If you swallow the blotter immediately any 2c-x-nbxx should be inactive (there is some debate about large oral doses being active or not but one blotter isn't enough for this), which leaves you with some other lysergamide (al-lad, eth-lad, ald-52, 1p-lsd, 1p-eth-lad, lsz... of these all are decent, ald-52 and 1p-lsd are very close to lsd so you should be good, al-lad is a shorter lasting lsd with more visuals and less mind fuck idk if that sounds good to you, eth-lad is similar to lsd but more visual slightly more potent and has a bit of a different head space but is an excellent psychedelic, 1p-eth-lad is extremely rare but otherwise very similar to eth-lad, lsz is nothing special and probably the worst of the bunch but is also extremely rare and unlikely to be on your blotter) although most of these are sold as such since they cost more than lsd and make for a bad scam (the whole point of a scam is passing off something cheaper as something more expensive and that's where this fails), a dox (possible since they are cheaper, but they are considered good by most and just one blotter should be safe, but the duration might be a bit long) or something exotic like 5-meo-amt or bromodragonfly (this one is pretty bad but extremely rare).
Get a test kit and you should be able to tell if it is a dox or a lysergamide or bromodragonfly or 2c-x-nbxx (wont work anyway if you just swallow the tab).
This leaves you with some lysergamide on the blotter (not sure if you can tell 5-meo-amt apart with standard reagents). If you want to know which exact lysergamide it is you'll need a lab test.
