Ah, alcohol... What concentration?
The thing is that everyone seems to say different things about stability. this page suggests that when not in solution it's more stable. There's a guy here saying that storage in ethanol causes loss of potency. Here it's recommended to keep it dry and same here, but they're clearly having blotter in mind. This one says it's very unstable as blotter but can be kept in aqueous with preservatives.
Haven't really tried the 1P yet. Did a 50 mic test dose about 6 weeks ago and not much happened. Last week was a very intense mushroom trip, so I'm going to stay sober for at least 4 weeks or so before going for the 1P.
