a few years ago I got infection after infection and ive been doin gear for about long time ,i drained them while on cipro ,cefalaxon( sp)winny delts ,tne....test cyp in my quads they were hard to drain(had to prop my leg up ! I usually got 12 to 15 cc's of purplish black gooey shit, some had cotton/particles like white shit in it ! I had to use a 18 ga needle1.5 long and a 5cc syringe !and if I didn't hit the spot i'd poke it 2-4 x's till I hit the right spot then once it started flowing/ draining i'd unscrew the needle from the syringe and let it drain for a while into a small plastic Tupperware bowl. I don't really know what happened since I refiltered,baked refiltered over and over again and still got infections. then I quit injecting anything for 5 years now I,m fine but I do have kidney disease and I think that's why I was getting them so often , my immune system was trashed ! a note: once you hit the right spot and drain 2-3 cc's of puss ,drain again once every 3 days till you get nothing in the syrine usually after a week/10 days and stay on cyp/cef till its def. gone.
