I had lax inj protocol, sometimes still do if im stupid, now i believe alchol is enough, but also i pinned water based, winny, so no benzyl in it into my biceps 3 days before a show-immune system beat down- it swelled up huge warm and red, bc of my “occupation” i was remiss to go to hospital until i knew i had to, which i didn't, i used a bunch of 3 ml 22 gauge 1 1/2s to drain 23 ml of pink out, no stink, no pain, the first 4 syringes filled themselves bc of the pressure, the remaining id put in and pull the plunger with my teeth. Maybe my body woulda beaten it, maybe not. i drenched my hole riddled arm with RA and then took a ton of bactrim for a week. if you look really close my left bi is a lil smaller than my right BUT so is my left tri and forearm bc im right handed so who knows. Point is treat fast, better to drain a good shot and be wrong than wait and be in hospital. we dont cook our UGLs they are solid, and yes when you pin a site repeatedly the scar tissue reduces blood flow and increases the chance of infection, rotate sites, i personally havent used my glutes in a decade. Again i reiterate that ive seen tons of guys get dirt and trash super glued into open wounds while serving in the military and never got sick, the human body is pretty badass, if its firing on all cylinders, unsterilized skin will not guarantee infection, in fact i know pros who dont ever use RA or wipes so theres that and again with thousands of years of gear use on here and we have what like 7-10 incidents, the math on it is pretty solid imo.
