Harm Reduction Micron Filtering Mega Thread and FAQ

ok I have a predicament. I used to be able to filter 64mg of suboxone film through one single whatman GD/X 0.2um PVDF media, 25mm, etc.
just earlier I was trying to filter 60mg suboxone into 30ml, so I could get 2mg/ml. when I pushed through the first filter, hardly any of the liquid would pass through whether I used soft or strong pressure. so I took that one off and added another filter, and the second one could hardly pass any of the liquid as well.

from there I used a separate 3ml syringe to remove air from the vial to reduce air pressure. then with the 20ml syringe, I pulled back around 5ml and pushed through both filters again.

it seemed like I had less pressure trying to put it back in the bacteriostatic vial, but still, after I've done all the recommended steps, my vial still looks basically clear. I remember back when I used to micron my old batches, the liquid in the vial was at least semi-orange.

I'm wondering if I over-pressured or over-pressured my vial, or any other reason why I could hardly push even 1-5ml of water through each micron filter.

I'm really hoping I'm just worried for no reason. I've done this before and it works wonders, but if I just wasted 60mg of suboxone for no reason, I need a little bit more schooling on how this is one.

If anyone knows whats going on, please let me know. If I failed and none of the product went through, I'm going to be pretty fucked come the beginning of feb
 
How to micron filter - a video instead of pictures and words.

Enjoy!

I was going to make a video myself doing this but I figure this way I don't have to.

I think you're fine. Are you cotton filtering first?

When drawing water out of a vial you want to inject a similar volume of air into it, to keep an equal pressure inside/outside the vial.

I'm not sure what else to say though - if you're feeling the effects I'd say you're doing it just fine.
 
What about methadone? I know, probably not smart. What will I need to shoot some(2.5 or 5mg?) Thanks
 
I don't have a good answer for you but no not smart.
You would need the same supplies you would need for shooting any pill.
Micron filters, syringes, etc.

I do have to ask what is your reasoning in attempting to do this?
I myself use IV opiates & also methadone but have had no reason to IV methadone.
What do you hope to gain by doing so?
As far as I'm aware there's no rush & no real gain's in bio-availability.
Basically no real benefits to injection vs oral route.
As such I'm curious as to why you would wish to take the risks involved without a reward.

Other than that the instructions posted in this thread regarding micron filtering apply.
 
Thanks IndustrialStrength. I was just curious. Ive done my homework on methadone and totally agree, its NOT worth it. Methadone just doesnt work like that. I take my 40mg a day orally and just leave it at that. I'm still in a lot of pain but I rekon I have to live with it till I see my pain Dr in 2 months. Wish me luck and thanks for the reply!!
 
Glad to hear my response was helpful & helped to avert needless risk & potential problems.
I'm sorry to hear that your still in a lot of pain & hope that you can get that taken care of.
Best of luck! :)
 
Some questions about micron syringe filters.

Hey, I use them for mscontin. The first kind I ever tried were PTFE, these were totally impossible to use, although I heard if you run alcohol through em first then water based solutions will flow.


After that failure, I got a great deal on 100 NYLON 0.22 micron filters off ebay. I noticed the original post said that nylon is no good for water based solutions. These actually work fine for me, but they clog up after about 5mL, less if it was really cloudy (I prefilter through cigarette filter before). It takes a decent amount of pressure in my 10mL glass syringe (luer lock) to push it through, but drop by drop it works. The final product is definitely being filtered correctly (turns cloudy to crystal clear).


Also, I've had good experience with the NYLON off ebay, they are sometimes DAMNED CHEAP noname brands. But only 3 out of 100 were defective.

I am totally surprised that with the filters you are using you can push hundreds of mL. Perhaps I should switch over.
Also does anyone know if 0.45 micron is fine enough to remove the talc from mscontin? My regular ebay supplier is out of 0.22 this time.

Thanks guys. Glad I found this thread, but would like some feedback about my NYLON filters.

EDIT: I just found this: http://catalog2.corning.com/lifesciences/media/pdf/t_filterselectionguide.pdf
It seems to imply that the only filter not good for water solutions is the PTFE:

Sterilization and Ultracleaning 0.20 to 0.22 All membranes except PTFE of Aqueous Solutions

So perhaps the NYLON is ok. I am also looking into this MCE type membrane syringe filter. It looks like it should do the job and can be had quiite cheaply. If I get them I'll be sure to let everyone know.

EDIT: oh just FYI, I almost never IV, always subcutaneously inject. Usually make 4mL out of 120mg mscontin (2 orange Mallie 60mg pills). Maybe wash one more mL, or just eat the leavings on my spoon. You get a bump from the liquid and the histamine reaction, but the micron filtering is great. Never had an absence. Knock on wood. I had a scary one from trying to shoot OP40 oxy, I did the grind,microwave,freeze,grind technique. THEN cooked it up and put it through a 0.22 micron filter. The end product was still very stringy like saliva strands, whatever that polymer is, it does not come out in the filter. Had nasty absense which came to a head. I actually used a larger gauge syringe to drain it a few times though. Had muddy looking fluid in it the next week, scary shiat.

Thanks for letting us know the PTFE ones were fail! That'll be a good reference point for the community.

I'm glad to hear nylon ones work for you! Thanks for the subjective report. %)
 
Harm Reduction at its Finest

I realize sourcing drugs is against the rules entirely, however, sourcing micron filtering supplies, as well as harm reduction supplies is OK.

Once upon a time while I was still a moderator for Other Drugs, I asked Phrozen (while he was still an admin of Other Drugs and Bluelight in general...) if it's OK for me to sell micron filtering products to Bluelighters through Bluelight.

Since I never got an answer I'm assuming it is. If I make a considerable profit margin in 2012 (I don't expect to honestly) - I will be donating some of it to Homeless Healthcare Los Angeles.

Send me your email address asking for the Captain's micron filtering menu to my inbox and I'll email you the menu.

The Captain's menu contains....

planning to implement the micron filtering

Wise decision, excellent item for reducing impurities.
Google "Harm reduction by syringe filters: A cost-effective means of improving the health of injecting drug users" by McLean and Bruno
Informative article, not too long, mostly about pills but the theories hold true for IV administration of anything with questionable sterility...

Just how much water would be a reasonable amount for a 1g of amphetamine? I'm now struggling to find a proper ratio.
Click to expand...

If you are talking about 1 gram of pure amphetamine, you'll need approx 9cc of water at room temp, minimum.
This is the max solubility of Amphetamine, (8.8 according to Merck). [1]
Most common cutters (used in my area) will be more soluble than that in water, so if using diluted/impure gear you may get away with less.

What's the most convenient process of getting the solution from vial to insulin syringe
Click to expand...

Have you considered a drawing up needle? They're blunt, usually somewhere around 40mm long. Common in gauges around 18-19.


[1] No comment is made in the Merck reference regarding what salt of amphetamine (if any) was used when determining this figure.
I have been able to find reliable sources claiming Amphet solubillity as either 1:8.8, or 1:9, but none specifically describing solubility of the salt compounds, ( Amp Sulfate & Phosphate, Meth HCl etc).



Cheers,

There are different gauges for drawing solution into a syringe; my preference is 23G. :)
 
This may have been asked and I just used to wrong search terms:

Can I use filter paper instead of dedicated syringe filters?

Harm reduction works better when it's cost efficient:

1. Cut over-sized piece of filter paper.
2. Coat edges of [needless] syringe with food grade silicone.
3. Place paper over the silicone-covered end of the syringe and apply even pressure until it's cured (few minutes).
4. Optional, secure filter edges to syringe. Coat the 1/2" of the barrel closest to the paper with the same silicone and bring the edges of the filter paper up to meet them. A smooth fit may require making perpendicular cuts and overlapping the paper around the barrel. (This should add resistance to the pressure generated during filtration).

It's hacky, but will it work?
 
Oh, of course. Let's assume it's the standard 0.2um.

I think I remember reading that syringe filters have a few layers of filter? What is the likelihood that they produce sheets of filter paper then cut some to size, stack and adhere them to the plastic housing that makes up a syringe filter?
 
How necessary is it to buy sterile filters, compared to factory sealed ones without the sterility label?

Realistic use is affected by cost.

Considering cotton is often the alternative and cotton fever is not rampant, I'm wondering how much of a compromise fresh, non-sterile filters would be.

edit/add: How helpful would the addition of benzyl alcohol be in hedging against a non-sterile filter? (Obviously this is subjective but please, opine away!)
 
How necessary is it for something to be sterile before you shoot it up in your veins?? I'd say it's pretty fucking necessary. You can't put a price on your health.
 
I don't use drugs intravenously.. But I need to remove the fillers and binders from my adderall so I have a pure amphet to sniff.. is this what I need to so the extrcation
 
So i have my solution prepared in a vial and i want to use it (this is hypothetical, i haven't tried filtering yet). I use a large(ish) gauge syringe to draw my desired dosage from the vial and than what? i backload an insulin syringe using the drawing syringe? or i guess i could use syringe's with interchangeable tips but that would get expensive very quickly (as you'd have to use a new tip to draw, a new tip to inject and a new barrel everytime you wanted to get off)
