Im 16 and ive been takeing steroids for past month,im takeing deca and srt-350.every time i inject the deca its fine but with the srt-350 it swells up and goes red.first time i did it in arse cheek.few days after it was hurting and swelled up but for some reason i got a bump at bottom of my spine abit like a golf ball.but it was fine in a week,then i did my shoulder and its been a week and its still swollen up alot bigger then my other and i have a lump at bottom of my elbow.is this maybe there is somthing up with srt-350 and its infected. or is it normal cos its first time ive tryed it and ive had to much ?
