I don't know if I can't trust this site. I already have Sn but I found know that I could buy N for 350€ but not sure if the site MI is legit
That is most likely a scam.
No idea what MI stands for, but they may send you something that turns out not to be N (or they send nothing all).
Price is too low and there simply are no labs that manufacture N.
Neither legally nor illegally.
N is difficult and resource-intensive to produce.
That's why there are only two certified official labs that produce veterinary N. One of which blew up in an accident 2 yrs ago, leading to a global shortage of veterinary N.
N for humans is not produced anymore. Hasn't been for at least 20+ years.
There simply is no market for it (outside of the few people here or on Exit's boards).
N also can't be produced in backyard labs because it requires
- appropriate equipment
- ingredients that are hard to source
- extensive knowledge of an actual, trained chemist
Please don't get scammed.
