I just tried the method from the OP, but I felt nodda from it, except maybe my head playin tricks on me. This is what I did.
Used 70% iso in a pyrex bowl. Roughly 100cc's. I used a pricara duragesic poly-matrix patch rated at 50mcg/hr with 8.4mg's of fent. I placed 1/4 of the patch in the iso pyrex bowl (2.1 mg's of fent roughly if the fent is distributed evenly throughout the patch). Let the patch soak for about 10 mins then rubbed the sticky adhesive off the backing. I also placed that adhesive between my cheek and gum just in case there was any fent within (waste not want not). I then had a pot with water, about 2-3 cups, that i had boiling and started the process of evap'in the iso/patch solution. about 30/40 mins later i had an empty pyrex bowl with just a curled up patch and what looked like a thin almost nonexistant film.
Here is where i deviated slightly from your instructions, I took the pyrex bowl and removed the patch, used 4ccs of water and sprayed the patch thoroughly so the liquid washed the patch and landed in the pyrex bowl. I then used my plunger and stirred the bottom of the pyrex bowl to mix up the film into the water.
I filtered said solution and got around 3 n a half cc's back. I started by doing 10 units and leaving the needle in place for a few seconds then continuing with more. I did all 3 and a half cc's and still don't feel a thing. I took the patch and placed it in between my cheek and gum also and still haven't felt anything.
Here's my Questions.
Should I have used alcohol with water to mix up the film after the evaporation process? It sounded like that alcohol was used to store the rest of the solution to keep it from getting bacteria, and I figured i'd use it rather quickly so I didn't think i needed it.
Also, I have a pretty high tolerance to oxycons, I can shoot up 2 n 1/2 80mg OC's and just barely get a rush for about 2 to 5 seconds (if im lucky) and no nodding afterwards.
Is it safe to say there was roughly 2.1mg's of fent in a quarter of that patch? I thought normally a 50mcg/hr patch had 3.6mg's inside it, but the patch clearly states on it that it has 8.4 mg's total. I remember the last time i had a patch it was a 100mcg/hr and it had 7.2mg's in it. Either way the more the merrier, just wondering really if the patch is distributed equally or the 1/4 i have may have had absolutely nothing or just a little bit on it?
And one last question, based on my tolerance of oxycons, would you say that the 1/4 patch iv'd should have atleast gave me nods or put me out for the count? it's been about a half hour now since i did it and i feel nothing at all except maybe just a little sleepiness, but that could be because it's 2:30am where i am and well past my bedtime.
Thank you for the input, and sorry for taking up so much space.
