What's so special about LSD? LSD is LSD.
Gel tabs are gelatin which won't absorb well intranasally, I suspect that's the main question of the thread, sorry if I misread here.
Gel tabs are surprisingly common these days.
Insanely so, they're tougher to reagent test though which isn't great. What is nice is that they typically can have much higher doses than blotter and appear to degrade less.
@ronboslon Only liquid LSD can be used intranasally, though I personally prefer it as eye drops. You can make these out of blotter by taking say, five drops of water in a small vial, and saturating as many tabs as possible in it for up to a few hours in a dark, dry space below 70°F. Do it a few times to the same tabs, the first saline pull doesn't get everything out of the paper, give it at least three different soaks and then add them all together. Sometimes I've shredded the paper before infusion but then it requires filtering out the paper bits before putting it in my eyes or sinuses. Also, pH test your water and balance with ascorbic acid if you need to, to keep it just slightly more acidic than neutral. Preferably do this saline infusion process under only red or yellow light.
Intranasally administering liquid LSD I've only done once, I dropped liquid in my nose and held my head upside down on the couch. It was forgettable compared to oral or eyedrop administration, imo. Gel tabs don't dissolve well, they only work orally.
Edit: A crushed up tablet of LSD could do this too, but they're exceptionally rare.
