I was also worried about this, from what I've read, at least some of the tabs going around are covered with a 1.5mg/blotter layer of Cyclodextrin, which supposedly should provide extra protection... But I'm still not sure of it's shelf-lifeVery interesting compound, I will be following this thread for sure and of course, add my own experience to it if I end up trying it. As someone who trips very rarely, this comment is of some concern to me though:
"I suspect that this material is rather unstable in solution, even as the tartrate in dilute saline, although I cannot guess why that should be. A few months in the dark, at zero degrees and in the absence of air, led to a very real drop in potency, measured by a control assay of a freshly made solution of the same nominal concentration" - A.Shulgin in TIHKAL
One can only hope that the shelf-life proves to be much better on blotter but it doesn't sound good to me. I'm not one to stock pile but even 5 blotters would last me way longer than a few months. Just wanted to put this out there in case someone is about to stock up.
