Which major requires less chemistry? Because to me, chem always seemed like an endless list of things to memorize: polyatomic ions, acids, bases, electron charges, drawing Lewis-dot diagrams, etc ad nauseum...

  • Neuroscience
  • Pharmacology
  • what else?

500k available CS jobs in the USA an industry that will never have enough people to be (oversaturated) at least in the next 10 years. Maybe web development sure. Any 12 year old with a computer could be a "web dev" CS is literally the highest paying degree you can get right now.
And there will only be higher demand with new technologies like virtual reality. CS really has endless possibilities of application, not to mention you don't need to work for someone, you could always do your own thing, and still make good money, or even freelance. If you do things for the money though you will realize you really really hate what you're doing.

>DId the bare minimum just to get good grades

Neuroscience probably has less chemistry but both of those majors are pretty heavy memorization. You will have to memorize drug/metabolic pathways. At least in chemistry there is an internal logic to it once you get the basics down, but with molecular pathways it's almost senseless memorization with having to know all the different (often randomly named) parts and how they interact with each other.

So, I found a clearnet source for both Etizolam and Clon, but then upon checkout, this shit comes up:

>We will need a detailed account of your research methodology though before shipping any order. This an include how you will be utilizing the chemicals, what equipment is used, anticipated results, etc.

What is some things I can say? Obviously they know people are just ingesting them, yet they still have the disclaimer for Not For Human Consumption. That's fine.

But I've never seen this type of bullzhit.

anyone a science student or chemistry student or actual chemist or anything? I know some people say they can test for purity of the drugs. What would be used for that? Some type of ethanol, beakers, syringes, etc?

Thanks.

If you did an A/B on a bunch of used cottons with some blood in the mix as well, what would the blood do if you add base->non-polar extract->add acid to neutralize.

Or wait, now I forget... ^ that sounds like "B/A'... if you're starting with traces of heroin-hcl leftover, then you would start with the base, riiiight....

what are your criteria for starting molecules?
if you go with B i think that deprotonating acetylacetone, which can be made via the claisen condensation of ethylethanoate and acetone, and then jamming that on 4-"something"hexan-1-ol would work if you the something is a good leaving group, like a trimetyl ammonium thingy for example.

This is an email I sent out, but feel free to take a whack at it.

From the given information on the FAQ:
>Then we perform a qualitative analysis on each component identified where possible,
>comparing each substance with a pure reference standard.
>Our results directly provide the result of the salt of the substance, as we’re
>using a salt as a reference standard. The quantitative results are provided using
>a calibration curve from a reference standard.

as well as the techniques listed here https://energycontrol-international.org/drug-testing-service
It seems that almost all of those techniques can be used to generate a quantitative purity result, e.g. GCMS, LCMS, HPLC, UV/Vis.

So can you try to fill in the blanks here for me?

A reference standard is a documented, authentic sample of the chemical you are looking to analyse for.

You dilute the reference standard in solvent at a range of concentrations, generally 5 different conc. are used for a good calibration curve.

You set up the instrument (GC/MS/HPLC/UV ect.) and inject each of those 5 standards you prepared.

The plot of detector response (peak area) as a function of each standard concentration should be roughly linear, fit a least squares line and use the equation of that line to calculate the amount of analyte in your test sample based on the peak area it gives.

this process is not nearly as simple as it sounds.

if you really want to test the lab's accuracy weight out a decent sized sample of a compound (~500 mg) and grind it well, then submit two samples of the same grind. They should be within 10% or so of each other

  3. caffeine about 1:1 to lower MP
  4. iso evaporated onto foil

The end result way too baking soda and some went into my throat in scalding liquid form. Good thing heroin kills pain.

  • Is it safe to vape that baking soda?
  • If I used soda ash, would it be safe to vape that too?

Its called freezing point depression. Pretty cool shit, back inna days people determined purity and molecular weight with that effect.

Vaping either baking powder or any inorganic nontoxic base wont be a problem unless you inhale too hard.

Concerning the solvent, just look for the swg drugs heroin dossier( guess thats what your chart is based on?) or someother tables to check which solvent is useable for both the HCl and the freebase. You dont have to add the caffeine while thd h is still is in solution as long as you mix it thoroughly

Id recommend using as little solvent as possible while not slowing the dissolution of the base down too much and installing gentoo just to be safe

Deprotection. Sorry, I was /benz/ed as shit when I decided to legitpost on a few boards. I mean, the information is still good.
Fuck I should teach more when I'm benzed no i really shouldn't

No. You use as little water as possible with an ice bath and then do a vacuum filtration when the freebase precipitates. I don't see why an extraction after freebasing wouldn't work. However, I don't really work with that stuff as much and have no idea if it acts like morphine chemically (it shouldn't due to no active OH groups). Alternatively, You could do the boil down and then acetylate the morphine back into diamorphine.

I'm too chemical, though. I would look up conversion between #3 and #4 or whatever on the internet. Homebaking is much easier than what I would do.

So I used sodium carbonate super-saturated (pH was ~10-11) then added some heroin salt -> tried using hexane to extract it -> evaporated.
Evaporating is always the worst step for me, because unless you're doing a massive batch, you end up with such a small amount of freebase residue, so for max efficiency I try to evaporate directly onto foil, which means I try to make a wide dish out of foil, which often ends up breaking and leaking all over my desk, BUT when it does work Im able to vape right off that foil. The alternative would be to put it solid container, but there's ALWAYS some waste when you try to scrape it all up.

So did it get me high? barely. Not enough. Wasteful.
