Do you know why that is not done/recommended? Too much to inject? Burns?
@Sammybackflip gave a decent explanation for this somewhere else. When taking something orally there are a whole bunch of biological actions that slows down ingestion and its potency, going intra muscle or venous removes that. They actually inject SN as a remedy for cyanide poisoning so its an already clinically approved method of delivering SN. The trick I guess is to work out how to make the solution. I will be doing more research on this personally as I have already bought the syringes and needles. Some of my research leads me to believe (and please, I am no pharmacist, doctor or expert) that if I do the oral process and accompany it with a few injections my chances would be increased. My rudimentary math is to put 3gm into 100ml of water and make a bunch of syringes from that solution. My hope is that it would help me reach the unconscious stage quicker. So drink first (as per the instructions in the megathread with the regime etc) as it seems that there is a time period before ingesting and onset of drowsiness, and during that time, give as many injections as possible. So for me, its a belt and braces approach. I live alone and could be gone for months. Only the landlord coming for their rent would be the only person knocking on the door so I don't want to mess it up.
One thing that rarely gets mentioned is that everyone has a different tolerance to SN. 1gm killed one person and another survived 9gm (but that story did not include if medical intervention was used so that story may not be relevant)
