    Home Laboratory: DIY Fume Hood

    In this thread I will document my build of a poor man's fume hood. It may not look like it yet, but this cardboard box will become a functional fume hood in few days.

    Using Artificial Intelligence Technologies to Expose Darknet Opioid Traffickers

    The keywords iDarkParser, iDeeplearner, AlphaDetective don't yield anything in search engines. The papers probably don't reference these terms at all and it'll take a serious effort to comb through papers linked to WVURC.

    Using Artificial Intelligence Technologies to Expose Darknet Opioid Traffickers

    Interesting stuff. The audit report does not contain much relevant information for us but it can be a springboard towards the published research papers that actually reveal the methods and techniques used. It would be good to link those, I'll try to find some and link them here.

    I looking seller for MDMA MMC Ket

    Looking for a vendor 
    You can check existing offers in the Drug Market section. Also, it's helpful to mention the region, e.g. USA, North America, EU, etc, unless you are willing to take the extra risk with international shipping and customs.

    The simplest recipe for crystal Mephedrone

    Thank you for the answers! Few more points to clarify, if you don't mind: 3. Is it better to first add all acetone (e.g. 400 ml) and then add HCl 1 drop/s, or first mix 40 ml of HCl in 400 ml of acetone and then add this mixture slowly in small portions? 7. I don't think spilling solvents like...

    3-CMC freebase recipe needed

    I am no expert but I hazard to guess that the process is the same as for 4-MMC but you use 2-Bromo-3'-chloropropiophenone (CAS 34911-51-8) instead of 2-Bromo-4'-methylpropiophenone (CAS 1451-82-7). The rest should be the same.

    Crystallize phenacetin

    Question 
    Like with anything else: dissolve it in the right solvent and let the solvent evaporate without disturbing the solution in the process. Phenacetin does not dissolve in water. I could find that it dissolves well in pyrimidine, other solvents that work are acetone or chloroform. Based on a quick...

    Converting Crypto To Accesible Cash?

    Or you can just old school launder the money and legalize it. I can't imagine how buying property with cash that is not legalized can seem like a good idea to anyone. Start a business, put up a website that sells a service or paintings or whatever, funnel money in as crypto, pay tax on it, sell...

    filtration of the odour

    Considering a small-scale home lab (1 l reactor, using chemicals such as DCM, 2b4mp, methylamine, HCl, acetone) vented outside without any filters, what is the distance where neighbors and passers by can smell the generated fumes?

    Question 
    I hit up a chinese vendor on telegram last night and learned one important detail. Their MOQ (minimum order quantity) is like 25 kg, nothing for the small guy.

    The simplest recipe for crystal Mephedrone

    I have a bunch of questions that I hope someone can answer for me. 1. Solvent Benzene is hard to obtain in the EU and after discussing this synthesis I've decided to use DCM instead. The original recipe uses 200 ml of benzene but it seems that when DCM is used, 500 ml is a popular amount for...

    How long can you store injectable solution drawn in a syringe?

    Thank you for the detailed comment. I have been thinking along the same lines: filtering does not remove viruses (too small) which is why I opt for sterilization by heat at 99 °C as the primary method that sterilizes the solution. I plan to prepare batches of no more than five shots at a time...

    has anyone here tried IV 4-MMC Mephedrone?

    That is is (particularly) destructive to veins. I guess that a medical professional would argue that all illicit substances administered through IV are destructive to veins, so I wonder if mmc/cmc stands out in this regard.

Vzdy na sve prave jmeno a adresu, protoze jakekoli falesne jmena nebo snaha vyuzit neobydleny barak vedle jen veci komplikuji a zvysuji podezreni. PO box na poste je stejne podlozeny smlouvou, kde se pronajimatel...

    How long can you store injectable solution drawn in a syringe?

    Low doses (<100 mg) are notoriously difficult to weigh with precision unless some very-high-precision scales are used. For example, to prepare ketamine for IM, it may be better to prepare a batch of five shots by dissolving 500 mg K in 5 ml of saline solution, instead of weighing 100 mg for one...
