I say go for it, can you think of any other way to SKY-ROCKET your risk for tricuspid valve defects? (Except of course a little heroin).
No doubt, shooting homemade stuff sub-Q/IM is sl risky, but leave IV administration to 1) people that know what their doing & 2) (most import) for meds that are approved per FDA (read= ultra-conservative/ridiculous as far as standards for sterility). If IM + bact, still pretty much contained & good chance body will/can fight off & if not meds usually do the trick (many people debate with themselves about 5dys AFTER they should have come in, & majority still do great). You let that shit grow in your bloodstream.....you'll start feeling kinda bad & decide to wait it out, next thing you know your family/bros are carrying your delerious ass to the ED for a "quick" admit upstairs for a nice little visit.
