2-4 · common 4-6 · strong 6-8 · heavy 8+ Oral duration: onset 0.75-2h · come-up 1-2h · peak 3-6h · offset 4-8h · total 6-18h · after-effects 4-24h Note: ranges are harm-reduction guidance, not a prescription. Start low, go slow, and test your substances.
Tip: for quicker logging you can also add a Custom Unit in the app, e.g. common dose ~ 5 mg (Oral).
The app keeps custom substances simple, so the full dose ranges live in the description text above. Ranges are harm-reduction guidance, not a prescription.
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.
