IV Talpentadol
Another update, meant only for HARM REDUCTION.
On three occasions (since my RSD has become much more erratic and less painful) I experimented with IV'ing this substance, the only logic behind it being that I knew my doctors wanted to cut down on my pain-meds, and that this was the final script. In doing this, I washed off the orange coating in distilled water, then crushed it in a sterilized spoon, and filtered it twice using multiple cottons. The product was maybe .3 mL of a clear liquid with only the faintest yellowish tint. I had a trusted friend actually do the IV, as he has a great deal of experience in that area, and after registering, everything went in smooth as could be (as though in a hospital).
Despite my reservations, I have to say that it was nearly the most enjoyable drug I have had IV (the others being generous shots of hydromorphone in the hospital, and one experience with VERY pure black tar) The rush is very gentle, not so much of a shock, and feels rather like a very large hydrocodone dose, with a moderately speedball-esque feeling, and a unique warmth which lasted about 2.5-3 hours, nodding for most of the time (dosage was around 150mg and later shots at 225mg) Also, its worth noting that one of the shots contained 5mg MDPV (pure), and that combination blew everything else away. However, this was not without some consequences.
As a warning, its probably not at all good for you to IV either drug. My friend very expertly hit and registered the vein every time, and yet I developed incredible bruises, about the size of a postage stamp per IV site, that expanded; turning from purple to shades of blue and green. For comparison, the bruising I got on the IV site for black tar,(in which I made multiple attempts to register) was slightly smaller than a tic-tac, and light purple.
As a (humorous or cautionary) aside, I was wrongfully searched and arrested two days later, for carrying my pills without all of the prescription copies

(as well as possession of an oral syringe w/out needle, for plugging). Suffice to say the bruises on my arms did not help convince the cop that I was a chronic pain patient. Luckily all charges were dropped, after 2 months of assembling paperwork.
Moral of Story: The potential costs of IV Talpentadol do not equal the benefits
