Don't ship liquids. I have lost count of how many times I've said this. This is because liquids are a reason to believe it could be a mail bomb, which comes reason to do anything to your package. Suspected package + then the detection of liquid = guaranteed interception. Postal inspectors have machines for detecting liquids in the post, and they are like 100% effective at what they do, but I don't know much else about them.LSD blotter on the other hand you don't even need to vacuum pack. Hell, you could have an box of A4 worth of LSD and it'd fly straight through (not advising that though, lol). LSD has the lowest particulate transmission rate of any common illegal drug because ~150 micrograms is a really tiny amount.In fact, I cannot think of a better product to transact on the silk road in terms of security/risk tradeoff. Profit is another thing, but having your own LSD lab would be a veritable gold mine. You'd be laughing all the way to the bank and then they'd be like: "lol, I need to see some ID for all this giant pile of money, lol" and you'd be like "lol no dude, lol, I own all the banks as well, lol".
