It works fine. It's a simple acid extraction. The same could be done with just citric acid instead of lemon juice. Citric acid is primarily what gives lemon juice it's flavor and what's responsible for helping extract the LSA from the seeds. You can mix some citric acid and water and sugar, and it'll taste very much like lemon juice, although lemon juice is much better for you.
On a side note, raw lemon juice contains an enzyme that destroys strychnine. So, if you've ever had some acid and you thought it contained strychnine, you can put it in some lemon juice overnight and the strychnine will be destroyed. Actually, most acid people think has strychnine really doesn't. Acid itself can have effects similar to strychnine, depending on the impurities and breakdown products normally present in LSD.
You may remember me as 69Ron. I was suspended years ago for selling bunk products under false pretenses. I try to sneak back from time to time under different names, but unfortunately, the moderators of the DMT-Nexus are infinitely smarter than I am.
If you see me at the waterpark, please say hello. I'll be the delusional 50 something in the American flag Speedo, oiling up his monster guns while responding to imaginary requests for selfies from invisible teenage girls.
