I really don't know how to feel about this compound. I recently tried it again at ~500ug and felt that this seemingly large dose might have been perfect for a social or even public setting as opposed to the more private one chosen. I would not describe myself as a hardhead but I again found myself somewhat underwhelmed; by contrast, 400ug of LSD is plenty for me to have a fully psychedelic experience, but this trip was very easily controlled at all times. My trip was very visual, probably more so than an equivalent dose of LSD, and very physically pleasurable (fantastically erotic) but again seemed to lack a lot of the "push" in terms of mental effects that LSD has. I find it interesting that Shulgin chose to describe the missing aspect of LSD from AL-LAD as "sinister"; while in a way this description may be appropriate, I feel that what AL-LAD winds up lacking is some of the exploratory depth that LSD offers. However, this is not wholly negative, as like Shulgin I got the impression that it would be virtually impossible to have a bad time on this compound, at any dose, though I doubt I'll bother going any higher.
On duration/timing: again, I experienced effects that were almost barely noticeable for over two hours after ingestion (I swallowed immediately this time, rather than allowing for any buccal/sublingual absorption) and then rushed up to a peak very quickly after that. The total trip duration is notably shorter than LSD, as I was actually able to get several hours of sleep just 10 hours after taking it. It's worth noting again how clean this substance is, as sleep came quite easily following the trip.
