PLEASE, LET ME WARN YOU! Use it again ONLY after a coulple of months!
Or if you CARE about your brain cells, don't use it anymore.
This drug is way worse than cocaine itself, it can wreck a havoc in your neurons (axonal damage).
Please, please... do some research... never use it every weekend, or you may end up like a lot of people in this forum suffering form long term comedowns, they usually last longer than a year. BE VERY CAREFUL. You used 300mg upfront, first time doing it.. I can't even imagine how you gonna do this the next time or when.. can't even imagine. Probably you gonna be just as wreckless as this first time and you gonna do it again soon I presume.
Just... be... careful! This is not a party drug, it's a very dangerous substance that should be used very cautiously, or if not, never used.
