There's plenty of fake scam ones but you gotta find the right links for legit ones.
I use the markets over Tor tho. TG is terrible OPSEC. But most people use TG for convenience.
I got a weed prescription, do the occasional Mandy roll, acid trip, 2C-B, shrooms, DMT trips, sometimes the odd bit of codeine, DHC, morphine, Xanax, Valium, etc.
Just took delivery of 5g MDMA + 100x DHC's as landing gear.
