Hey,

I tried searching, but found limited non-consistent info about shooting up MS Contin (Contalgen) = [Morphine sulfate Pills],

I recently acquired some MS contin 200mg tabs, and wanted to get some info about the best way to get the most out of each pill when preparing them for IV use,

Im mainly experienced in shooting heroin & oxycodone for the most part, this is the first time Ive found a reliable and cheap Contalgen/ MS Contin supply,
and wanted to give it a try.

I just wanted to check in, and see if someone could provide me with some solid tips & info on shooting up these pills,
I know they are extended release and from my initial test, they seem to gel up quite a bit when mixed with water and was quite hard to filter them through a wheel filter.
When I heated up the solution with a lighter, -the liquid became clear and was far easier to draw up through a wheel filter,

My Contalgen connect recommended heating up the powder.
Even though Ive always heard heating opiates is a good way to lose potency - especially oxycodone/ oxycontin. I assume the same goes for morphine (ie. MS Contin)?


Anyone have any experience with shooting up MS Contin / Contalgen? Who could shine some light on the matter?

Now what Im wondering is; if possible is it always better to try to filter them with a wheel filter and shooting up without having to heat the liquid?
 
I use the generic ms contin 30's you get in Canada. Been shooting up those and 60's since about 2010.

By the way you can only fit 60mg's of morphine suphate in 1cc of water. Shooting a whole 200 is such a waste

Ok good to know, Ive been using 5ml Rigs, which should cover 200mg, right?

whats your process of preparing the shot?
Do you heat them up at all?
 
Mscontin is abuse proof there is no point trying to shoot them. You will be unsatisfied even if you manage to get it in the syringe

The ones in Canada can be beaten. What i do is heat the water, add the ms and stir, heat again then stir some more and add a little more water and let it sit for a few mins, then i heat the water again and scrape the gell off. Filter through a micron filter and your good to go

Dont slam 200mg's of ms ffs unless you have a huge tolerance
 
This is a really bad idea. When you apply heat you're simply letting some of the stuff you don't want get past any type of filtering you're attempting to do and destroying the morphine.

What I suggest is you switch from IV use to rectal administration. It won't have the IV quick onset but it'll be close (within 10-15 minutes). Then you can let the crushed pill sit in cold-room temp. water for as long as you want and don't have to worry about it ruining your veins or losing the material you're working with. Rectal administration is much safer, nearly as fast and provides good BA compared to oral dosing with morphine.

Although I've never attempted it with branded MS Contin before it should be similar to what I was doing with Kadian back in the day. Which was morphine sulfate time release. Except the morphine was contained in tiny time release beads inside of capsules. I'd pour the tiny capsules into a shot glass, crush, add 1ml of water, wait about an hour then plug the water containing the morphine. Then I'd add more water and drink what was left over in the shot glass so I wouldn't waste anything.

I know trying to talk people out of using the needle that are already accustomed to it usually doesn't get good results. But I thought I'd try at least. Shooting any type of pharma opioid (excluding things like dilaudid IR) isn't the best idea. Even the dilaudids have tons of binders and stuff in them that you don't want getting to your heart/veins/lungs. Seen plenty of people ruin their health over the years shooting up various pharma opioids even the non-"abuse proof" ones. Most everyone I know that did it regularly met an early grave in their 20s.
 
Yeah I’m going to second Marvin here and say that the key to getting rid of the gel is the rate at which the gel cools versus the water bonded morphine. I had success on one occasion beating the gel by pouring the hot morphine water down the sides of a freezer cold Pyrex measuring cup. Fridge would probably be better because Pyrex shatters when going to temperature extremes. Anyways run it down the sides of that cold vessel and the gel will coagulate but some water is left over that should contain morphine. Idk tho we’re all basically in the shoot / boot it and if it hits then science objective achievement unlocked.

With beating any of these types of Antabuse techs it always seems like time is on your side. Like if you put the heated water into the fridge and wait does the gel coagulate faster than the water that kind of thing.

Yeah I second this. I boofed my morphine’s that would gel up but only after I separated the gel from the water by the cold glass drip and the freezer trick I mentioned earlier. I don’t remember which way worked tho and iM sorry for that. I tried a lot of methods but basically all of them worked. I just remember the best shot being the one where I got the gel to form a ring around the measuring cup I used and left water at the bottom

Just successfully slammed 200mg's, - I have a huge tolerance, Im used to shooting up 320mg of OxyContin.

I heated the crushed MSContin, water solution as little as possible. Until I had a somewhat uniform solution, filter with a micron wheel filter, -which was a very slow process, but worked out in the end. Probably wont be going through all that trouble again.
 
Why are you IVing oxycodone? Everyone I know that IVed opioids said it wasn't worth it at all. They said it provided no real rush compared to oral dosing. It was just like taking it orally only it came on instantly instead of having a short delay. Oxycodone is already high BA orally (80+%). Everyone I knew that shot dope said they didn't IV it because they wanted to save their veins for things that were worth main lining (hydromorphone, morphine, heroin and others). Out of all the pharma opioids oxycodone is the one where IVing makes the least sense.

Now I personally had a years long habit snorting oxycodone even though it was slightly wasteful. I understand having a fetish for the whole routine. But if I were going to switch to the needle oxycodone would be my last choice of opioid. The guy I knew that loved the needle the most wouldn't bother with it at all and that guy would slam anything down his veins.

Yea I hear you, I quite enjoy them via IV tbh, that's all and I feel I get more out of them this way compared to the oral route.

I guess you could call it a needle fetish, but Ive had zero complications with IV oxycodone, - I always follow strict harm reduction method,
Clean rigs, sterile water, micron wheel filters etc.
 
By the way you can only fit 60mg's of morphine suphate in 1cc of water. Shooting a whole 200 is such a waste

By the judicious use of a pH buffer, you get solubility up to something like 98mg/mL.


I think this is because the solution is SLIGHTLY alkali but not sufficiently so to freebase the morphine sulphate.

But whacking up pills is a bad plan. I'm informed that shoving the solution up your bum is pretty fast acting. I mean, M doesn't cross the BBB as fast anyway so I don't know what advantages using a pin would confir.

I read and interesting study in which H users were essentially offered two solutions, one of H, 'tother of M and to my surprise, rather than subjective effect, lower potency was the first thing noted. It wasn't a well designed study but I suppose being told one is H solution, the other is M solution would make users happy enough and since they could take as much as they wanted, did so, one assumes. They all stopped once whatever sought effects became manifest.

Interesting, so I assume the simplest way to go about this would be to use citric acid or ascorbic acid, until the desired pH levels are obtained, measured by using simple pH test strips.
 
No. Sodium acetate is cheap and to DIY it would be acetic acid and drain cleaner (NaOH), not a great plan, especially if one is errr.... 'subjectively modified' by other things.
 
Here in the UK when I use MSContin or another slow release morphine, oxy or stim I never heat them up as it can cause it to gel which can block the micron filter, the needle and obviously cause problems in the vein.

I read a research paper saying all the morphine is dissolved after 1 minute of cold stirring.

Around 65mg of morphine sulphate wil dssolve in pure water, not sure how much in tap water.
 
I believe a later work got solubility of MS up to 103mg/mL @ STP, it's firmly in the realms of scaled production of ampoules. If simple as 1.0 Mol sodium acetate, it's facile.

I did look and I can only presume someone intended to get over 100mg/mL as a possible new dose format, but while a interesting, it isn't facile. Still, if 98mg/mL means people aren't ending up using blue-tops and attached bits and bobs, I suggest it is a possible HR asset although whacking up pills has the issue of soluble excipients ending up in the mix so one may need to isolate the MS first.
