OP is ~23 at the time and that seems like a very natural age for that experiment.

One of the most interesting things about reading Robert Anton Wilson's more autobiographical stuff (Cosmic Trigger? Prometheus Rising?) is that when he talks about doing LSD for the first time with Leary and co, all these guys were in their 30s!! I can't imagine how shocking it would be to have gotten that far in your life, believing and committing to the perceptions you've had, only to have them ripped apart by those megadoses (by today's standards) of LSD.

I think that is also why they made such good use of the experiences. Having more life experience, they might have been even more appreciative of the new insight.
