That's true. I haven't heard of people cutting LSD with other research chemicals. I'm not an expert, but from what I've gathered reading around is that other drugs that are effective at that dosage are sometimes easier to get ahold of but not necessarily cheaper. It's not like cocaine where it's very lucrative to cut the drug with fillers. Coke, after all, is sold by weight while LSD is at such small amounts I'm not sure what cutting it would really gain you. I feel like they're more likely to give you something under dosed and call it a day. I think it is possible to mail in a dose to a lab that can analyze it on a molecular level. Personally, I think if you can prove the existence of LSD, I would feel reasonably confident that that's the only active ingredient. But you're right, there's no way to know for sure. In any case, one should be careful with these types of things.
