Naphyrone was horrible mate. Now if it really was naph, I don't know. But the stuff lasted too long, gave you body cramps a few days after using it, which was weird. The 'high' lasted only an hour and the rest of the time you are just suffering, waiting for it to ware off.
I hated MDPV also, that stuff is the devil mate! some people love it, but I like my sleep, and I hate not being able to sleep for over a day, drives me nuts!
You guys should try Diamond Dust from MP when they get it back in stock, now that is amazing!
