>>76390682 (OP)an online source. you can go either pharma grade shit made by an actual company for a lot of money, or just buy from a UGL (underground lab) that makes it themselves. For the most part, UGLs are just as good although the QC isn't as good so you can get a shitty batch once in a blue moon.
I can't give you any sources on here, it's against the rules. Can't even do it in /fraud/.
You'll have to pay in crypto most likely.
You'll pay more for a domestic warehouse that can ship to you quickly. I opt to buy from international warehouses. It's cheapest but it takes 2-4 weeks to get to you and can theoretically be seized by customs. You won't get any shit if that happens. Nobody cares. They'll probably reship for free.
There are forums you can go on that have sources and reviews. Look it up.
