Hi everyone, this is my first post on Bluelight after a couple of years of interest for this nice and useful forum. I apologize in advance as my english can be a little strange sometimes.
I recently came across a Transtec patch 35mcg/h, for a total of 20mg buprenorphine. I let it sit in a pot for four days (a lot of time, i know, but i wanted to be sure) with roughly 15 ml of 90% ethanol. I then recovered 10 ml of a 2mg/ml solution.
Initially i didn't intended to IV it, i was thinking more of sublingual administration as i was worried about the presence in the solution of glue or similar products (although it looks perfectly clear), but as a former IV heroin addict and given my love for needles, i ended up ignoring my plans of being a little smart. So basically I:
- suck up 3 units of the solution (more or less 0,5mg of bupe: i have a very very low tolerance as i'm managing to be a weekend user)
- place them on a spoon and gently heat it from below with an hair dryer until all the liquid evaporates
- add some water and stir a little
- suck the solution in a syringe through a Sterifilt filter
The filter definitely retains some dark stuff and the solution, although not crystal clear, seems fine. My hope is that the glue or whatever is soluble in ethanol but not in water: obviously the main scientific reason behind this theory is that i WANT to use needles
. Effects are as expected.
I wanted to ask you if you think that i'm doing something too dangerous, given the list of excpients:
- Adhesive matrix (containing buprenorphine): [(Z)-octadec-9-en-1-yl] oleate, povidone K90, 4-oxopentanic acid, poly[acrylic acid-co-butylacrylate-co-(2-ethylhexyl)acrylate-co-vinylacetate] (5:15:75:5), cross-linked
- Adhesive matrix (without buprenorphine): poly[acrylic acid-co-butylacrylate-co-(2-ethylhexyl)acrylate-co-vinylacetate] (5:15:75:5), not cross-linked
- Separating foil between the adhesive matrices with and without buprenorphine: poly(ethyleneterephthalate) - foil
- Backing layer: poly(ethyleneterephthalate) – tissue
- Release liner (on the front covering the adhesive matrix containing buprenorphine): poly(ethyleneterephthalate) – foil, siliconised, coated on one side with aluminium
I don't particularly like to IV buprenorphine (cold and metallic in my opinion) and furthermore there is no real rush, so i might think of plugging. Does anyone have any experience with rectal bupe, especially in terms of 'niceness' of effects? A pro would probably be less nausea, but i like the shortened duration of IV administration. And of course i still have a needle fixation...
Also, how long is my solution supposed to 'keep'? Not in terms of bacteria but for a possible degradation of buorenorphine.
Thanks in advance.
