    a friend told SWIM:
    by ArucardX
    "ver had the urge for a quick "jolt" with no access to any fun substances? I'm sure many have heard of the mythical Benzedrex inhaler. But wait, you have to eat a stick of cotton?! No more! Take that cotton rod and turn it into KITCHEN CRANK!



    Benzedrex cotton
    Eye dropper
    Hydrochloric acid (36% or below)
    Isoprophyl Alcohol
    Distilled Water
    Petroleum Ether--Zippo brand lighter fluid can be substituted
    Cup/bottle/beaker/flask (something to mix and shake in)
    Pyrex baking dish (something to use for evaporation


    1. Cut cotton into small pieces. Put cotton in Cup and add 3tsp Isoprophyl alcohol. Bring Distilled water to a boil

    2. Pour a generous amount of boiling water over mixture until mixture is well-diluted--the cotton should be fully submerged. Add 30 drops of Hydrochloric acid to mixture. Stir together, being sure it is well-blended. Allow mixture to sit for 15 minutes.

    3. Remove cotton from mixture, being sure to avoid contact with the skin (gloves/tongs are good) and squeeze remaining liquid from the cotton.

    4. Add 2x the volume of Petroleum Ether to the 1x volume that is your mixture and shake well. Once well-shaken, allow the mixture to settle. Notice the Ether forming a layer above the rest of the mixture. This Ether has separated the menthol from our extraction. Suck off the top layer with the Eyedropper.

    5. Pour remaining extract into evaporation dish. This can be allowed to evaporate naturally, in the oven, or in the microwave as heat doesn't not damage the final product.

    6. Scrape dry crystals from the bottom of the evaporation dish. If done correctly, your product should have an off-white, yellowish tint to it.

    Congratulations you've just made KITCHEN CRANK
    Yeah, final product is propylhexadrine."

    Great guide 0utrider!

    My hamster would also like to add that the there are some differing opinions on the amount of hydrochloric acid required, as well as on the strength. My hamster said that he has performed successful extractions of propylhexedrine using 10-20 drops of hydrochloric acid, 30% (v/v) solution. Hamster has also read that lemon juice or similar acids can be substituted if HCl is not available, but he has never tried this.

    There is also more information on extracting propylhexedrine from Benzedrex inhalers on this older thread: TEK - Propylhexedrine Chemistry & Extraction
    Its a long thread (3 pages), but still has some great info for those willing to sift through it.

    Thanks for the writeup!

    A friend of one of my friend's friends (Lets just call him swim), was talking the other day about the extraction he did himself following THIS tek... He told me that he never tried making any sort of crystals before this, so this was a new experience for him to learn. Swim used two inhalers, and maybe a little bit more ingredients here and there. He also used a big ziplok bag as a separation funnel to get the bottom layer only. He used a square glass baking dish, and set it on a cold burner and started it on LO (NOT heat setting 2 or 3, but the lowest possible). After about 30 min, the bottom of the dish was very warm-hot to touch, and the liquid was steaming gently. Here's a pic he gave me of the results:


    He said that he was stoked to snort them, but only after making the crystals, he started reading about how they burn your sinuses. They smelt like a very light, but pleasant cleaner/detergent. He gave it a tiny taste and said the stuff had a bite. Then proceeded to chop some finely and snort the smallest amount possible (since he never snorted anything or made crystals before, remember?) It burned him like hell, and he threw that idea out the window. This made him a very sad panda. The crystals fit perfectly into 4 (size #1) pill capsules, and it was very easy to take.

    However, swim used the lemon juice extraction a few time previous to this, and got the exact same results with 1% of the effort. His advice, soak in lemon for at least 2 hours, squeeze out cotton, mix with any drink you want, knock it back, take a drink of something fresh, and chew a piece of gum. Never had a problem with nausea, or burps, or anything like that.

    Swim's next thing will be making dmt from a/c, supposedly he has already jumped the gun on that, so I'll have to see how that works out for him..

    Damn those crystals look tempting to snort

    Hi, AFOAF would like to inform everyone about a super easier way to digest the Benzedrex cotton swabs, without the disgusting taste of menthol and lavender: Make it a capsule. Really easy!
    This is what AFOAF did:
    -Break the Benzedrex box and take the cotton swab out.
    -Cut it to pieces.
    -Empty a capsule (AFOAF emptied herbal diet pills. But you can also buy empty capsules in amazon as well.)
    -Stuff the empty capsule with the cotton. One box of cotton swab normally fills 3 capsules.

    And voilá! Your tasteless Benzedrex dose is ready! And it only took you less than 5 minutes!!!!

    ^^Maybe, but that doesn't get rid of the menthol lavender burps. I've done this many times using the "Stacker" pills, but I still burp for hours this disgusting taste of lavender and menthol, it's not worth it.

    Def the best way is the original post, the ingredients are cheap and one bottle of each will last you quite a while.

    Has anyone actually tried the finished product if done as directed in the original post? Does anyone know what the chemical ID of the produced compound would be or is it simply the same minus the menthol and lavender?

    Benzedrex experience.

    Whet to Walgreens in Arizona and they didn't have it.
    Went to Walmart and bought the two boxes.

    Got home around 11am. I opened the box and used a pair of pliers to open the plastic tube it comes in. Once I got the cap off I extracted the cotton inside.
    I cut the brown stuff off the cotton and cut that into two pieces.
    Used a small screwdriver to push the cotton into empty pill cases.
    This made it very easy to swallow.
    I first swallowed 150 mg to test its strength.
    About an hour later a felt a little buzz so I decided to take the rest.
    I swallowed 350 mg and ate some applesauce. About an hour went by and I thought I would never feel anything. Soon after it started kicking in and now I am typing this his review. If I ever do this again I would take two of three to get a good buzz going.

    I would have to rate this stuff a mild STim at best.

    Clever, cutting the oil portion out. I wonder if the propylhexedrine portion is as unevenly distributed as that oil.

    You shouldn't eat the cotton. That could cause problems. You can soak the cotton in a solution of citric acid, squeeze it a bunch, forget about the cotton.

    A friend reported using citric acid instead of lemon juice when soaking in water for a simple extraction. Lemon juice, we believe, contains an emulsion of oils or at least nonpolars (hence the fact that it's not transparent). He claimed that he had used lemon juice on several occasions and the initial soak had always been intense and unpleasant with the flavor of the essential oils. One day he used citric acid and dissolved an amount in water that produced a solution of similar pH to lemon juice. He told me that the resulting initial soak seemed to contain hardly any oils and was much easier to consume and didn't produce any stomach upset. He doesn't believe the solution was any less potent but he had a tolerance to the compound at the time and had used it only 2 days prior so it was difficult for him to assess. Said he'd tell me if his next experience worked using this method but that it may be a while.
