I've tried several vendors over the last few years...had some good experiences and some bad, been scammed once (fuck you k&alpstore!), and mainly spent way too much time trying to find a reliable, consistent supply of ketamine. I'm not into reviews AT ALL, but I figured I've taken so much from the community here that I should give something back, regardless of how minimal.
My top two ketamine vendors are Symbiosis and, now, KingofClubs.
Symbiosis - offers s-isomer ketamine (which I prefer) shipped from UK.
PROS: very good product and has always been consistent (at least the batches that I was sent). It is also pretty cheap - I believe I was paying around $30/g at the volume I was purchasing. Always has a clean ketamine high that is more dissociative psychedelia than drunken wonkfest. Comes broken down into super fine crystals ready for your nose.
CONS: international. I've had it take anywhere from 10 to 23 days to receive - although the 23 days was around the holiday season, so I'm sure that didn't help things. stealth is pretty basic, but it's low profile and sealed a few times and blends nicely.
KingofClubs - also offers s-isomer ketamine shipped from Trump's America.
PROS: ridiculously fast shipping. 3 days to my door on a saturday delivery. like, he/she/they must have put it in the mail an hour after I ordered. this may have been the fastest shipping I've ever experienced on the dnm. It arrives in big chunky rocks (I honestly had not seen such big lumps of ket before) but they crush up nicely with minimal effort. This ketamine is also very good with a nice menthol essence to it. In fact, I could not tell the difference between Symbiosis and KoC in terms of product potency and high even when I went back and forth between them throughout the evening. Literally, the only difference I noticed was the menthol...may have taken slightly longer to hit, but it may have been I was high on ketamine and a little spaced. It is a little more expensive at about $40/g at the volume I was purchasing...but in my opinion, completely worth it to not have to worry about customs and to receive it in a few days.
CONS: stealth is very basic here as well. however, I feel much more confident in KoC stealth being domestic than I do Symbiosis crossing international borders. Also, (maybe I'm stretching here to find a con...) but KoC sort of comes and goes on the markets. I was checking his shop every day until I saw he had some listings up. This is kind of annoying for a buyer, but I know if I was a vendor I'd do the same thing - get stock, sell stock, vacation, repeat.
CONCLUSION: if you reside in the sinking ship helmed by Captain Trump, KingofClubs is your guy for quality ketamine at a fair price with super fast delivery.
EDIT: I should mention that neither vendor has incentivized this review. In fact, they wouldn't even know that I've purchased from them as my reddit name differs from market names.
Celebrity Vendor Death Match....Bahahahahahaaaa!!!!!
