    So, this friend of mine has a script for 10 mg methylphenidate. The brand name is Sandoz. I was wondering if you can extract these the same way as the brand name Ritalin? The ingriedients in the tablets are:
    -Methylphenidate HCl
    -Calciumphosphate
    -Lactose
    -Wheatstarch
    -Gelatin
    -Magnesium stearate
    -Dutch:Talk (chalk???)

    I've read in another thread that the goodies in Novartis Ritalin can easily be extracted by mixing the thouroughly crushed pills in some kind of cooled alcohol (IPA 70% or higher for example at refigerator temperature [5 degrees celcius]) and filtering it through a coffee filter. Then let the solution evaporate and tadaaa! Pure methylphenidate. I have read that this method also works on Concerta.

    Since Sandoz is the generic chain of Novartis the ingredients are probably exactly the same. I couldn't find the info on the generics in English so I'm just checking with the experts here to make sure.

    Please help me out here so my friend and me can use his script to party once in a while without sniffing chalk!

    The purification is for sniffing, so minor amounts of inactive ingredients aren't a problem.

    Sorry for the rant, i'm high as hell on this shit now (actually like it better then cocaine). Goes well with a few mojito's too!

    I gues Ya'll get the point. Will the alcohol extraction work on this generic? If not, What will? Also, if there is a better or more refined method I'd also like to know, as long as the solvents and such are easy to acquire.

    Thanks!


    UPDATE on the extraction, please read page 2!

    Methylphenidate is a lot more soluble in water than in ethanol, who the fuck would suggest an ethanol extraction? Only if quick evaporation is your intent.
    The gelatin will fuck your extraction up, forget about it. Anything that gels up is shit, sorry. You're better off with novartis'.

    Found this on Gelatin:

    Nothing is known with any certainty as to its chemical constitution, or of the mode in which it is formed from albuminoids. It exhibits in a general way a connexion with that large and important class of animal substances called proteids, being, like them, amorphous, soluble in acids and alkalis, and giving in solution a left-handed rotation of the plane of polarization. Nevertheless, the ordinary well-recognized reactions for proteids are but faintly observed in the case of gelatin, and the only substances which at once and freely precipitate it from solution are mercuric chloride, strong alcohol and tannic acid.

    So that would mean afforementioned alcohol extraction would take out the Gelatin, or am I lost in translation here?

    a methylphenidate extraction would be great to read about,
    any chance of posting a link or two you (or anyone) have found?
    or, i could utfse but i'm lazy.....

    anyway, i have little experience with this compund,
    but i imagine concentrated product could be interesting to work with.

    I would imagine quicker evaporation would be a big advantage so heat doesnt need to get involved, as long as methylphenidate is not relatively insoluble in organic solvents (much liquid would be neeeded. would take longer).


    to the OP -- good post, know about the rant and ramble thing, im still fucking high from last night's benzo binge......

    Methylphenidate hydrochloride is barely soluble in water. Check out Phreex' post in this thread.

    The OP has methylphenidate HCl.

    You guys need to read more carefully

    ^The op is the one that needs to read right. I am fully aware that methylphenidate alone is poorly soluble in water, and just to make things clear, that is useless info since everyone mostly gets it in salt form.

    He says mph HCl is barely soluble, he's obviously completly wrong. It's common sense that most hydrochloride salts are water soluble ffs.

    I guess I did misread it. Now can you help out instead of just being a smart-ass?

    What do you wanna know? I think a concensus was reached. Get the most pure ethanol you can get and extract the pills with that, since the proteinoids will precipitate out of solution.

    Methylphenidate Hcl is very,very soluble in isopropyl alcohol, like most Hcl salts.

    to OP: try to get 100% IPA. It's easy evaporate.

    Well, I was wondering if this was true, and an IPA/ethanol/other alcohol will also get the gelatin out... And if it does will the procedure just be:
    1. Crush pills
    2. Dissolve in IPA
    3. Filter through coffee filter
    4. Evaporate IPA


    Or do I need to let it sit around for a second or whatever?

    By the way: Thanks for helping me out, the noses are grateful

    That sounds fine although if you're going to filter "normally" you'll need to add more alcohol and wait a bit cause obviously the filter is going to get dirty easily, slowing down the solution's flow rate.

    i agree with narutokin on this, even in phreex's guide it says this

    "Methylphenidate hydrochloride is soluble in water, alcohol, and methanol."

    FOr s1ck and Wizzle, the method I use is more indicated when you are going to use the MPH intravenously, so there are barely any residues left in the solution. What you need is a some 10mL syringes, coffee filters and cotton.
    This method is called backloading. In your cases, crush the pills and use large amounts of alcohol to dissolve them. Let the insoluble inerts get to the bottom of the flask. Prepare a syringe shucking in a layer of cotton, then a layer of reasonably sized sliced coffee filters and then another layer of cotton and then re-attach the plunger pushing down the filters. Put on strenght. Remove the plunger and you'll see the filters are laying on the end of the syringe. Get another empty and sterile flask. Use another syringe to suck in the solution with few insolubles (since these will be in the bottom of the flask) and squirt this solution on the backloading syringe, put the plunger in and push down the now filtered contents into the empty flask. Do the same process over and over again until you see that there are resting a little bit of solution and the insolubles on the original flask. If the filters clog (unlikely), remove the filters and insert brand new cotton/coffee filters/cotton layers.
    Like I said this procedure is mostly used for preparing IV shots, but in the end when the alcohol evaporates you'll have the purest methylphenidate possible to snort or whatever you're going to do.
    Mind you I am suggesting ethanol because of the gelatin on the pills, with normal IRs water is much more recommended.
    I hope this guide helped in some way.
    Laterz.

    Methylphenidate is very soluble in water.
    Thats why people can snort it.

    I don't even know if its any soluble in any type of alcohol.


    Just crush the pills up.
    Put the powder in some water.
    Then filter it threw a coffee filter, and keep the liquid.
    Ditch the filter, or whatever, there would probably be a few mg's on the filter.
    Anyway, you could then just heat up the liquid in a microwave or something.
    And let it dry out into powder, then scrape out the powder and enjoy!

    That wouldn't take out the gelatin though. An alcohol extraction should.

    Will the extraction also work with the PCH generic? They contain:

    *Methylphenidate HCl
    *Calciumhydrogenphosphate
    *Lactose
    *Microcristalline cellulose
    *Corn starch

    EDIT: Tried the extraction on the Sandoz generics. For the record, they contain:
    -Methylphenidate HCl
    -Calciumphosphate
    -Lactose
    -Wheatstarch
    -Gelatin
    -Magnesium stearate
    -Talc

    Hi everyone,

    I tried the afforementioned method with denatured alcohol. (the pharmacies didn't have any IPA so i settled for this, will get IPA though). The denatured alcohol contains:
    - 96% ethanol
    - methyl ethyl keton
    - linalyl acetate

    The MET should be no problem, The solution reached probably about 80 degrees celcius so it should all be evaporated.

    The lenalyl acetate is probably still in there since it has a cooking point of 200 degrees celcius. I read that it's pretty harmless though so me and my friend sniffed some anyways and it works like a charm! It does taste kind of soapy though and I've read that the lenalyl acetate is also used in perfumes and such, so perhaps that explains the problem.

    Also, I have about 450 milligrams of powder, while I used only thirty 10 milligram pills (300 mg Mpd HCl). Could this be explained by the lenalyl acetate?

    I could evaporate the lenalyl acetate in an oven (200 degrees celcius). I am wondering though if that could be a problem since ovens aren't too accurate with their temperature and Methylphenidate HCl melts at 225 degrees celcius.

    I'll be sure to get IPA for my next extraction.

    Note: The coffee filter clogged up like a beeee-atch so I used two.

    Any input will be appreciated, also on the PCH generics. Thanks!
