Well damn, if MScontin works for you! Than that's straight! I have never had success with it, other than IV with the morphine IR tabs, which are much easier to prep for IV and, I actually for the first time, really enjoyed morphine done that way! but orally, 500mg wont even have me nodding, the smallest little bit of "euphoria" if you want to call it that, would come on in waves for like 3-10 mins at a time, every so often when I took that much orally, with an opiate tolerance that was decent sized.. Whenever I do opioids/opiates these days, its usually via IV though.. That has now become the only way I like to do most drugs(unfortunately!), able to be done like that, except for oxycodone! That is the ONLY opioid, I take, that I would rather sniff or plug, or even smoke on foil, if they are OCs which is damn near impossible to find in the US now.. or the IRs aka roxy 30s, but I only really smoked them if I had some to sniff or plug too, because the high from smoking them is very short lived on its own, yet very powerful and hits you instantly each hit, Iv oxy is not too good though for whatever reason, it just has a faster onset than oral, sniffing, or plugging(but only slightly faster than plugging) with no real "rush" like you get with heroin, dilaudid, or opana... with those damn OP oxys thought, I will only fuck with them if I run out of my subs, which is never these days, I stick with my sub dose, and don't ever let myself run out early or anything, and haven't touched a full agonist I like 13 months or so.. just subutex. But yeah if I am desperate enough, and somehow cant find oxy IRs, dope, or other strong opioid pharms, I will take OPs, just to keep me well.. hope I never have to again, the high/feeling I get from them is lacking IMO, and compared to the OCs isn't half as strong as they used to be, pre-matrix formula, with original OxyContin OCs.. even when I took those orally, they would hit me way harder and faster than the OPs ever have done for me the same way.. orally. Consider yourself lucky if you like the feeling of oral MScontin, and actually get something decent from it.. not a lot of people do.. I know I don't!
