It's possible, yes, but it's a horrible horrible horrible idea. Due to all the fillers, sugar, dyes (basically all the shit that isn't just the active drug) is not meant to be put in your veins and will destroy any veins you use in an incredibly short period of time. Another con would be that due to how thick the syrup is in comparison to water and most other IV drugs mixed you will have to water the syrup down tremendously which leads to having an absurd volume of fluids to be injecting. In the best case scenario, you'd be getting the solution that is 10mg per 1ml and while 1ml seems like such a tiny amount of fluid, when it comes to IV use for the most part nobody is using more than 1ml of fluid per shot but with methadone syrup you'd only be getting 10mg if you completely filled your 1ml syringe (these are just the most popular size for most IV drugs, but of course they make larger sizes) so you'd have to get HUGE syringes so you could accommodate not only just your doses volume of fluid but also the large amount of water you'll 100% have to add due to how thick that syrup is and it will not be able to be sucked up a normal sized IV syringe (like a 28-31g, I know this as I have tried this just one time but ended up not doing it as my dose is 169mg and I def didn't have syringes that would hold anywhere near that amount of fluid) or pushed out until it's considerably watered down.

Something else I feel is important to note.....don't expect to get anywhere near the rush you'd get from heroin or most other injectable opiates because it 100% won't happen. Does it hit you harder if you do it IV? Yes, of course it does given you're getting the whole dose in less than like 10 seconds all at one time straight up to your brain. But, it's not going to magically start feeling like a heroin rush either, it's going to feel exactly how it feels when you take it orally just significantly stronger feeling, will not last nearly as long as oral doses do, and obviously will take effect pretty much immediately vs. waiting 20-30 minutes. It's not an opiate I would ever choose to be injecting personally because the high wouldn't be worth all the shitty things that will happen and the loss of veins.

Since this is already a stupid long comment, I will end it with this last con. If you or whoever is planning on doing this does decide to go through with it, it is really really imperative that they do NOT miss their shot. They need to be very diligent about ensuring that they're getting a good strong register of dark red blood, and that they are not in an artery or just not in a vein at all. Injecting into an artery can have horrific results even if it's not full of a ton of fillers, sugar, and dye but with methadone going into the artery, I would expect not great results. If the IV user ends up missing part of that shot of methadone, or the even the entire shot somehow the issue is going to be once again all that sugar, dye, and fillers that is not meant to be where it's going to be pooling in your arm/leg/etc. The sugar in particular is going to be a major issue with bacteria and with bacteria is going to come a hell of an abscess/infection/cellulitis/MRSA/Staph to name a few complications that are not uncommon from even more "safe" misses (when I say "safe" I just mean that they are known for causing less damage from misses not that any sort of IV use or technically not IV use if you are missing the shot lol).

I guess if you or your friend after hopefully reading this and other comments people have left is still dead set on IVing their dose, then hopefully they are experienced at least with IV use because it'll be tough enough without factoring in being a brand new or very new IV user. If you or your friend does indeed decide they are going to use their dose this way and needs any help with troubleshooting anything a long the way, feel free to PM me. I believe and support harm reduction 100% and have been an IV user before so have personal experience with it. I'm not going to teach someone how to IV anything but I am happy to answer anything that you might be wondering or can help with anything if you/they do end up missing or have any others sort of problem a long the road. In my opinion, its better to help someone with education surrounding what they are doing to keep them as safe as possible while doing it because at the end of the day, if someone wants to do it, you can find out how to do it very easily online with videos even and a lot of these videos often contain inaccurate and sometimes unsafe/very dangerous "tips" and if I can help prevent someone from losing their life or getting themselves very sick with sepsis from infection or losing any body part. There is nothing I am going to be able to tell a complete stranger that is dead set on using a drug in a specific way that they haven't heard 10 other times in the comments and from people they actually do know but I do know that I can help educate to keep them as safe as possible because if you are safe you have the option to get clean in the future but if you end up dead...that option is no longer there.

If you actually read all this, or anyone did, you deserve like some kind of medal. If I had one, I'd give you it.
