Summary
1P-ETH-LAD is a propionyl prodrug of ETH-LAD that rapidly de-acylates in human serum to yield the active compound ETH-LAD. It is reported to be moderately to significantly more potent than LSD by weight. Start with low doses (50 ug or less) if inexperienced.

Start low, go slow, and test your substances.
Custom Units carry a single dose per route, so the full ranges live in the reference above. A route's suggested dose is the midpoint of its common range. Ranges are harm-reduction guidance, not a prescription.

100ug 1P-ETH-LAD trip. T:00:00 It was 11:00, 31/01/2016. The flat was a little cold, but otherwise the setting was good. My fiancée was in the bedroom, not feeling well, so this was in essence a solo trip.
I'm a bit at the cutting edge of psychedelic research, confidently exposing myself to completely novel Lysergamide RC's supplied by the most trusted RC vendor known to man. Some might find this pass-time dangerous, I find it fascinating.
