Thank you for your response. I know GBL and 1,4 BDO taste bad but I never knew the GHB also tasted bad, I thought that GHB would be tasteless due to it being sometimes used to spike peoples drugs.
I know mixing 10g of GHB with 400ml of 70% ethanol would produce something that is 100% able to kill, especially when mixed with xanax.
Also I never knew GBL was legal in the UK, I never was able to find anything containing it, if you can could you give me a link to where one sells it via pm.
The reality is, it's not used to spike people. It was just a scare tactic to slander gay people back in the day, who were the main consumers of G as a party drug.
Sodium GHB tastes INCREDIBLY salty. A dose that's strong enough to intoxicate someone will make your drink taste saltier than the ocean.
GBL tastes like burnt plastic, I heard that 1,4-BDO tastes similar but I don't know.
Potassium GHB is said to taste like "liquorice", kind of aniseed-y instead of salty. This stuff is pretty rare in the wild, but can be made with Potassium Hydroxide instead of Sodium Hydroxide. I don't know if the taste is actually any better. For what it's worth, Potassium is less toxic re seizures etc.
Magnesium and Calcium GHB I have never even heard of, though google confirms that a medication containing them exists: XYWAV. The taste is most definitely different, but in which way? Who knows. These were probably also never used to spike people as they aren't sold illicitly at all really.
Yeah mixing G and alcohol would increase the chances of success massively, especially if you add a benzo. But realistically, you still have the same issue of vomiting.
Also when choosing a benzo, go for Diazepam (Valium) over Alprazolam (Xanax) as the former is better at inducing sleep, the latter is better for anxiety.
