Another point to ponder re: purity
Say Johnny Wooklord, the biggest distributor of LSD at your festival, claims to have so-called "250 mic heddy phat doses marinated in a jar with owsley's brain," a beautiful, multicolor, commercial grade blotter art, but they'll run you 100/400/3500/20k and then Jimmy Business, a small time arbitrageur of cheap acid from one place to expensive acid from another place, is selling properly dosed (10mcg/2.5in^2 i.e. 100mcg/hit) blotters with 100mcg pure d-LSD equivalent (% purity of the raw crystal nothwithstanding), and those are more reasonbly priced, say (and this would be outrageously expensive back in the day, but we're not back in the day anymore, are we?) 10/70/300/2000/14k. Now, which product would you rather buy?
(Edit to add: price schemes pulled wholesale out of my ass. Just to illustrate my point. Don't worry people, I have no idea what acid actually costs these days, and when I was playing ball, it cost considerably less than above, but, you known, inflation and the stormfucking the market took after Ulbricht unleashed his beast to the masses)
Who would you rather do business with? Of course interpersonal factors become a big deal here, but the bang for your buck is clearly with the operation which makes less noise about itself, which, in general terms, is a good thing in illicit marketplace: Johnny W makes a great deal of claims about his product and gets a decent bit of cash off custies and abject amateurs, in this case, they're lucky because they ran into him, because the next tent over they were selling some 2,5I-NBOMe, or something even nastier. But if you catch up with Jimmy Biz, you're probably going to find yourself in an informal setting with nicer people and better quality stuff, again, mcg for mcg or perhaps hit for hit.
And your own mental perception of the trip will be affected: if you got Johnny's doses, you might feel like you've got some of the strongest shit thats's been unleased on mankind since that first vial of Delysd, and go anywhere with that; Jimmy Biz will probably smoke a doob with you and see how you enjoy it or, failing that, will probably hook you up in some way because he needs the business and you need work. Unfortunately, a lot of Jimmy Biz types turn into Johhny Wooks, and you gotta look out for that. Some of them will stay true though, and some of them will drop out of the whole business for the straight life. As far as darknet market vendors, I know fuckall, I couldn't possibly recommend you buy doses from an email address, and much less so testify for their strength.
Seek personal engagement, not digitally mediated bullshit which is basically being a geek at a Bloomberg machine figuring out to edge some α from different products from different disembodied entities with whom you communicate through some obscurantian technology that to you is almost inexplicable. Please, don't go that way. Network, socialize, and find good folks, they do exist. The people who sourced you your drugs in your OP may just be these good people with these drugs, but what is upsetting a lot of us, besides the fact that you are probably factually wrong, is the grandiose you tone are taking about how incredible your experience, how high quality the drugs you, because, why? Headier than thou? Or are you trolling for people to ask you for sources? (Big time against the rules) Or simple brag, thinking that quality of drugs adds inches to your dick? Believe me, it doesn't.
It just annoys us more seasoned folks who've been around the circuit a few times to have someone come in without any building trust and being spoken for will just waltz in here and tell us that our shit doesn't measure up to, what, some kind of mystical experience that the guy had. Well, obviously... heroin makes you feel noddy, molly makes you feel huggy, speed makes you feel speedy, acid makes you feel trippy ... which is a drug effect. I.e., the drug effect, as perceived by your source code/soul/spirit/homunculus/what ever thing you are, is taking a hold of you and altering your preceptions. You should taken an aspirin when you get a headache, a tab when you've got nothing to do, a god set/setting and the time to do it, the molly at a party, the heroin, well, unless you didn't ... but you get my point. Your post basically boils down to, "I got really good drugs. I got really high. 90% of you will never be as high as I was. MUAHAHAHAHAHA!"
Oh yeah, if anyone has anything contribute feel free to distribute, but I don't think much exists beyond what's been said, supra, this is pretty much a dicksizing and/or "WHAT DID I TAKE THREAD" which is against the rules and a bad idea. Anyone showing up here and claiming to have "a grip of drugs" (RIP bro) is either asking for trouble or asking for it to be brought upon themselves. Not saying this is what OP is saying ,but that what this can easily degenerate into shadiness
Anyhoo. Thanks for listening,
