5/5, ideal transaction. I made an order for 1 gram of methamphetamine and it arrived the same week. The bag was overweight, roughly 1.3 grams of chunks and shards of crystal. That is the most additional product I've received so far with the ~7 vendors I've tried from SR1 and BSM. Purchase went smoothly and NA responds quickly to messages. Stealth was typical, neither exceptional nor egregious.
The product burned a lot stronger upon insufflation and felt more potent per milligram than the stuff I received from Zohar and DrWhite some months back. So tentatively I'd say NarcoticsAnonymous > Zohar > DrWhite in terms of quality of the methamphetamine from BSM vendors. I do realize batches of product vary over time with the same vendor though, so this of course won't necessarily hold true in the future.
Overall, NA's product was great for my mood and focus, and I got plenty of work done with it. Would recommend. Bear in mind this is my only order from them so far, and for a 1 gram amount, so please take my anecdotal experience along with a crystal (of salt).
