[Erowid Note: IV injection of crushed pills/tablets can be very dangerous due to unknown binders and fillers present in the tablets.]
I've been an opiate addict for years and (of coarse) my preferred delivery system is injection. I got one of these orange octagons so like every thing else, I shot it. I experienced instant withdrawal symptoms (diahrea, nausea). My whole body went tingly and I experienced extreme vertigo. I later found out that there is another drug in this pill which is an opiate inhibitor. I have yet to take as directed so it may be very good. Just my 2 cents.
