Unless you reagent test it, you can't even be sure you're getting real LSD. In my area, 25i is prevalent and being sold as acid, and there have been hospitalizations due to overdoses of 25i by people who, thinking it's acid and knowing they can take 5 to 8 hits of real acid, take 5 to 8 hits of 25i totaling around 6 to 8.4mg according to the dose measurements discovered (1.2mg per hit).
Luckily, the people I know who are selling, are well aware of the dangers, and refuse to sell more than 2 to a person. However, not everyone they sell quantity to is as ethical.
Test it before consuming it, for your own safety, and to not become another statistic used to support anti-drug laws. I received some of what I thought was the real stuff until I tasted the chemical taste, and noticed the 2C body high. Thankfully I only did one hit.
Later on I tried 3 hits, and had to pop a ton of sedatives due to a spiking BP and heart rate.
