Storing - Help with Liquid LSD

[Dusted]

I know this guy that has some really good liquid LSD, the problem is the only droppers he has access to drop out too big and he loses L & money. He tried dropping on paper and it held really good while its still wet, Tried tarts and sugar cubes and they only hold while they are wet too. If dropped on tongue works fine. if dropped on anything and eaten right away works fine how could go about putting on paper without losing L? Someone please help
