god i dont know what im doing wrong recently this is the second time i think im infected. well can i get someones opinion. i shot up three days ago and my butt is really sore so bad i cant even hardely sit and where i injected is purple is it infected or is it from the ba cause i made a new mix that was 500mg with 5% ba,12%bb and the rest eo any feedback would be great and i always use a fresh needle and syringe and wipe the bottle and injection area.
