If you have not already done this you should completely reconsider what you are getting into and asking. I knew people IV'ing mephedrone back in the day, I will say I have more respect for Heroin addicts. I'm not saying that too be rude but you are disrespecting yourself and the community here at bluelight by asking this. There is a fine line between harm reduction and plain recklessness, reckless threads should be closed quickly just like sourcing threads, all this does is gives others the idea which is not harm reduction and is not ok.
IV'ing mephedrone has nothing whatsoever to do with IVing DOC except the ROA which is inherently neither good or bad. I've seen people be absolute monsters while snorting cocaine, using your logic people snorting DPT are absolute garbage and disrespecting the community.
I don't see much recklessness about what this thread about. It's about discussing an idea regarding the benefits & difference of it. This is exactly what bluelight is all about. By knowing differences, risks, and what to expect you are practicing harm reduction. For fucks sake, have you ever even looked at Other Drugs? There are open Heroin addicts that post here, It's good to know what you think about our fellow members.
As for the topic of IVing DOC, you are pretty ballsy Sherminator2, but the idea is very novel. I personally would not IV, but stick to IM, whenever I have IV'd a psychedelic it's been just a bit ridiculous, one second you are sober the next you are just
gone. Giving yourself the 5-15 minutes that IM has can give you time to adjust mentally to what is happening as well as reducing possible nausea from the serotonin activity that psychedelics can cause. The one time I IV'd 5-MeO-DMT was a vomit fest for the first ten minutes, but 5-MeO-DMT is known for causing that even orally or snorted.
My single experience with DOC was a 24 hour trip mostly just delegated to sex, and that was 2mg bucally. If you do this, I would start low somewhere around 250 or 500 mcg and see what happens. I would still expect a 16ish hour trip at least.
