Make a liquid preparation.
I suggest a liquid preparation.
You will need:
1) Suboxone tablets
2) Oral medicine syringe
3) Small glass resealable bottle (essential oil bottles work well)
4) distilled water
5) Alcohol (the kind used in liquid medicine preparations)
6) best filter you can find (syringe micron is best, followed by lab micron, cotton in the syringe...)
Step 1:
Crush up your desired amount of Suboxone tablets, I suggest a weeks worth of doses at a time, so for you @ 4mg a day that would be 28mg or 3 and a half 8mg tablets.
Using the oral syringe, carefully measure out an amount of distilled water*
*The amount of water you use is up to you, I suggest making a preparation so that each ml contains one daily dose but remember you will be adding alcohol later, so for you that would be 6 ml of water into 28mg Suboxone leaving you with 4mg buprenorphine per ml solution after the 1ml alcohol is added later, bringing you to 7ml water.*
The only problem is that this may not be enough water for all that powder, if that's the case, then you can use 13ml water (14ml-the 1ml for alcohol).
Step 2:
Lets assume you use 13ml. After heating the distilled water so that its "hot" to the touch, mix the powder and 13ml of water (measured accurately with the syringe) in a shot glass or something similar. Mix until it looks like its completely dissolved, and let cool to room temperature, then put it in the fridge for half an hour.
Step 3:
Take the solution out of the fridge and stir it a little. Now its time to filter. If you have a micron syringe wheel filter that's the best but really its overkill. What I did is backload some cotton into the syringe, use the plunger to cram it down towards the tip, and draw up some water and squirt it back out to wet and "wash" the cotton. After this, draw up your solution through the cotton and then carefully remove the plunger and pour the filtered solution into a new glass. Most oral syringes are 10ml so this will take 2 runs, you can use the same cotton.
Step 4:
Now that you have all your filtered solution in the new glass, its time to add the alcohol. You don't need a lot, for 13 ml water add 1ml so you are even with 14ml liquid in the end. If at this point you have lost some water in the filtration process, add enough alcohol to bring the total liquid up to 14ml exactly. The alcohol is to increase absorption and preserve the solution, so its not crucial but it does help. So anyways add the alcohol and remeasure your liquid to make sure your pretty close to 14ml (13.5-14.5 is OK).
Step 5:
Ok, so now you have a 14ml solution containing 2mg Suboxone per ml. This means every day you suck up 2ml with the syringe and squirt it under your tongue, and hold it there long enough to be absorbed (5 minutes should be plenty). This will last you a week, if the process is too time consuming, you can make bigger batches, the reason I do a week at a time is because I read somewhere that when a drug is in a liquid preparation it can sometimes lose potency faster than when in tablet form, but idk about buprenorphine. TO minimize this loss, I always store my solution in the fridge, this also inhibits bacterial growth.
POTENCY:
The potency of this solution can be upped by using less liquid. To find the most concentrated you can make it, you would need to look up the solubility of buprenorphine at room temp, it probably pretty good so you can make a highly concentrated solution, maybe 8mg per ml, but I am unsure.
This liquid solution is more powerful than the tablet form. This was proven in a study where a liquid preparation of Suboxone was used in the study and afterwords it was found that the liquid preparation was better absorbed sub-lingualy than the tablet, likely due to the alcohol and less powder, that is why I suggested it to you, it should be as powerful as nasal or rectal administration if not more.
NOTES:
This process can be improved upon, if interested you (anyone) can look up the solubility of buprenorphine, how the solubility is affected by the other compounds in the tablets and the alcohol, and if a solution of buprenorphine, water, and alcohol will last for a long time. Also I need to know what kind of alcohol is used in medicine like cough syrups. You can then either post the updates or better yet PM them to me and I will edit my post, giving credit to whoever looked up the info of course.
Warnings!
You could possibly be working with a highly flammable alcohol solution, I'm talking about the alcohol itself as the finished solution will not be flammable but if you are working with alcohol above 50% concentrated, you need to be careful with it around flames, as the vapors and liquid can both ignite. This is easy just use common sense, like don't keep an open container of 90% concentration alcohol next to the stove when you heat the water. To be extra safe use an electric stove designed for laboratory use.
