Lots of people buy random ass gas station "supplements" as some are research chemicals being sold under other names. Unfortunately the real fun stuff no longer pop up after the DEA cracked down on it. Here's some examples of different RCs that were sold in gas stations.
2C-B a serotonergic psychedelic was sold as an aphrodisiac under the brand name erox and nexus
MDPV and 4-MMC two empathogens similar to MDMA where sold as "bath salts" under several brand names including ivory wave, purple wave, and white knight
Famously a whole bunch of synthetic cannabinoid were sold under the brand name K2 and Spice
DMAA a stimulate was sold under the brand iced diamonds and many other brands
I disagree as what looks more suspicious, a computer with tor on it or a computer that has nothing on it because tor is on your flash drive?
