1. They're really letting you do this?
2. You know this is extremely illegal? People use the darkweb and several other anonymity tools to sell these same drugs. Be smart..
Disclaimer:
There are multiple side effects of these drugs including:
fast, pounding, or uneven heartbeats;
feeling light-headed, fainting;
increased blood pressure (severe headache, blurred vision, trouble concentrating, chest pain, numbness, seizure); or
tremor, restlessness, hallucinations, unusual behavior, or motor tics (muscle twitches).
I do not advocate the use of drugs and advise you to not buy anything remotely illegal on the forums.
@OP: Please try selling your goods on the darknet, and try to build your rep with something else, such as altcoin trades or gift cards
