GHB, all you need is an industrial cleaner (GBL), chemical drain cleaner, distilled water and some pH strips.
Put 135g of GBL and 63g drain cleaner in a stainless pan with half a cup of distilled water on a low heat for an hour with the lid on the pan. After that add the contents of the pan to a measuring cup, add water till it's 1l. Test the pH, if higher then 7.5 add some vinegar to bring it down.
Presto, you can now easily get into a girls pants. And after 12 hours it's untraceable.
