Fuck which country are you in I'm guessing USA. This is kind of a what have I taken thread but I'll give you some info but all your doing is guessing at best. Note all SGT chemicals are made by a Thai company called star gate technologies hence the SGT. Perhaps CL-2201, or AB-FUBRINACA, it may be SGT-42, then again PB-22, or 5F PB-22, a nice patented chemical such as SGT-24, or then again S-N-(1-amino-3, 3dimerhyl-1-oxobutan-2-yl)-1-5-fluoropenty-1H-indole-3-caboxamide, next we have 1-(5-fluoropentyl)-3-(4-fluoro-1-naphthoyl)indole (this may be AM 2201 not 100% and if so illegal in the USA) there are also a couple of other SGT patented chemicals I have not listed. These substances are almost unknown to science and indeed the entire SGT series have been developed and patented as distant analogues of pre-existing poorly research and almost unknown synthetic noids.
Take my advice and stay away. They have a very high addiction profile. They rapidly raise blood plasma levels and drop again just as rapidly within a short time frame and this is the definition of an addictive substance. Also you will end up smoking like 3 grams or more a day, have a cough like you work in a Russian sulfate factory, the synthetics start become your no.1 passtime/hobby and social activity (the social activity being the process of going to a head shop and buying the crap). Also you will find tolerance builds at a stupid rate and all your spare time and money will go on these noids. You have been warned.
As a side note if your thinking that you can ban the drug by banning SGT42 good luck as it's not even anything to do with the chemical it's just a brand name and it'd be changed overnight and the same crap will be on the shelves of head shops within 24 hours under a different name.
