OK , the poster is dumb for directing it at phreex yes, but you all are ignorant for not answering a legitimate question along with your flame, so ill help you.
You are losing potency because of a few factors, one, you are probably using slightly alkaline water, add a SLIGHT BIT of citric acid (from a health food store) to the water and it will cause all the salt of propoxyphene to disolve. Remember you must have the soluble HCL not the Napsylate as it isnt soluble in water.
The next thing is you are using a coffe filter to filter it, and you shouldnt be, what you can do if it has just tylenol in it or some other crap, is put the solution in a pretty narrow but short cup and put it in a freezer, let it almost freeze (turn down the temp and cover the container) and it should crash out the bad shit to the bottom, if not in a few minutes it will eventually, ive done it a lot.
Once it crashes out, you can use a syringe to draw the water off the top without disturbing the shit on the bottom, if you cant do that, SLOWLY tip the cup so the crap remains at the lowest point in the cup, and let the water pour off into another glass, if you want to you can evaporate this to get less water so you can inject it (Assuming you used a lot), then disolve and use a cotton to filter it into your syringe and bang it.
If you are using the darvs i dont know exactly how you proceed but thats the best cold water method, BUT i suggest using the following method,
get a small vial like the little glass ones with the caps, use a specific amount of water that will fit in the syringe if you have 3ml syringes, close the cap and let it get almost frozen in the freezer.
From here drop in the powder while the water is still cold, let it almost freeze in the freezer for a while shaking it every 10 minutes or so, then eventually shake like crazy and while its still cold, pour into a large metal spoon, filter it with a rolled up piece of cotton into a syringe and it should be clear, and you can inject it. If you only have 1/2cc syringes you can evaporate it and then re disolve like heroin would be disolved, and draw in the syringe and bang it.
UNLESS you can do this PERFECT, dont do it the first time you extract, you can swallow your extract and be happy you removed the evil apap, get good at the extract before you bang it.
