At the University of California Medical Center(sic),
Scully uncovered the scientific paper Hofmann and a colleague had
published on the drug. From the US Patent Office he drew patent
number 2,810,723, lodged by Sandoz with production details. In The
Hallucinogens co-authored by Osmond and Hofmann, Scully discovered
a table comparing the effects of ALD and other drugs in the same
family.
The table suggested that ALD might actually have advantages over
LSD, reducing any side effects but achieving a stronger trip.
Measurements of brain waves while people were taking the two drugs
showed that while LSD produced brain waves associated with intense
concentration and anxiety, ALD produced brain waves showing a more
relaxed mental state.

So if this is actually true, it may turn out that there is a little difference after all.
Feeling relatively more gently eased in and relaxed would match what I - if anything - would suspect from delays in kinetics, and it is also a match for many descriptions of 4-AcO-DMT including my own. I also tried synthetic 4-HO-DMT and in comparison especially the comeup was a lot more abrupt, anxious, in-your-face but also visually interesting. 4-AcO-DMT sneaks up on me a lot more while still being every bit as deeply entrancing and sneakily encroaching or more.
Am interested to see how 1P and ALD align with this subjectively.
