So was skimming through the radio stations and came across one that had a guy talking about this and that, decided to write down what he said, here's a little bit of it...
Ahh god, just said he wasn't coming back into the speed forums but ya lol. Thinks this could be of some use to people that are willing to take the extra step to take a product that won't taste like shit. This TEK yields a nearly pure product.
Most TEK's call for the use of HCl which is completely unnecessary and actually a little unsafe for those that don't know how to properly handle such a strong acid. This TEK will used distilled vinegar which is much safer if accidentally handled improperly. But it does call for solvents which should be handled and stored correctly, although are considerably safer than strong acids.
Benzedrex Inhaler (Containing 250mg Propylhexedrine Freebase)
Distilled Vinegar (5% acetic acid)
Non-polar solvent (the following will work: Naptha, Toluene, Xylene, DCM)
1-2 Mason Jars
Separatory Funnel or Glass Dropper and alot of patience
Well the Benzedrex Inhalers contain both menthol and lavender oil as inactive ingredients along with the freebase propylhexedrine. (Freebase Propylhexedrine = FP) Take the little inhaler and use a pliers to pull off the nose piece, this is done to obtain the cotton inside that holds the FP.
Now place the cotton in the mason jar and add 100ml of distilled vinegar (5% acetic acid) swirling it around occasionally for 30-45mins. Letting the freebase sit/shake for awhile will help give it time to convert to the acetate form, 5-10mins would probably be insufficient. Now pour the distilled vinegar through a funnel with a coffee filter in it, either into another mason jar or a sep funnel. Do another extraction the same as before, less time such as 20-30mins and less distilled vinegar such as 50-75mls is OK on the second extraction. Pour this through the filter funnel into the jar or the sep funnel.
Separatory funnel will make this a whole lot easier as the next step involves washing the vinegar/propylhexedrine acetate with a non-polar solvent to help rid it of the other oils. But it can be done with a mason jar and then use a glass dropper to suck it off but just takes time and patience.
This next step is necessary as you can actually see the oils floating on the vinegar extracts and would just end up in the final evaporated product.
Pour 100ml of non-polar solvent into either the sep funnel or jar. (Lets use sep funnel as the example as thats what was used in the original experiment, Naptha was also the solvent used during this step but any mentioned above will work just fine or maybe better.) Shake the sep funnel around for 5 minutes, there is really no need to worry about any emulsions forming. Let sit to separate for 5 minutes and then drain off the vinegar/propylhexedrine acetate solution into an evaporation dish and set in front of a fan.
For those that are using the mason jar method, do same as above but then instead of draining off the bottom layer, you will have to slowly suck off the top layer with a glass dropper. Its likely you wont get it all, you have the choice of doing the nonpolar wash one more time to get out almost all of it, or just leaving a little bit and possibly tasting lavender oil/menthol in the final product. Even if you just leave it with one wash, the taste of the end product will be infinitely better than if it were consumed as is in the inhaler.
After all the water and acetic acid of the vinegar has evaporated there should be left propylhexedrine acetate in a rather pure form. It can either be scraped up, or redissolved in water and consume. Will post up pics some day but not any time soon probably.
For nice crystals redissolve in distilled water and pour into a glass with a flat bottom for easy scraping, or maybe a pyrex bowl. Then let it slowly evaporate over the course of a week or two in a warm environment that gets indirect light most of the day, the indirect light will help avoid mold forming.
He plans on further refining this process to one day include a fast and easy recrystallization step he hopes from something like denatured ethanol or similar solvent.
The product was almost fully evaporated there was a very small amount of vinegar left, there was obvious crystal formation along with white areas that would probably be powdery when scraped up. It was redissolved in a cup or so of water, using his finger to make sure it all redissolved into the water.
This experiment wasn't actually for him but more for his girl to see if this was a suitable substance for helping her in times of heavy studying for college courses. So it was her that consumed the substance, and all further notes will be from a second hand point of view.
He did taste it before he gave it to her to see what it tasted like. There was a slight acidicness from the slight bit of vinegar left, but mostly a bitter flavor that tasted like a drug he can't quite put his finger on, maybe some type of amphetamine.
She drank the cup, and was disgusted by the bitter flavor along with the vinegar flavor. Swims friend kept very good eye on her to notice even the most subtle of changes.
For the first hour she didn't seem to change much, but by the end of that hour her eyes widened and she began to talk much more eloquently than usual. Never heard her use the english language the way she did. Although she seemed to get anxious moreso than usual around his family which is unusual for her. She commented that this substance would definitely work well in helping her study if need be. She seemed pretty sped out yet relaxed and content for about 3 hours, then she smoked some sativa strain cannabis and got slight anxiety for the next 2-3 hours.
Once the slight anxiety hit from the cannabis she noted that this dose was probably too high and that half of that would be good for studying. After a massage and smoking some resin (seems to be more relaxing high) she calmed down. Sex also really seemed to help.
She took a sleep pill that contains melatonin, valerian root, passion flower extract, and chamomile which usually knocks both her and him out cold within 30-40mins. She seemed restless and was still getting up and asking for cannabis cookies and resin 2-3 hours after taking the pill, showing that it was still effecting her. This was 7-8 hours after dosing mind you. Full effects seemed to last about 9-10 hours before she finally was able to sleep. Normally all the cannabis cookies, sleeping pills and such would have knocked her the fuck out, showing that this stimulant is for real.
The only thing she didn't seem to like about it was the edgyness she got from it 3 or so hours in but that was mostly likely because of the combination of the propylhexedrine acetate and cannabis sativa that induced the anxiety. Lower dosage next time for her will definitely work well, she only needs 10mg or so of adderall to help her study well. If anybody could suggest a dosage equal to 10mg of insufflated adderall that would be great, she will most likely snort it next time as well.
This substance definitely has its uses, and really hope this extraction technique hasn't been posted before. If so please delete this thread. Also wasn't sure if this should go into phenethylamine or not, from what swims friend read this drug isn't even a phenethlyamine but a cycloakylamine or something probably just butchered that.
Really tired, just wrote this super late or early whatever you prefer, so there may be typos and errors, he will edit tomorrow.
This was an excellent post and quite informative as I am experimenting with methods of purifying this product. I'd like to get something akin to a crystal methamphetamine like substance if I can. I have noticed my final product will melt down into a lovely liquid when heated with a torch lighter set to a low flame. I havent tried to smoke it yet as I am not confident of the safety of doing such. I'm more of a snorter but I'm a bit of a glutton with powder and could easily over do it. If you try any other methods or tweaks I would certainly love to hear about them.
then she smoked some sativa strain cannabis and got slight anxiety for the next 2-3 hours... Once the slight anxiety hit from the cannabis she noted that this dose was probably too high and that half of that would be good for studying.
What?!?! Grumble, grumble. Pot-heads- always judging things by how well they goes with weed.
Lol yup, if one smokes multiple times daily (as is the case with the participant in this experiment) then it would be a good idea for the drugs and dosages of those substances to be in line with what that person wants or needs. Of course someone that doesn't smoke (different buds different highs, indica might be better) might find a higher dosage more tolerable, thats for the person reading to figure out for themselves.
Nothing really, thats a completely viable method. But that limits the user to just oral consumption, with the above tek one could get nearly pure propylhexedrine which could then be taken a number a different ways. Also the above method makes sure all of the added oils (like camphor) gets stripped away, while the lemon juice method you describe will most certainly have some of those oils floating on the surface. Plus the above TEK doesn't take very long so its not a super tedious process, and could be scaled up with as much as you wanted and then the pure product could be stored safely for later.
They both work but its all about the factors that play into making it, if you got the time and supplies then make the pure stuff, if you got 15mins and need it in you 15mins ago, then probably gonna wanna do the quick and easy process.
To Finity, although he is banned. Purity of any substance should be of utmost importance, like said in the last few posts, those methods you describe leave behind alot of unwanted oils found in the inhalers that will probably make you feel shitty, or at least give more negative side effects than the pure product. Doesn't matter the route of ingestion. Nuff said...
And to MrIrishMan, acetone would not work as it is miscible with water, in other words when you pour in the acetone to strip off the other unwanted oils, the acetone is just going to mix with the water instead of separating into two layers. The following will probably/possibly work; toluene, xylene, naptha (petroleum ether), ether, chloroform, heptane, hexane, kerosene, DCM. Some of these can be found at local hardware stores, sometimes labeled as the chemical itself and sometimes labeled as paint thinners and such. Have seen certain solvents in art supply stores too but its a bit of a long shot.
